Open source ARM Cortex-M microcontroller library

Open-Source Firmware for ZY12PDN USB Power Delivery Trigger

A tiny external monitor for PC using STM32 and ST7789. Connects to PC over USB and displays the captured screen on ST7789 (240x240) display.

MakeCode UF2 bootloader for STM32 Blue Pill

IoT program for Arduino Uno / STM32 Blue Pill (libopencm3) that reads BME280 temperature + humidity + altitude sensors, via I2C or SPI with DMA and multitasking. Sends sensor data to Sigfox via Wisol Sigfox module on UART. Runs on cocoOS task scheduling library http://www.cocoos.net
