Top 7 C++ bare-metal Projects

mt32-pi

33 1,165 2.5 C++

🎹🎶 A baremetal kernel that turns your Raspberry Pi 3 or later into a Roland MT-32 emulator and SoundFont synthesizer based on Circle, Munt, and FluidSynth.

Project mention: Something between Rpi and Rpi Pico? | /r/microcontrollers | 2023-12-10

I have just seen https://github.com/dwhinham/mt32-pi but it doesn't seem as easy to play with and well-documented as the other software I've used.

real-time-cpp

3 538 9.3 C++

Source code for the book Real-Time C++, by Christopher Kormanyos

Project mention: C++20 for bare-metal microcontroller programming | /r/embedded | 2023-04-28

Great work. I can recommend to take a look on source code repo for Real-Time C++ book (by Christopher Kormanyous) it contains some interesting examples and use cases. The book itself is also nice

baremetal

1 174 10.0 C++

ARM Cortex-M bare-metal example code in C++ and CMake build (by cortexm)
stm32mp1-baremetal

9 138 5.0 C++

Baremetal framework and example projects for the STM32MP15x Cortex-A7 based MPU

Project mention: Anyone using the STM32MP1 ? (Dual ARM cores (A7 + M4), Linux, Ethernet, CAN, USB, DACs, ADCs...) FreeRTOS on the 2nd core ? | /r/embedded | 2023-06-16

2x A7 cores for running an OS (Linux, Android) or you can run bare metal code on them too. (https://github.com/4ms/stm32mp1-baremetal)

BlueVGA

2 55 0.0 C++

VGA library for STM32F103C (BluePill) that can manipulate a screen with 28x30 tiles with 8x8 pixels each, in a total resolution of 224x240 pixels with 8 colors using a very low footprint
mdrivlib

1 14 8.3 C++

Embedded driver library using modern C++. Currently supports STM32MP1, STM32H7, STM32F7, STM32F4 and STM32F0

Being able to mark a register RW vs RO vs WO and have the compiler check your access is great. Have you also considered the case where a register bit is cleared by writing a 1 to it (or to another register)? I've also implemented my own approach for a general register class (bits and pieces stolen from various other projects): https://github.com/4ms/mdrivlib/blob/main/drivers/register_access.hh I use types for registers, rather than structs, which lets me do RegisterSetClear to handle the case where different registers set and clear a bit.
