BU9796 prototype finally comes to light ✨🔧🖥️

We covered the BU9796 a loooooooooong time ago on the Great Search while looking for an I2C LCD segment driver ...

but sadly, we never got around to making that breakout board. Til' now! This one features the FS series of the chip, which has some more segments: in this board, we expose 4 common and 18 segments to keep the board from getting too big. This chip runs at 3V or 5V, so it should be easy to use with any device. We still need to figure out what VLCD connects to - some parts of the datasheet say VDD, and some say VSS, so we left a jumper on the back. That way, we can connect it correctly when we are more awake. Stemma QT makes this a plug-and-play driver for just about any micro! Coming soon…

WARNING: LONG ASK INCOMING

For hobby electronics there’s two major kinds of processors: Microcomputers and Microcontrollers. Microcomputers are small full computer systems like the Raspberry Pi, they typically run a general-purpose OS (typically some flavor of Linux) and are useful for the kinds of projects that require basically a full computer to function, but not necessarily individual sensors. They’re a great place to start for people who don’t know a whole ton about programming or working with individual components because they typically can output a true GUI to a screen and have the capabilities of a regular desktop computer. They have a main processor, true RAM, and either large on-board storage space or a way to read a storage device, like an SD card.

Microcontrollers are less complicated (component wise) than microcomputers, but as a result are more difficult for total beginners to begin working with. They’re typically primarily a SoC (System on a Chip) processor without discrete RAM modules and a very small EEPROM (on-ship storage space) and need to have components wired and configured to them to be able to do much more than being a fancy calculator. They’re used for when you need something to carry out electronic functions or get sensor readings, but not necessarily a full operating system, so they’re best suited for small/integrated applications. Your helmet uses a microcontroller to control the LEDs you used in the Cunt Machine post.

I build high-power model rockets as a hobby and with my university team, so I work with both kinds of processor as part of designing payload systems. I typically prefer microcontrollers in these as most of what we do doesn’t need an actual OS to run, and they’re smaller/lighter than microcomputers. One of the advantages of a microcontroller is that it runs a Real-Time OS (RTOS) which forgoes all the user-friendliness of things like windows and linux to instead be the bare minimum backend necessary to run code uploaded into the processor. 

The main advantage of using a microcontroller is really that they’re typically a lot cheaper than microcomputers are and are plenty powerful for really embedded applications. They also make other parts of whatever system is being built cheaper/easier to integrate because they require less overhead to function - the raspberry pi needs a minimum of 5 volts of power to work, while a chip like an ESP32-PICO can run at 1.8V. 

The main way you make sensors/buttons/peripherals work with a microcontroller is via digital communication busses. There’s a few protocols, the most common being I2C, SPI, and UART. I’ll talk about I2C since that’s generally the most common. With I2C each component is assigned a 2-byte “address” that they’re identified by. When the controller sends a request signal on the I2C data bus, every sensor along the line will return their own signal, marked with their address so that they can be identified. It allows for a large number of devices to be put on the same lines and you can daisy-chain them through each other to the microcontroller.

I’ll be honest I really can’t think of a good way to say much more on the subject as like a starting message because I’ve been working with computers so long all the tech stuff for me is second nature, but if you have any questions ask away I can probably answer them or google them.

Emptying out my childhood Lego Robotics competition set so that I can pack all my adult electronics stuff into it for the move. The more things change the more I am still carrying around hundreds of tiny robot and sensor parts I never use. I wish we had FIRST robotics around here but this was a decent alternative, I got to go abroad the one time we actually committed to being real competitors.

There was a point in the distant past when my buddies and I could spring this definitely-not-all-legal-Lego-building-techniques beauty up from this kit in 15 minutes flat. From memory!

I spent a moment seeing if I could will the muscle memory to build that sensor mount back into existence and I cannot, that's what a decade without practice does to you.

Anyways time to stuff this box full of FPGA's and i2c devices.

[irradiate-space]

Adafruit is dangerous.

No, I didn't know I wanted a click-wheel sensor and the corresponding I2C encoder board. Do I have the perfect project for it? Yes. Is this device going to have so many inputs? Also yes. There's a little I2C analog-stick/4-button gamepad, too.

