My P16PRO40 PIC-programmer
The P16PRO40 is a programmer for
8-pin, 18-pin, 20-pin, 28-pin and 40-pin PICs. I chose to build this programmer
because the hardware is easy to construct and the software is free. The
programmer is connected to the parallel port of the PC using a short cable.
The programmer is powered from an external power supply.

The P16PRO40 diagram
was created by Bojan Dobaj. The main components are a 40-pin ZIF socket
(not mandatory), power supply components, three transistors, three LEDs
and a 74LS07. The programmer applies 13 V to the PIC during programming.
The external power supply must deliver at least 16 V DC or 12 V AC. I've
employed a 24 V AC supply which was originally used for powering a light-chain
for a Christmas tree.
I am using Nigel Goodwin's free
version 1.91. The software is running under Windows and supports programming
of 16F83, 16C84, 16F84, 16F627, 16F628, 16F873, 16F874, 16F876, 16F877
and other common PICs.
