Hey guys, I've decided to start a little guitar tuner project, using assembly with a PIC16F877. I have the circuit set up, so my guitar output is essentially a square wave that I can go into the pic with. My DMM is reading the right frequencies and voltage there, so I know that's good.
My issue is, I'm really green to this stuff, so I'm not sure how to start with the programming and input. Is there a way I could increment a timer every time the input is high, and compare say 20 input pulses with the external oscillator cycles in the time frame it took? Or is there an easier way? Any help would be appreciated. Thanks!
