This is my first attempt at a PIC project. I'm using a TOP2004 with a PIC16F877A chip. My problem is that I cannot figure out what the configuration bits should be set to in the top programmer software. Mostly it is the FOSC0 and FOSC1 that I am not sure what to do with. I want to use a 4Mhz crystal with my PIC... besides that I am just trying to blink a single LED from PORTB bit 0. Can anyone help??
