bldc-driver's Issues

Fix Hall sensors input

Looks like hall sersor input is wrong.

Check if rotating sequence is correct
Check if interrupts are working correct
Make hall input scheme on pcb

Rotor speed measuring

Compute rotor speed using three digital hall sensor signals.

Write function for computing speed based on hall sensores
Measure speed using microphone
Find out physical angle between hall sensored

Current limiting

Add current limiting to protect the motor.

Constant speed PID control

Change PWM signal to hold constant speed. Should be easy for block commutation.

Complete speed measuring #7
Write PID controller
Correct coefficients

DC bus current sensing

How to measure dc bus in a 3-phase half bridge inverter.

Measure using shunt + op-amp
Measure using Hall Effect-Based ACS712

Sensored block (trapezoidal) commutation

3-phase inverter

Hall sensor signals to switches

600v Driver software. Need help

I need stm code to drive 600v powerboard and motor, with torque settings, speed settings. Cna you help?