[intercal]

yesterday I got in the mail:

arduino nano every

rotary encoders (basically a dial that you can keep turning and doesn't have a start/stop)

plastic knobs that DON'T FIT THOSE ROTARY ENCODERS REEEEEE

some new, different EEPROMs that aren't single-wire and are clock-driven instead

I found an addressable RGB (well, BGR) LED strip that I bought like 6 years ago and hey presto it still works!! back in 2018 I had it hooked up to a Teensy, and the Teensy would take commands over serial to display colors on the LED strip, and I would have a Python program watching pulseaudio on my PC and change the colors based on something that @earthnuker wrote (that I'm trying to decipher again) so that bass would show up as red and high notes would show up as blue. ish. I have a video on tumblr of this from that point but siikr is still down so I can't find it. this is all to say that I bought the Nano for this purpose, or at least prototyping putting this into a compact package so it Just Werks (TM). I am remiss about using an entire breakout board to do this though, I've got a handful of STM32F030 chips sitting around and they may be better suited for this idk. it'll probably be good for a prototype so I can reuse the Arduino at a later date since that sucker was $20 and the STM32 chips are like $1 (but are literally just the microchips that you have to solder on to a PCB yourself)

Rotary encoders are for that dumb Arcblip game that I want to turn into a device. I want to use that as the peripheral to control spinning the little circle around, rather than using buttons to do that. I also discovered that it has a push-to-click functionality too, so I don't even need an external button if I go this route. looks cool, datasheet is horrible. the knobs I bought for the encoder have the D-shaped holes, rather than a knurled circle - they didn't fucking have this on the mouser.com page, you literally had to LOOK AT THE DATASHEET FOR A PIECE OF PLASTIC. I am still salty about this. so they're basically useless, I will take them to canada for @party-slug to use instead.

finally the EEPROMs are 24AA02IDs, they are clock-driven instead of single wire. the AT21CS01 device I was trying to get working previously was really cool but it depended on microsecond precision, some operations literally needed to last 1-2µs maximum which the STM32F030 couldn't quite handle. it felt very loose and I couldn't ever get it to work, so I think I needed a faster processor (also, it would start in "high speed mode" instead of the lower "standard" speed, wtf). so now I'm going to try out using this device where I define how fast the clock goes, it can handle ranges from 100khz-400khz which is a lot easier to manage. it's not quite I2C, but it should be more reliable than the stupid time-and-edge based chip I was using before.

thanks for reading my blog

hi. um. i need help. ive been having an issue for months now where sometimes my touchpad will stop working and it'll fix on a restart, but now its stopped working entirely. checking device manager shows that the I2C HID Device has a code 10 error ("This device cannot start. A request for the HID descriptor failed.") .

im not very computer savvy when it comes to drivers but i was able to update the Serial IO and touchpad drivers, and that did absolutely nothing. disabling and re-enabling the device does nothing. reddit suggests using regedit, which im terrified of, or that it could be a hardware issue, which doesn't feel right in this case because restarts previously helped.

there's no pattern to when the touchpad would stop - i was in the middle of typing a tumblr post and trying to get the windows emoji menu to work when it broke. i dont remember how long ive had this laptop and i dont remember the status of the warranty, and i dont want to replace it because its completely fine otherwise and im sick of having to replace laptops.

i dont know what to do. please help.

GY-511 module includes a 3-axis accelerometer and a 3-axis magnetometer. This sensor can measure the linear acceleration at full scales of ± 2 g / ± 4 g / ± 8 g / ± 16 g and magnetic fields at full scales of ± 1.3 / ± 1.9 / ± 2.5 / ± 4.0 / ± 4.7 / ± 5.6 / ± 8.1 Gauss. When you place this module in a magnetic field, according to the Lorentz law, a current is induced in its microscopic coil. The compass module converts this current to the differential voltage for each coordinate direction by calculating these voltages, you can calculate the magnetic field in each direction and obtain the geographic position. It communicates using I2C communication protocol and the voltage level required to power this device is 3V-5V. You can use it in DIY GPS system, accelerometer data acquisition system to be used in Vehicles etc.

Let me introduce my current main WIP. It's not fandom related, it's for my model railroad, and it's not yet finished.

This is a rendering of a circuit board that I'm designing at the moment. It will be a DCC command station. My model railroad is run digitally, which means the tracks carry digital signals that tell each locomotive and switch individually how to run, which lights to turn and so on. The command station is the device that generates that. I have a number of different layouts, one of which has a good command station, one of which has a crappy old one, and the final one isn't even digital yet. So this will be the one that solves all issues for me, hopefully.

The design above isn't finished yet, and even the parts that are are not yet fully representative. The different capacitors are just there as options; some screen print overlaps; and some components (in particular all plugs and the relays that control the programming track) don't have 3D models so they don't show up.

Planned features:

Four layer board

10-25 V DC output, software controllable

Up to 5A output power, limited mainly by the main switching regulator.

Input 15-25V either AC or DC with polarity protection, selectable with some solder bridges (not yet in there). Optionally you can also bypass the main power regulator with another solder bridge (that I haven't added yet); useful in case you use e.g. a laptop power supply with a switchable voltage and don't need any regulation after that.

Railcom support

USB connection; not yet sure what for, but the main chip I'm using has USB support and I have some spare USB connectors here, so in it goes.

Speaking: The chip is an STM32L433RCT6P, chosen because I found it in stock at an electronics distributor. 64 kB RAM, 256 kB EEPROM, with support for an additional up to 256 MB externally (there's a spot for that on the board) and lots of fun extras that I don't technically need. It has an FPU! I don't need an FPU, but I will definitely do some floating point math computation on it just for fun.

Main external connection is WLAN using an ESP32 WROOM U module. I haven't decided on the housing, but I may go for extruded aluminum, so it's the U version that allows and requires an external antenna

It supports XBUS/XpressNet connections for old throttles from Lenz and Roco that I should probably throw away, but I paid good money for them, dang it.

It supports CAN for LCC / OpenLCB. I may not populate this part on all boards that I'm building, because I haven't actually decided whether I am interested. But the chip has CAN functionality built in, so why not.

There's an I2C connection to connect a cheap tiny OLED display for status messages.

Test points for all important signals (in particular the different internal voltage levels; yes, there is 3.3V, A3.3V and -3.3V and I need all of them).

Stuff still to add:

I will add pin headers (or space for pin headers anyway) for all the remaining pins on the STM32, and perhaps some on the ESP32, for future expansions.

Status LED and stop/go button on the front

Wire it all up, maybe move some stuff (mostly the STM32 around), which will cause all sorts of fun new routing issues.

Adjustments to make the jacks line up with the front panel once I've decided on a housing.

Features I'm not considering adding:

s88. I vaguely know what it is but I don't have any devices like that, and if that ever changed I could probably build (or perhaps buy) a converter that connects them via CAN.

Other buses like LocoNet.

Ethernet. I don't need it and it's actually more expensive than WLAN in this day and age.

In terms of software, I'm planning to use DCC-Ex on it. The whole project actually started out as a DCC-Ex shield, but once I realised that this wouldn't fit, I decided to make it standalone. Now, DCC-Ex is designed for Arduino, not STM32, and it doesn't support XpressNet, nor OpenLCB, nor Railcom, and their Wifi protocol is pretty weird and annoying which will be an issue (I'm planning to write my own control app for iPhone for it), so I'll probably change that or just replace it with the z21 one… so really, the software will not look a lot like DCC-Ex once I'm done with it.

Will this all work? I have honestly no idea. I mean, I'm fairly confident, I'd have given up on this long ago otherwise, but I have no guarantees either way until I've spent a lot of money on components and circuit boards and start soldering. Turns out doing it this way is not really cheaper than just buying a half-way decent one. That's what makes it exciting, though!

If it does work, obviously this will be released as open source. But it's still going to be a few days (more realistically weeks) before it's even ready to order the parts, and then a lot of soldering (current BOM stands at 194 actual components), and then a lot of software development before it's ready for that.

Actually there is a difference!

An “app” is specifically a GUI application, usually on a mobile device such as a smartphone. “Program” is a more general word.

“Machine” refers to a full computer, usually a desktop or laptop. “Device” can be more general depending on the context — even just a barometer can be an I2C device, for example.

(This is all off the top of my head so don’t come after me for spreading misinformation)

I hate how everything's called devices and apps now. Those are frail words with no weight and show no respect like machine and program do.

DS2484 I2C to 1-Wire converter

In theory, there's a lot of 1-Wire devices out there, but in reality almost everyone uses 1-Wire for DS18b20 temperature sensors. the long wire lengths and ease of 'chaining' by sharing a single bus wire makes it perfectly fine for this purpose. you can bitbang 1Wire on most microcontrollers, and some SBCs like Raspberry Pi have kernel module support. (https://learn.adafruit.com/adafruits-raspberry-pi-lesson-11-ds18b20-temperature-sensing) But there might be chips without the 1-Wire capability, or maybe you want to use 1-Wire devices on your desktop computer or other SBC with I2C but no 1W.

by special request! this is a DS2484 (https://www.digikey.com/short/5f85v4tf) Stemma QT board that uses the newest I2C-to-1W controller chip, with ESD protection and support for split supplies. you can easily connect it to an existing I2C bus and then use the screw terminals to attach multiple DS18b20's - this library looks promising (https://github.com/pilotak/DS248X) for Arduino. Coming soon!

Yes, I2C has indeed been a target for hackers in Apple devices and other smartphones because it facilitates crucial communication between internal components, making it a potential attack vector.

In certain hardware-based attacks, hackers have exploited I2C connections on Apple devices to gain unauthorized access to components or inject malicious code. By intercepting or manipulating data on the I2C bus, attackers can sometimes interfere with how the device's sensors or processors function.

One notable example of such an attack was the Checkm8 exploit, which exploited a vulnerability at the bootrom level in Apple’s A-series chips. While not specific to I2C, exploits like this sometimes use low-level access points that involve I2C-connected components to interfere with device security. However, direct attacks on the I2C bus are less common due to the complexity and physical access required, but I2C remains a sensitive area in hardware security.

Apple has since implemented enhanced hardware security measures, including Secure Enclave and sandboxing, to protect inter-component communications, making it more difficult to hack I2C on newer devices.

Compilers and Toolchains

GCC (GNU Compiler Collection): Widely used for compiling C and C++ code for embedded systems. It supports various microcontroller architectures and is essential for low-level programming.

ARM Toolchain: A collection of tools used to develop applications for ARM-based microcontrollers. It includes a compiler, assembler, and linker, providing everything needed for embedded development.

Debugging Tools

JTAG/SWD Debuggers: Hardware debuggers like J-Link or ST-Link provide a means to debug embedded systems at the hardware level, allowing for real-time code execution and monitoring.

Serial Monitors: Tools that enable communication between your computer and the microcontroller via serial ports. They are useful for debugging and monitoring output during development.

Techniques for Embedded Programming

Start with a Simple Project Begin with a basic project that interests you, such as blinking an LED or reading a sensor. This hands-on experience will help you understand the fundamentals of embedded programming and familiarize you with the tools.

Learn C/C++ Basics Most embedded systems are programmed in C or C++, so having a strong grasp of these languages is essential. Focus on key concepts such as data types, control structures, and pointers, as these are frequently used in embedded programming.

Understand Hardware Basics Familiarize yourself with the hardware you are working with, including pin configurations, voltage levels, and peripheral interfaces (like I2C, SPI, UART). Knowing how to interact with the hardware is crucial for successful embedded programming.

Utilize Libraries and Frameworks Take advantage of existing libraries and frameworks to simplify your development process. Libraries can provide pre-written code for common functions, such as controlling motors or reading sensors, allowing you to focus on the logic of your application.

Implement Real-Time Operating Systems (RTOS) For more complex projects, consider using an RTOS to manage multitasking and timing constraints. An RTOS helps in scheduling tasks, ensuring that your application meets real-time requirements.

Practice Debugging and Testing Develop good debugging habits by regularly testing your code and using debugging tools. Learn to analyze errors, use breakpoints, and monitor variables during execution. Rigorous testing will ensure that your embedded application functions as intended.

Expanding Your Knowledge

Online Courses and Tutorials: Platforms like Coursera, Udacity, and edX offer various courses in embedded systems and programming. These courses can provide structured learning and hands-on projects.

Books and Resources: Consider reading books like "Programming Embedded Systems in C and C++" by Michael Barr or "The Definitive Guide to ARM Cortex-M3 and Cortex-M4 Processors" by Joseph Yiu for deeper insights.

Join Communities and Forums: Engaging with online communities such as Arduino forums, Raspberry Pi forums, or Stack Overflow can provide support and inspiration. These platforms are valuable for asking questions and sharing your projects.
