Does the external clock value and the clock value that you had program to the PIC must match?
I have programmed a PIC 16f877A using Flowcode and set the clock speed in 3276800. I load the program to the PIC and verify and it was successful. After then I interface the pic, I connected the supply vdd, vss and a 4MHZ crystal oscillator and the leds but the PIC won't run. The leds won't light. What seem to be the problem can you help me?
