CAN bus node pair + PID loop

Not started

Hands-on hardware project

Two ESP32 CAN nodes exchange commands/telemetry while running a PID speed loop.

Practice in the Flight Lab: Hold the wheel

Subareas

CAN (ESP32 TWAI + SN65HVD230)Logic analyzer/oscilloscope bus debuggingPID tuningControl-loop telemetry

Steps & what each needs

  1. Done when: Commands & telemetry over CAN
  2. Done when: Step response <10% overshoot, <1 s settling
  3. Done when: Writeup with a captured bus trace and one debugged issue
