pico-bldc

RP2040-based BLDC motor controller that I designed for our 2024 PiWars robot, Firebot.

It controls four BLDC motors with field-oriented control and provides an I2C interface so it can be controlled by the main processor of the robot.

I wrote up the build of the controller on our blog, from slow-and-janky in Python through to controlling 4 motors from one core in C:
