MAME 0.222

MAME 0.222, the product of our May/June development cycle, is ready today, and it’s a very exciting release. There are lots of bug fixes, including some long-standing issues with classics like Bosconian and Gaplus, and missing pan/zoom effects in games on Seta hardware. Two more Nintendo LCD games are supported: the Panorama Screen version of Popeye, and the two-player Donkey Kong 3 Micro Vs. System. New versions of supported games include a review copy of DonPachi that allows the game to be paused for photography, and a version of the adult Qix game Gals Panic for the Taiwanese market.
Other advancements on the arcade side include audio circuitry emulation for 280-ZZZAP, and protection microcontroller emulation for Kick and Run and Captain Silver.
The GRiD Compass series were possibly the first rugged computers in the clamshell form factor, possibly best known for their use on NASA space shuttle missions in the 1980s. The initial model, the Compass 1101, is now usable in MAME. There are lots of improvements to the Tandy Color Computer drivers in this release, with better cartridge support being a theme. Acorn BBC series drivers now support Solidisk file system ROMs. Writing to IMD floppy images (popular for CP/M computers) is now supported, and a critical bug affecting writes to HFE disk images has been fixed. Software list additions include a collection of CDs for the SGI MIPS workstations.
There are several updates to Apple II emulation this month, including support for several accelerators, a new IWM floppy controller core, and support for using two memory cards simultaneously on the CFFA2. As usual, we’ve added the latest original software dumps and clean cracks to the software lists, including lots of educational titles.
Finally, the memory system has been optimised, yielding performance improvements in all emulated systems, you no longer need to avoid non-ASCII characters in paths when using the chdman tool, and jedutil supports more devices.
There were too many HyperScan RFID cards added to the software list to itemise them all here. You can read about all the updates in the whatsnew.txt file, or get the source and 64-bit Windows binary packages from the download page.

Sympathy for the Drow - De-Vilifying the Dark Elves

The "Evil" races in DnD have always rubbed me kinda the wrong way. Partly once I learned that a lot of them come from racist stereotypes (Orcs, Drow, and Goblins in particular) and also just because it doesn't make sense to me. Even Nazi Germany had variation and dissenters and it only lasted for 12 years. Why would a clearly evil society never change over hundreds of years? In my opinion, a story is only as good as it's villains. So, I've set out to try and make the traditionally evil races slightly more believable and even sympathetic in places.
Now, I've not been a DM very long, only like three years. But the first campaign I ever ran was through Curse of Strahd which paints the Vistani (an itinerant society heavily based on the real world Romani) as a conniving group of thieves, murders, and vampire-worshipers. Thankfully, I found through reddit and other sites how to steer away from the racists depictions of the Vistani and making them seem like, at worst, opportunists. So, I hope to be able to do that with some other of the classic DnD antagonist races.
I've read some other phenomenal post on here about evil races that totally inspired me as well. There's a great two part post about Decolonizing D&D which I adore. The post about alignment is easily my favorite. There's a couple great ones on Orcs and Yuan-Ti too so if some of my ideas are lifted from them, I hope y'all consider it flattery instead of theft. So, here are some primer notes before I get into it.
For creating the Dark Elves, I tried to keep as much as I could from the books. Obviously some stuff has to get thrown out the window though. I also tried to standardize calling them Dark Elves instead of Drow partly because I feel like Drow has a much nastier sound to it and calling them Dark Elves follows the naming convention with the High and Wood Elves. I tried to model them after real-life matriarchal societies like the Mosuo people of China and their pantheon after real deities like the Greeks, Romans, and Norse. I also quickly realized that building a society is inseparable from geography. Where a people are from effects their language, values, mythology, history, and family structure. I've tried to outline details I think are necessary to making this society realistic while leaving it open ended enough to be place-able in different worlds with relative ease. All that aside, lets get into the meat of it.

The Dark Elves: Elven Outcasts

The Elves are a varied and magical people that come from many planes and many environments within them. But none are met with more distrust and fear than the Dark Elves. Easily set apart from their cousins by their charcoal or pitch-black skin, pink-red eyes, hair of grays and whites, and shorter stature, these people have earned a reputation as killers, thieves, demon worshipers, and liars. But history is a cruel mistress, something the Dark Elves know better than most.

