I have the HPWM working at 3.6kHz and I want to use that signal to set the interrupt flag on the rising edge. The signal coming out of the HPWM is fine when I do not have it wired to PORTB.0. Are my registers set correctly to make PORTB.0 an input and the others an output??
TRISB = %00000001 ' Set PORTB to all output, except for bit 0
That's the only thing I can think of that would be messing up the signal when I connect the two pins (CCP1, pin 17 and INTB0, pin 40). Any suggestions?
RB0/INT0 is PIN 33.... PIN40 is RB7 wich you set as output, this short your signal to ground.Quote:

wow, i don't know what to say. I feel like an idiot... b/c in a way, i am an idiot for doing something like that. I could have sworn I got the diagram right but I guess not. If that was my problem the whole time, then let me switch it (to pin 33) and see if it works.
those things happens. With eyes open it can help to read datasheet LOL!
