Help with programming a PIC16f877A with Pickit2 Answered
I am having a really hard time programming a PIC16f877A with a Pickit2 programmer or a homemade serial programmer. I have tried several ICSP interface circuits but neither programmer can read the microcontroller.
I have been able to program other PICs with each programmer without any problems. I am beginning to think that I just have a bad chip. Does anyone have experience using Pickit2? A step by step breakdown would be extremely helpful.
Can anyone suggest a good interface for the PIC16f877A? I have tried connecting the pins directly to the programmer. I have also tried using pullup resistors on MCLR, and used a schematic for ICSP that I found on the Microchip website.
One thing I have yet to try is powering the chip with an external power supply, Would this method work?
