Hi everyone. I hope this finds you well. This is my first project with BoostC so please be gentle with me … my comfort zone has always been assembly language, when it comes to PIC … all right, let me explain what I'm trying to do … first of all, the PIC I'm using for this project is the PIC16F877A. to drive 2 stepper motors I am using the compare module in conjunction with the TMR0; due to the 19.66 MHz crystal oscillator I have to use, TMR0 must overflow 4x times to get a 40ms period. meanwhile, the compare module will clear RC1 and RC2 when TMR1 reaches the value store in CCPRxH:CCPRx
