C for microcontrollers and memory

Module goal: write C that works with bits, registers and memory safely on a microcontroller.

Status: alpha (experimental) · Approximate time: 210 minutes

Every lesson has content, examples you can run on your computer, practice with a solution, a check for understanding, and a lab. The course code runs and has been checked on a computer; the on-board labs are still waiting for a teaching trial.

End-of-module checkpoint

• Read the SDK’s 06_raw_register_access.c example and explain the read-modify-write step, line by line.
• Identify whether a variable in an example program lives in the stack, the heap, or static memory.
• Read a real task’s stack counter on the board, and judge with a calculation whether it is still safe.
• Pass every test in the 03_ring_buffer.c exercise, and explain who owns the data in the buffer at each point.
