If you're writing FreeRTOS applications in C, you're leaving safety and productivity on the table.

Nim compiles to C — same binary size, same speed, zero runtime overhead. But you get:

• ✅ Generics — type-safe queues that catch errors at compile time, not at 3 AM on a production board

• ✅ Templates — zero-cost RAII patterns for mutexes and ISR critical sections

• ✅ Range types — priority values that physically cannot be out of bounds

• ✅ Destructors — automatic resource cleanup that C developers only dream about

I built FreeRTOS Mastery with Nim to teach embedded engineers how to write real-time firmware that's both faster to develop and harder to break.

The course covers task priorities, queue-based IPC, ISR-safe communication, software timers, tickless idle, and a full capstone project — a Real-Time Sensor Hub you'll build from scratch.

If you've ever debugged a priority inversion at 2 AM or lost data to a mistyped queue cast, this course is for you.
