STM32F4 Motor Controller Firmware
Build a precision BLDC motor controller with the STM32F4 — implementing Field Oriented Control (FOC) with encoder feedback, CAN bus communication, and real-time diagnostics.
Why This Combination
The STM32F4's advanced timers, 12-bit ADCs, and FPU provide the real-time performance needed for precise current sensing and FOC algorithm execution at high PWM frequencies.
