Top 23 C Microcontroller Projects
-
MicroPython
MicroPython - a lean and efficient Python implementation for microcontrollers and constrained systems
Project mention: Broo you're still using C?? What do you use to program, a rock? LoL I can do whatever your code does, in just two lines. What do you say? Your 1947284 lines code is faster than my 2 lines code? Well, you should respect other people's preferences. | reddit.com/r/ProgrammerHumor | 2022-01-19MicroPython exists and can control microcontrollers
-
lvgl
Powerful and easy-to-use embedded GUI library with many widgets, advanced visual effects (opacity, antialiasing, animations) and low memory requirements (16K RAM, 64K Flash).
Project mention: Are there any cross-platform GUI libraries out there? | reddit.com/r/C_Programming | 2021-12-12 -
OPS
OPS - Build and Run Open Source Unikernels. Quickly and easily build and deploy open source unikernels in tens of seconds. Deploy in any language to any cloud.
-
zephyr
Primary Git Repository for the Zephyr Project. Zephyr is a new generation, scalable, optimized, secure RTOS for multiple hardware architectures.
I know that Zephyr provides a tracing library but I am unsure how to use it to profile memory (stack and heap usage) because the explanations are vague in the official documentation. Am I suppose to provide definitions to some of the functions I choose from the library in order to profile the memory? Are there any additional necessary configurations?

Project mention: Ran out of RAM on the UNO when incorporating a SSD1306 OLED. Need some advice, please. | reddit.com/r/arduino | 2022-01-13
You could try a different library, like U8G2 instead of the Adafruit lib. U8G2 has a couple different buffer modes, the page buffer mode might work for you since it doesn't store the entire display in RAM. Plus, its font support is leagues better than the Adafruit lib.

The most common languages used to write firmware for embedded devices are C/C++, Arduino (a simpler form of C), and Python derivatives like MicroPython and CircuitPython.

Though I haven't played with it myself, littlefs seems to have made a bit of a splash. If memory serves, I think ARM has backed this to some degree https://github.com/littlefs-project/littlefs
-
I checked for DAPLink, but this seems to require keil, based on what I read in the readme.
-
Scout APM
Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.
-
The Arduino core (i.e. the Arduino libraries) for the ATTiny85 (and a couple more ATTinys) is here and you can find the link for the ATTiny85 specific information a bit down the main page which, inside, includes this excelent refence picture.
-
Zephyr, RIOT, NuttX are all open source RTOSes happy about contributions

-
stm32-bootloader
Customizable Bootloader for STM32 microcontrollers. This example demonstrates how to perform in-application-programming of a firmware located on an external SD card with FAT32 file system.
Here's a bootloader "library" that might be useful. You need to add your own code to get the actual firmware image from somewhere (UART, an SD card, or whatever), and then you just pass it off to the "library" for flashing.

Project mention: Lvgl/lvgl: Powerful and easy-to-use embedded GUI library | news.ycombinator.com | 2021-10-06
seems like LVGL has direct support for the frame buffer: https://github.com/lvgl/lv_drivers/blob/master/display/fbdev...
other devices are supported too

This blog pot continues the Pico setup series and will detail how to setup a fully working debugger in VS Studio Code. Keep in mind that ultimately the steps are based on explanations from pico-debug project, and wizio-pico, but the setup is complex so I wrote a summarizing blog article. Follow along and you will be debugging your Pico C programs with the press of a simple launch button.
-
Generally you have to use HLDC or something like this to transfer data over fragmented links. This might be a good start: https://github.com/lexus2k/tinyproto
-
ubxlib
Portable C library add-on for MCU and RTOS SDKs to run data and control APIs for embedded applications with u-blox products and services.
https://github.com/u-blox/ubxlib ?
-
Gesture-Detecting-Macro-Keyboard
Glorified Bluetooth macro keyboard with machine learning (TensorFlow Lite for Microcontrollers) running on an ESP32.
Project mention: Made a Macro Keyboard which use Tensorflow Micro to detect which shortcuts to send | reddit.com/r/esp32 | 2021-06-09Demo drawing gestures GIF
-
Project mention: Introducing the Uncokeeb: a new per-finger chorded keyboard concept prototype for fast typing | reddit.com/r/ErgoMechKeyboards | 2021-11-28
Fwiw, that’s a thing, though it’s still in progress. (This says QMK, but there’s def also ZMK work somewhere in there as well.)

Project mention: LameUI - A UI Library for MCUs I have been making for past 6 months | reddit.com/r/embedded | 2021-01-23
LameUI: https://github.com/abhra0897/LameUI/tree/development

The details are on GitHub here: https://github.com/gfoot/picoprom

Project mention: How to convert an Arduino library for a mbed project? | reddit.com/r/stm32 | 2021-12-11
I don’t use mbed, but found that specific library lacking and wrote a (in my opinion) cleaner/portable C library. https://github.com/Scottapotamas/xsens-mti
