Sensorless BLDC Driver

Sensorless brushless motor controller using PIC18F1230 (XC8)

Use only PIC and FET
PWM
ADC

Features(Implemented)

Open-loop drive.
Closed-loop drive(seamless transfer from open-loop).
Closed-loop lock detection(back to open-loop).
Speed control by EUSART input.

Variables(Implemented)

Direction of rotation
Open-loop duty
Open-loop initial speed
Open-loop acceleration
Open-loop to closed-loop speed
Closed-loop speed
Closed-loop acceleration
