Hi i wrote a program for the 16f676 and programmed it (ICSP) onto my board. I had some timing issues so i reworked the program and now it wont program again. (I am using the EPIC programmer)
I thought it might be the chip or the programmer, so i tried another board. it programmed! but the timing still wasnt quite right. so i changed the program again, and this pic wont program. Its not an otp so.... any ideas????