The Divine Divide

As the legends go, when the world was still young, Corellon Larethian lived on the Plane of Arvandor with his fellow Primal Elves. They were wild and mutable, emotional and free in all things. They changed shapes at will, gave and took freely to and from the world, and never stayed in any location too long. They wandered to and fro, scattering their peoples across almost every plane. However, this unbridled freedom was not without a price. Arguments, feuds, and small scale wars were incredibly common between them. Some elves would find themselves stranded on far off planes after most of their companions impulsively decided to leave. Their self serving impulses drove them to often completely disregard the needs or wants of others if they went against their own desires. And their reckless revelry was wreaking havoc on the natural world with Elven parties decimating whole planes of edible plants, wild game, and drinkable water.
One such Primal Elf began to see the destruction of their ways and talked to other elves about their actions. Slowly, this Elf by the name of Lolth amassed a small following of devotees that saw the negative ramifications of their inconsiderate freedom. Lolth and her followers agreed to take on fixed forms to show recognition of the dangers that impulsivity could bring. Lolth led this small group of devotees to Corellon to ask for his support. Now, Corellon did not lead these Primal Elves: he was just as wild as the best of them and did not take kindly to others telling him what to do. But he was the First Elf ever born and was universally respected amongst the Primal Elves and if Lolth could convince him, others would surely follow. Corellon listened to her proposition and agreed that they should change to prevent more destruction and conflict, but refused to order his kinsfolk into any action. He was an Elf, same as all of them, and he wouldn’t dare order around his family. He balked when Lolth asked him to take a concrete form as a show of solidarity and brushed her off as a killjoy.
Lolth was unsatisfied with this outcome and her following set out to convince each Elf to change their ways to preserve the beauty of the worlds. However, without the support of Corellon, many elves refused her offer. Her anger grew with each failure and her opinion of Corellon turned sour, something she made no attempt to hide from her Elven siblings. Now, Corellon is a proud god and once he caught wind that Lolth was bad mouthing him in an attempt to win over others, he became enraged. He railed against Lolth calling her a snake-tongued thief and Lolth called him incompetent and cruel. Their tempers flared and all the elves chose sides between Corellon’s freedom and Lolth’s stability. During this great debate, the Primal Elves turned to violence. The Dark Elves maintain that Corellon’s side threw the first blow, while the High Elves claim that it came from Lolth’s side.
No matter the source, this violent outburst soured relations between Lolth and Corellon forever after. He cast her and her followers out of Arvandor and barred her from ever returning. He also cast all but his most trusted kin from Arvandor, forcing them all to live lives on other worlds out of fear of another perceived insurrection. Thus, the Seldarine remain in Arvandor to judge the souls of Corellon’s faithful when they die and Lolth takes refuge in Arcadia with her pantheon where she minds the souls of the Drow. Corellon’s faithful call her pantheon the Dark Seldarine, while her faithful call it the Myrkalfar.

