Anyone want to share some embedded projects they have done?

• jtagstudy

  1 0 3.6 C

  A project to understand JTAG by bitbanging some of its functionalities on the AVR architecture.

Not super interesting but I recently implemented some basic JTAG functionalities on AVR via bitbanging: https://github.com/Thiird/jtagstudy

• uni-STC

  3 23 7.6 C

  SDCC support + HAL + drivers for STC 8051 MCU

I know it's considered awfully weird, but for some reason, I got hooked on STC MCU. Recently, I decided to structure what I had been developing here and there and it took the shape of an open-source HAL.

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• stcgal-patched

  3 16 4.4 Python

  stcgal patched to support STC8G, STC8H, STC8A8K64D4 and STC32G.

And because STCGAL's author seems to have lost interest in his "baby" and didn't care to support STC's most recent MCU, I ended up forking it and taking over its maintenance. I don't like Python at all, but STCGAL was there, I need its functionality, and it's less work to maintain it than to start over, so...

• led-controller

  3 3 0.0 C

  Software for PIC32MX330F064H LED (cube) controller. The controller can be used for driving 256 RGB LEDs with a color-depth of 8 bit.

Currently working on a bootloader for my LED cube controller boards. It's still work in progress.

• BTMSrev1

  14 1 2.7 C

• 400hz-Driver

  6 1 3.8 C

  A lazly built circuit for driving LED xmass lights at 400hz to reduce flicker.

• speki

  1 1 0.0 C

  Ein Audioplayer mit "Speki" auf dem CARME-M4-Kit unter Zuhilfenahme der diskreten Fourier Transformation. Erstellt als Projekt für das Modul BTE5053 Hardwarenahe Softwareentwicklung. (by NikLeberg)

Not per se in my free time but for my bachelor I've build together with another guy a simple music player. We were given a STM32F407IG based kit with display and some control knobs. As in another class we learned the fourier transformation we decided to implement a discrete FT for audio. It reads and decodes WAV files from a SD-Card, calculates its spectrum and displays it together with album cover/title/interpret and progress. It looks pretty I think. :) github.com/NikLeberg/speki

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• neorv32

  77 1,423 9.9 C

  :rocket: A tiny, customizable and extensible MCU-class 32-bit RISC-V soft-core CPU and microcontroller-like SoC written in platform-independent VHDL.

Maybe not a classic (whatever that means...) project, but I am working (together with others) on a RISC-V microcontroller for FPGAs: https://github.com/stnolting/neorv32

• estdlib

  4 41 9.6 C++

  C++ Standard Lib adapted to embedded environments

  

I wanted to use standard c++ libraries for embedded without all the saddling of dynamic allocation, so I made https://github.com/malachi-iot/estdlib. I use it in all my embedded projects
