Project mention: At what point would you consider using an RTOS? | /r/embedded | 2023-06-26

Lately I have been working with interrupt driven task frameworks on ARM Cortex-M. Basically they are using the ARM NVIC as a task scheduler. Examples for C/C++ include this one: Super Simple Tasker. For Rust there is RTIC. Both are based on similar ideas of using NVIC as scheduling engine. Very efficient resource-wise but use a somewhat different programming paradigm than traditional RTOS threads.
