A bare metal layer for the SAMD21 MCU integrated with FreeRTOS shown to improve programmer sanity.

To "install" Amslah, it is recommended that you alias amslah to the Makefile in this repository; e.g. add alias amslah="make -f /home/$USER/amslah/Makefile" to your .bashrc and then don't forget to source .bashrc. In the spirit of laziness, al also works and is shorter.

Setting up an Amslah project is easy; just create a folder with your code (e.g. main.c) and a possibly empty user_amslah_config.h configuration file. Then use amslah to build the code, amslah u to upload it, amslah ocd to open openocd, and amslah gdb to open gdb once you have openocd running. If you are debugging a non samd51 you need to edit the amslah makefile to use the correct config file

Make an issue or ask Joa(h)n and we'll be happy to help. Everything in the repo has been tested but it might not be as self-documenting as it is in my head.

Yes, please! There's always things to do in the goal of getting a friendly realtime system for the SAMD chips. If you're bored, you can participate in the upcoming rewrites in Rust, Haskell, and ATS.

Sadly that's a trade secret. Ask in person.

Extremely nonexhaustive list.

• SAMD51 support.
• Improve documentation.
• Automatic switch to DFLL48M for frequencies above 8 MHz.
