Open source STM32 MCU programming toolset

Open source ARM Cortex-M microcontroller library

Advanced fault backtrace library for ARM Cortex-M series MCU | ARM Cortex-M 系列 MCU 错误追踪库

CMSIS-DSP embedded compute library for Cortex-M and Cortex-A

An efficient and secure microkernel built for ARM Cortex-M cores, inspired by L4

A dedicated performance counter mainly for micro-controllers. For Cortex-M processors, the Systick will be used by default. The `perf_counter` shares the SysTick with users' original SysTick function(s) without interfering with it. This library will bring new functionalities.

virtual debug pod for RP2040 "Raspberry Pi Pico" with no added hardware

A tiny Linux-like real-time kernel optimized for ARM Cortex-M chips

UART based embedded shell for embedded systems. Intended to be used for learning, experimenting and diagnostics.

Blackmagic Wireless SWD Debug probe hosted on esp-idf SDK (for ESP8266) with UART on Telnet port and HTTP using xterm.js

TNeo: a well-formed and carefully tested preemptive real-time kernel for 16- and 32-bits MCUs

2.11BSD-based Unix-like OS for STM32 and PIC32 Microcontrollers

Dynamic linker for Cortex-M MCUs

DEPRECATED, use our successor library https://modm.io instead

Framework for building Arm Cortex-M "FLM" style flash programming algorithms.

DoraOS 是我个人所写的RTOS内核，结合FreeRTOS、uCOS, RT-Thread, LiteOS 的特性所写，取其精华，去其糟粕，本项目将持续维护，欢迎大家fork与star。
