Operating system for AVR microcontrollers

• Fixed-priority pre-emptive scheduling
• Process aging to avoid starvation
• Pre-emptive spin-lock mechanism
• Relatively small and simple to learn from

Supported devices

• ATMega32

Supported compilers

• GCC (AtmelStudio)

How to use it?

Install gcc-avr and python package pyavrutils by running # pip install pyavrutils Config is placed in build.conf. Run py build.py. Check main.c for examples.

Known issues

• It is unsafe to create processes, mutexes, or calling malloc/free when the system is running (fix: add system-side and pre-emptive save allocation mechanism)