Myrkalfar: The Spider Mother’s House

Lolth the Spider Queen is the unquestioned head of the Myrkalfar, with all other deities seen as her divine family. Lolth is considered at times to be fickle or even cruel, but her ire is never gained without good reason. A very involved deity, her followers constantly search for signs of her favor or scorn in everyday life. When a Dark Elf contemplates a risky or controversial decision, they consult priestesses or perform their own rites which often gives them direct and succinct answers. She serves as an example to matriarchs of Drow families as demanding yet understanding, punishing yet guiding. She asks for a lot of her priestesses, demanding they be an unflinching example of everything a strong leader should be. The Myrkalfar is often presented as a divine household, with Lolth as the matron.
Keptolo is the consort of Lolth and considered to be the ideal of what a male should be. Beautiful and kind, strong and hard working, he helps Lolth in everything she does. Sometimes he serves as a messenger, other times as an agent of redemption, sometimes as a divine healer. When a Dark Elf is tasked with a divine charge, he is usually the one to deliver the message and guide them through their charge. He serves also as a fertility deity and is often worshiped by women or men seeking a child. Outsiders see him as a weak and subservient husband to Lolth, but his faithfulness to his matron is considered a virtue and his status as a “husband” is relatively alien to the Dark Elves as they have no binding marriage in their society.
If Keptolo is the agent of Lolth’s mercy, Kiaransalee is the agent of her vengeance. She is the eldest daughter of Lolth and Keptolo and one that Dark Elves pray to when they feel wronged. Only the most binding and serious contracts are signed under her name. To break an oath made under her name is sure to bring destruction. She is also the governor of the dead, judging the souls of those passed in the afterlife. She opposes the mindless undead created by mortals, but spirits and revenants that return to finish unresolved business amongst the living are considered under her protection. Should a Dark Elf encounter a returned spirit that is seeking vengeance, it’s their duty to leave them on their way and pray that the spirit isn’t there for them. This reverence of certain undead is something many outsiders consider downright evil.
Selvetarm is the Dark Elven warrior goddess and youngest daughter of Lolth. Often depicted with eight arms, she represents the pinnacle of hand to hand martial prowess, but often is without restraint. She serves as both an inspiration for warriors, and a warning. Vhaeraun is the eldest son of Lolth and governs ambition and stealth. Both of these traits are not necessarily vilified, but worship of him is highly scrutinized. Haughty and rash, tales of him often include deceiving his fellow gods for good and ill and more often than not are cautionary ones. He’s depicted as wearing a mask, either as some punishment for endangering Lolth and her family or to hide his identity for various schemes, possibly both.
Malyk is Lolth’s youngest son and a youthful deity of change and growth. He’s often seen as a bouncing young boy that Lolth and her family have to reign in from wild misadventures. His freedom and curiosity is often seen as a double edged sword, both gaining him great riches but also putting him in tremendous peril. He has strong ties to sorcerers and when a child is born with innate magical talent, he is often the one thanked for it. He serves as an outlet for a Dark Elves youthful chaotic nature, but also warns them of the ramifications of their actions.
Ghaunadur is a strange figure in the pantheon. Their place in the family is a bit of a mystery, sometimes called the sibling of Lolth, or her child, or even as Lolth’s parent. What makes them truly unique is that they are a formless deity, something that Lolth once warred with Corellon over. The legends go that when Ghaunadur joined Lolth, they refused to give up their changeable nature. When questioned, Ghaunadur pointed to the slimes, oozes, and formless creatures of the world and said that they wished to protect them from the Elves and the Elves from them. Lolth agreed, cementing their position as the deity of the changing forms of nature. Their favored creature is the ooze, but they govern all natural creatures. Dark Elves often pray to Ghaunadur to protect them from the creatures that lurk in the depths of the forest.
Zinzerena is Lolth’s sister and is the goddess of poisons, illusions, and magic. Viewed as an elderly and patient figure, she often serves as council to Lolth in desperate times. She’s said to be the mother of all poisons and venoms and her teachings are all about finding the wisest solution to a problem. Zinzerena teaches that even though the spider is small, it’s bite can still fell a panther. Despite her perceived age, she’s considered the younger sister of Lolth and is thought to be incredibly quick and nimble: a reminder that not everything is as it seems.
Eilistraee is Lolth’s niece and daughter of Zinzerena. Considered the black sheep of the pantheon, she serves as a goddess of redemption and moonlight. Dark Elves that turn their back on their family or scorn traditions will sometimes find themselves turned to Driders, half-spider half-Dark Elf creatures shunned by all. Eilistraee is said to watch over these creatures and if they are repentant, offer them challenges that they could complete to redeem themselves. Lolth often views her with contempt or mistrust, but never hates her and maintains her place in the pantheon. Dark Elven faithful rarely worship her as the others. She’s also one of the only deities of the Myrkalfar to claim no animosity toward the Seldarine and their faithful.
Spiders are the sacred animal of Lolth and are often used as an example of social order and the importance of family bonds. Each strand of silk serves the web as whole. More literally, the giant spiders of the Underdark are multifaceted and incredibly useful creatures. Serving as beasts of burden, war steeds, meat producers, household guardians, and silk producers, they are present in almost every facet of society. Their silks are used in everything from wound dressings to armor to architecture. To kill or steal another family's spider is considered akin to stealing a member of the family. Smaller and more poisonous spiders are often kept in temples and their webs are used as divining tools for priestesses.

