Helix-MP3-Decoder. Fast and easy to use fixed-point MP3 decoder with dr_libs-style API. Based on libhelix-mp3.

M5Paper-ePub-reader. M5Paper-based e-book reader supporting ePub format, with GUI created using LVGL. Currently rather a PoC than a fully usable piece of software.

STM32F4-SD-MP3-Player. STM32F4 Discovery based MP3 player using SD card as a storage, with simple GUI on HD44780 display.

IT8951-Linux-USB-Driver. C

Pico-W-A2DP-Sink. Bluetooth A2DP Sink implementation for Raspberry Pi Pico W using BTStack.

W25Q256_littlefs. Running LittleFS filesystem on Winbond's W25Q256 SPI Flash memory and playing some audio files out of it using CS43L22 chip. Loading of the files done by XMODEM protocol. Based on STM32F4-DISC1.

CH32V307-SD-MP3-Player. Port of my other project, STM32F4-SD-MP3-Player, to WCH CH32V307 board using CMake (no MounRiver IDE). Just to play around with the board and check its capabilities.

kettle-pid-controller. Kettle temperature regulator using PID controller based on Arduino Nano. Measurements taken by the means of DS18B20 sensor, Fotek SSR-40DA SSR relay used as an actuator. Current temperature displayed on TM1637 LED display.

Pure-A2DP-Sink. Bluetooth A2DP Sink implementation using BTStack, running on scrapped Mudita Pure prototype PCB.

lvgl_playground. Just a playground for experimenting with LVGL graphics library using STM32F4 Discovery board and ILI9341+XPT2046 display.
