BLDC Motor Control using PIC16F877A Microcontroller

[Okba_]

Hello,
This is a project for controlling sensored brushless dc motor (BLDC Motor) using Microchip PIC16F877A.
This motor is a 3 phase motor, it has three hall sensors to detect its position in order to generate the appropriate signal to the three phase bridge as shown on the attached circuit schematic.
The following video shows the working:

Hello

Is it possible to see the speed of the motor?

Thanks

Yes we can since we can compute number of pulses but this operation needs more complicated code.