Elven Exiles

The recorded history of the Dark Elves is full of contradictions from High Elf and Dark Elf sources. What historians can agree on is when the Elves of the Prime Material arrived, the followers of Lolth secluded from their Wood and High cousins and retreated into the Azelarien, also known as the Green Sea in Common. A massive forest, nearly 1 million square miles of dense and vibrant trees, that grows denser and darker the farther in one ventures. For countless eons, the High, Wood, and Dark Elves lived in relative harmony in their own corner of the world. High Elves lived near the forests in towns and villages, the Wood Elves lived in the lightly forested outlands of the Green Sea, and the Dark Elves lived deep in the central forests which was so dense that very little light reached the forest floor.
As time passed and their villages turned to cities, the High Elves began expanding into the forest, chopping some down to build homes and heat their furnaces. This began pushing into the territory of the Wood Elves and eventually the Dark Elves as well. These two peoples formed a shaky alliance to push back the expansive tide of the far larger High Elven armies. This alliance proved successful however and the High Elven forces began losing ground. What happened next is a matter of some debate. High Elven historians attest that the Dark Elven armies used Wood Elven soldiers as unwitting bait to lure the High Elven armies into a trap, thus causing a schism between them. Dark Elven historians state that the Wood Elven armies turned on them after the Wood Elves met in secret with High Elven leaders and bargained for their independence. Some Wood Elven historians claim that after a brutal defeat on the field, they were met by High Elven dignitaries that offered them clemency if they turned on their allies. They initially refused, but after the dignitaries threatened to make the same offer to the Dark Elves, they had no choice but to accept. No matter the cause, the histories agree that the Wood Elves turned on their erstwhile allies and helped push the Dark Elves into a rapid loss of ground.
Facing the might of the two armies with their own relatively small one, the Dark Elves were beaten into a hasty retreat into their own territory. Losing every open encounter, the Dark Elf matrons developed a new strategy of combat. The armies switched from training as many as quickly as they could, to training only a select few in multiple different forms of combat and magic. As the High and Wood Elves advanced into their territory, they quickly found their supply lines cut out from under them, their soldiers ambushed while sleeping, their scouts captured, and their leaders assassinated. And even if they would make it to a Dark Elf settlement, they would find it abandoned and booby-trapped, warned by their fast and silent scouts. If the Dark Elves couldn’t face their enemies head-on, they would weaken them with quick and decisive strikes.
Eventually, the war ground to a stalemate. The High Elves couldn’t push into the Dark Elf territory far enough to capture any cities of note without taking severe casualties and the Dark Elves were only managing to hold the invading armies back and couldn’t muster a force strong enough to push back to the enemy capital. Thus, the war cooled into a tense peace. The leaders came together to draw borders, but neither side fully forgave nor forgot one another’s actions. High and Wood Elves viewed the change in tactics by the Dark Elves as an unethical violation of the standards of war. The Dark Elves felt a particular animosity toward the Wood Elves, considering them backstabbers in their darkest hour.

