I have a big problem programming 16f876a-i/sp on an epic programmer. The epic manages to program PIC16f877A-20 no problen.
I have a very simple circuit Allowing ICSP drawing attached shows how it is connected.
power is supplied to the chip from a very stable 5V supply.
The ground from the epic is connected to the ground on the chip.
The clock and data lines for programming are connected correctly.
I have a 10k resistor from 5v connected to pin 1 via a 1n4148 to prevent the chip erasing.
The programming voltage is taken directly to pin 1
I have two oddities, the first is the 10k resistor and the diode, maybe these are not so perfect and also the 16f876a-i/sp is not listed in my epic software so I can only select 16f876a.
