Capture and Compare with PIC16F877A

PIC16F7877A prototype board

The PIC16F877A microcontroller comes with a Capture Compare PWM (CCP) module which utilizes its 16-bit Timer1 module to generate or count pulses, among other things. I have already covered how to generate PWM in my previous tutorial. This time, we will look at how to implement capture and compare with …