Dark Elf Families: Matrons of Order

The Dark Elf society, to an outsider, looks like an oppressive and cruel society of slave traders and backstabbers. But the truth is more subtle. The Dark Elves value tradition and filial piety above almost all else. To a Dark Elven citizen, their family name is their most valuable possession and they are taught from a very young age that to look after their parents and their younger siblings is the highest virtue. Ancestors that have achieved great things often have shrines in a household alongside the gods themselves. A Dark Elf going against the will of their family is considered one of the highest taboos and often causes them to be outcast from Dark Elven society as a whole. Dark Elf society is matrilineal meaning that the eldest woman in each family is revered as the household leader and receives great respect from her family and society. This also means that the males of the society don’t inherit wealth as frequently as the females.
Dark Elven families are quite large, often with multiple generations along with aunts, uncles, and cousins living in the same household. New children almost always reside with their mother. Males of the society are expected to care not for their own biological children, but for the children born to their sisters, aunts, or nieces. This results in a striking amount of sexual freedom for both men and women, but is often viewed from the outside as promiscuity. The Dark Elves do not marry in the traditional sense, instead favoring long term partners with one another that can end at any time with no concerns to material wealth or ownership.
However, to become a member of a Dark Elf family is not entirely a matter of heritage. When a family that cannot support another child has one, they are often adopted by more well to do families and raised as one of their own. These adopted children are considered just as legitimate as if they were born into the family. Also, should a family lose all their heirs or become destitute, they often ask to become assimilated into other families for their own safety. The latter is considered a morose ceremony as the members of the smaller family forsake their surnames. To take in such a family is both an extreme honor and grim burden, as it means ending another family's line.
The borders of Dark Elven civilization only goes so far as there are trees so many newer up and coming families have expanded underground, a difficult and slow endeavor. This has put multiple houses at odds with one another for territory. However, Dark Elves do not tolerate open hostility between families as they have a very strong sense of collective identity. Dark Elves do not war against fellow Dark Elves, same as a spider does not fight its own web. This leads to many tensions and conflicts needing to be resolved in other ways. Most families will attempt a diplomatic solution, but when that isn’t an option, sabotage and coercion is the favored outlet. Murder is considered a bridge too far by most houses, but subterfuge in almost every other facet is, while not accepted, tolerated.
Legends of Lolth’s rebellion and the tension of their enclosed territory have imbued the Dark Elves with a strong sense of symbiosis with nature and conservancy. Sustainable living is the cornerstone of Dark Elf society. In the wild, no creature is killed or plant destroyed unless it’s a matter of self defense or necessary to survival.

Dark Elven Sex and Gender

As with many Elven peoples, sexuality is seen as a fluid and non-binary matter. Same sex relationships are usually seen as just as acceptable as male-female relationships. Since Dark Elves have no marriage structure, same sex life partners are common and widely accepted. Inheritance is passed along by the family as a whole, not linearly, meaning some houses may have matrons with no direct biological descendants while still serving at the elder matron. Power dynamics in relationships are still a factor, with the elder female in a gay relationship considered slightly above their partner socially and is seen as the inheritor in cases of property or genealogy. Male same sex relationships are accepted with little controversy. Since children are passed down their mothers line, the males have no social obligation to sire an heir as with other societies.
Transgender and transexual Dark Elves are met with slightly more controversy. Lolth’s rejection of the Primal Elves mutable forms is sometimes cited against transgender and transexual Dark Elves. Ghaunadur, however, is considered the patron god of these people and teaches that just as they are part of nature, they can change their forms. Many of these people join the religious order of Ghaunadur, serving in various roles both in religious ceremonies and as forest guides. Some even consider them to be blessed by Ghaunadur and are highly sought after in forays into the forests for protection. Children born to transgender Dark Elves are still expected to be a part of their eldest mother’s family or eldest father if no woman is part of the union.

Slavery Amongst the Dark Elves

While the Dark Elves do take slaves, their slavery doesn’t look the same as many other societies. When a family becomes indebted to another and they cannot pay off the debt, a member of their family, usually male, will be sent to work for the owed family. They give him room and board and are expected to care for him as if he were one of their own. He’ll work for them for an agreed upon amount of time before returning to his native family. Injury or misuse of this person is often grounds for them to leave and the debt to be nullified. Children born to servant fathers needn’t worry about inheriting their father’s status since they’re considered to be their mother’s child. On the rare occasion that a female servant has a child while in servitude, the child is returned to the mother’s family to be raised by her family while she works off the remaining debt. Some trade of servants does occur between houses, with indentured servants being traded for goods or services or even other servants of special skills, but the family of the servant reserves the right to veto such a trade for any reason.
During their frequent clashes with external armies, the Dark Elves do sometimes take prisoners of war, though very rarely are they used for slave labor. They never bring them back to major settlements, often keeping them on the outskirts of their territory to prevent them from learning critical knowledge of their territory. Most prisoners are held as bargaining chips to be traded for passage, supplies, or captured Dark Elves. Captured military leaders are sometimes brought to Dark Elven cities to be tried for their crimes against their people.

