I have recently finshed programming a PIC16F84A, which is working perfectly on a PIC Test board, however I have tried to make a PIC Board of my own and can not get the PIC to work. I have port A set as inputs and Port B as outputs (wired up), And pins 14 to + v's and pin 5 to ground what else do I need to connect, and do i need an external clock, (I have the clock setting set to XT)
