I built a small real‑time operating system for ARM Cortex‑M as a step‑by‑step guide to teach how an RTOS is built from scratch.
The kernel starts from a few hundred lines and grows through context switching, scheduling, interrupts, and simple IPC — all explained in a minimal, readable way.
If you want a practical, tiny example that shows exactly how to write an operating system for microcontrollers, this project is designed for that.

Genuinely impressive. The memory management section alone is worth the read.
What was the hardest part to get right?