Dark Elven Government: Independent Houses

Unlike many other cultures, the Dark Elves lack a centralized government. Societal etiquette govern the standard for how certain crimes and disagreements should be handled, but each family unit acts as its own governing body. Disagreements within families are thus resolved internally. Inter-family disputes are resolved in multiple different ways. Most often, the two matrons of the family will meet and agree on terms to fairly compensate both sides. In cases when these talks deteriorate, the High Priestess of Lolth is often called to serve as the mediator and serves as the ruling body between disputes. Her rulings are final and indisputable, as she is considered the mouthpiece of Lolth’s will.
In times of crisis, historically the many houses of the Dark Elves have convened to discuss threats to all of Dark Elven society. This is uncommon as it’s difficult logistically to gather all the matrons in the same place at the same time, so often houses are represented by either the second eldest woman of the family or the eldest daughter of the matron. The High Priestess of Lolth often resides over these meetings as an arbiter in the event of split decisions or in delivering guidance from Lolth herself.

There's my take on the Dark Elves. Any comments, suggestions, questions, outrages, and critiques are welcomed. This is my first comprehensive look at a whole race so if I've missed things, I'll try and patch them up. I'd like to do similar things for Orcs, Goblinoids, Kobolds, and others so those might be seen soon. Thanks!

LCD Arduino project Display Heart Rate

LCD Arduino project brief introduction
Some time ago, I found a heart rate sensor module MAX30100 in shopping online. This module can collect blood oxygen and heart rate data of users, which is also simple and convenient to use.
According to the data, I found that there are libraries of MAX30100 in the Arduino library files. That is to say, if I use the communication between LCD Arduino and MAX30100, I can directly call the Arduino library files without having to rewrite the driver files. This is a good thing, so I bought the module of MAX30100.
I decided to use Arduino to verify the heart rate and blood oxygen collection function of MAX30100. With STONE TFT LCD screen for monitoring blood pressure.
Note: this module by default only with 3.3 V level MCU communications, because it defaults to using IIC pin pull up the resistance of 4.7 K to 1.8 V, so there is no communication with the Arduino by default, if you want to commune with the Arduino and need two 4.7 K of the IIC pin pull-up resistor connected to the VIN pin, these contents will be introduced in the back of the chapter.

Functional assignments

Before starting this project, I thought about some simple features:
• Heart rate data and blood oxygen data were collected
• Heart rate and blood oxygen data are displayed through an LCD screen
These are the only two features, but if we want to implement it, we need to do more thinking:
• What master MCU is used?
• What kind of LCD display?
As we mentioned earlier, we use Arduino for the MCU, but this is an LCD Arduino project, so we need to choose the appropriate LCD display module. I plan to use the LCD display screen with a serial port. I have a STONE STVI070WT-01 displayer here, but if Arduino needs to communicate with it, MAX3232 is needed to do the level conversion.
Then the basic electronic materials are determined as follows:
  1. Arduino Mini Pro development board
  2. MAX30100 heart rate and blood oxygen sensor module
  3. STONE STVI070WT-01 LCD serial port display module
  4. MAX3232 module

Hardware Introduction

MAX30100

The MAX30100 is an integrated pulse oximetry and heart rate monitor sensor solution. It combines two LEDs, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse oximetry and heart-rate signals. The MAX30100 operates from 1.8V and 3.3V power supplies and can be powered down through software with negligible standby current, permitting the power supply to remain connected at all times.

Just press your finger against the sensor to estimate pulse oxygen saturation (SpO2) and pulse (equivalent to heartbeat).
The pulse oximeter (oximeter) is a mini-spectrometer that USES the principles of different red cell absorption spectra to analyze the oxygen saturation of the blood. This real-time and rapid measurement method is also widely used in many clinical references.
I will not introduce the MAX30100 too much, because these materials are available on the Internet. Interested friends can look up the information of this heart rate test module on the Internet, and have a deeper understanding of its detection principle.

Introduction to the STVI070WT-01 displayer

In this project, I will use the STONE STVI070WT-01 to display the heart rate and blood oxygen data.
The driver chip has been integrated inside the display screen, and there is software for users to use. Users only need to add buttons, text boxes, and other logic through the designed UI pictures, and then generate configuration files and download them into the display screen to run.
The display of STVI070WT-01 communicates with MCU through the UART RS232 signal, which means that we need to add a MAX3232 chip to convert the RS232 signal into a TTL signal so that we can communicate with Arduino MCU.

Development steps

Three steps of STONE display screen development:
• Design the display logic and button logic with STONE TOOL software, and download the design file to the display module.
• MCU communicates with the STONE LCD display module through the serial port.
• With the data obtained in step 2, the MCU does other actions.

STONE TOOL software installation

Download the latest version of the STONE TOOL software (currently TOOL2019) from the website, and install it.
After the software is installed, the following interface will be opened:

https://preview.redd.it/evuct2w630a51.jpg?width=848&format=pjpg&auto=webp&s=201d40fdb81e2c4fd229992daf15501f2cb177a0
Click the "File" button in the upper left corner to create a new project, which we will discuss later.

LCD Arduino

Arduino is an open-source electronic prototype platform that is easy to use and easy to use. It includes the hardware part (various development boards that conform to the Arduino specification) and the software part (Arduino IDE and related development kits).
The hardware part (or development board) consists of a microcontroller (MCU), Flash memory (Flash), and a set of universal input/output interfaces (GPIO), which you can think of as a microcomputer motherboard.
The software part is mainly composed of Arduino IDE on PC, related board-level support package (BSP) and rich third-party function library. With the Arduino IDE, you can easily download the BSP associated with your development board and the libraries you need to write your programs.
Arduino is an open-source platform. So far, there have been many models and many derived controllers, including Arduino Uno, Arduino Nano, Arduino Yun and so on. In addition, the Arduino IDE now not only supports the Arduino series development boards but also adds support for popular development boards such as Intel Galileo and NodeMCU by introducing BSP.
Arduino senses the environment through a variety of sensors, controlling lights, motors and other devices to feedback and influence the environment. The microcontroller on the board can be programmed with an Arduino programming language, compiled into binaries, and burned into the microcontroller. Programming for Arduino is implemented with the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino-based projects can contain Arduino only, as well as Arduino and other software running on PC, and they communicate with each other (such as Flash, Processing, MaxMSP).

HMI for Arduino serial display TFT LCD project development environment

The Arduino development environment is the Arduino IDE, which can be downloaded from the Internet.
Log into the official website of Arduino and download the software
https://www.arduino.cc/en/Main/Software?setlang=cn
After installing the Arduino IDE, the following interface will appear when you open the software:

https://preview.redd.it/2ajmkke830a51.jpg?width=567&format=pjpg&auto=webp&s=56dc9dd01c98b231c782ef94d24a9f620c4897b3
The Arduino IDE creates two functions by default: the setup function and the loop function.
There are many Arduino introductions on the Internet. If you don't understand something, you can go to the Internet to find it.

LCD Arduino Project implementation process

hardware connection

To ensure that the next step in writing code goes smoothly, we must first determine the reliability of the hardware connection.
Only four pieces of hardware were used in this project:
  1. Arduino Mini pro-development board
  2. STONE STVI070WT-01 TFT-LCD display screen
  3. MAX30100 heart rate and blood oxygen sensor
  4. MAX3232 (rs232-> TTL)
The Arduino Mini Pro development board and STVI070WT-01 TFT-LCD display screen are connected through UART, which requires level conversion through MAX3232, and then the Arduino Mini Pro development board and MAX30100 module are connected through IIC interface. After thinking clearly, we can draw the following wiring picture:

https://preview.redd.it/w2e5c9ha30a51.jpg?width=769&format=pjpg&auto=webp&s=95129db838d6c358e986c88a4d1348f4783cd0ab

Make sure there are no errors in the hardware connection and proceed to the next step.

STONE TFT LCD user interface design

First of all, we need to design a UI display image, which can be designed by PhotoShop or other image design tools. After designing the UI display image, save the image in JPG format.
Open the software STONE TOOL 2019 and create a new project:

https://preview.redd.it/sqjii2mc30a51.jpg?width=1004&format=pjpg&auto=webp&s=12f0a87d6c2ca8decaff241d5a0b50a3a1aece89
https://preview.redd.it/4ta8cdlc30a51.jpg?width=871&format=pjpg&auto=webp&s=b31ac5e612a2c809e29f63974a04ba25bff83788
Remove the image that was loaded by default in the new project, and add the UI image that we designed.
Add the text display component, design the display digit and decimal point, get the storage location of the text display component in the displayer.
The effect is as follows:

https://preview.redd.it/2mfqapoe30a51.jpg?width=1335&format=pjpg&auto=webp&s=aacfa0fde88defacd127ea9d9d27ab006ab618dd
Text display component address:
• Connection sta : 0x0008
• Heart rate : 0x0001
• Blood oxygen : 0x0005
The main contents of the UI interface are as follows:
• Connection status
• Heart rate display
• Blood oxygen showed

Generate configuration file

Once the UI design is complete, the configuration file can be generated and downloaded to the STVI070WT-01 displaye.

First, perform step 1, then insert the USB flash drive into the computer, and the disk symbol will be displayed. Then click "Download to u-disk" to Download the configuration file to the USB flash drive, and then insert the USB flash drive into STVI070WT-01 to complete the upgrade.

MAX30100

MAX30100 communicates via IIC. Its working principle is that the ADC value of heart rate can be obtained through infrared led irradiation. The MAX30100 register can be divided into five categories: state register, FIFO, control register, temperature register, and ID register. The temperature register reads the temperature value of the chip to correct the deviation caused by the temperature. The ID register can read the chip's ID number.

https://preview.redd.it/221fq8vg30a51.jpg?width=848&format=pjpg&auto=webp&s=43e93284ac35cf1944a77d79ff9a2f662e540c7e

MAX30100 is connected with the Arduino Mini Pro development board through the IIC communication interface. Because there are ready-made MAX30100 library files in the Arduino IDE, we can read the heart rate and blood oxygen data without studying the registers of MAX30100.
For those who are interested in exploring the MAX30100 register, see the MAX30100 Datasheet.

Modify the MAX30100 IIC pull-up resistor

It should be noted that the 4.7k pull-up resistance of the IIC pin of MAX30100 module is connected to 1.8v, which is not a problem in theory. However, the communication logic level of the Arduino IIC pin is 5V, so it cannot communicate with Arduino without changing the hardware of the MAX30100 module.Direct communication is possible if the MCU is STM32 or another 3.3v logic level MCU.
Therefore, the following changes need to be made:

https://preview.redd.it/jti57usl30a51.jpg?width=521&format=pjpg&auto=webp&s=c56b1b1a8294d60a8f9e931e411305f68c5c5559
Remove the three 4.7k resistors marked in the picture with an electric soldering iron. Then weld two resistors of 4.7k at the pins of SDA and SCL to VIN, so that we can communicate with Arduino.

Arduino serial display LCD

Open the Arduino IDE and find the following buttons:

https://preview.redd.it/990d3bdp30a51.jpg?width=853&format=pjpg&auto=webp&s=24136c385601b69d5afc67842358b102373277ef
Search for "MAX30100" to find two libraries for MAX30100, then click download and install.

After the installation, you can find the Demo of MAX30100 in the LIB library folder of LCD Arduino:

https://preview.redd.it/rn05xgvw30a51.jpg?width=911&format=pjpg&auto=webp&s=3709bc7c5be36ebdd14c01cb0b7c1933953425b0

This Demo can be directly tested. If the hardware connection is ok, you can download the code compilation into the Arduino development board and see the data of MAX30100 in the serial debugging tool.

This code is very simple, I believe you can understand it at a glance. I have to say that the modular programming of Arduino is very convenient, and I don't even need to understand how the driver code of Uart and IIC is implemented.
Of course, the above code is an official Demo, and I still need to make some changes to display the data to STONE's displayer.

Display data to the STONE display through Arduino LCD

First, we need to get the address of the component that displays the heart rate and blood oxygen data in STONE's displayer:
In my project, the address is as follows:
Heart rate display component address: 0x0001
Address of blood oxygen display module: 0x0005
Sensor connection status address: 0x0008
If you need to change the display content in the corresponding space, you can change the display content by sending data to the corresponding address of the display screen through the serial port of Arduino.
The modified code is as follows:
