Classic PIC Programmer
Description:
This is my own version of the classic PIC 16C84/16F84 programmer. The design is originally by David Tait. I've made a few changes, redrawn the schematic and done a board layout. All the files you will need are linked below, including software you'll need to operate it. The software is not by me, I'm just including it for your convenience, and you should follow any usage requests the authors have made.
Application:
PICs are small microprocessors containing RAM, ROM, and some peripherals. Almost no other parts are required to make a complete “embedded system”. They are readily available and well supported by the manufacturer, third party developers, and most importantly, users. This has led to their immense popularity.
Assembly:
The PC board design is fairly straightforward and can be made by laser printing to special paper or a page from TIME magazine, then ironing the image onto copper-clad board, then etching with ferric chloride. There are a few jumper wires. The power source needs to be at least 15 volts. A 12 volt DC adapter usually produces about 17 volts, so that's a good choice. Two 9-volt batteries in series will work too. Solder directly to the PC board or use a connector that mates with your power source. Pay attention to the direction of the voltage regulators because the plastic regulators are backward from the tab type. Substitute Japanese or European generic equivalents for the transistors and diodes, but remember that the pinouts will be different. A right angle PC mount DB-25M connector is specified, but a conventional solder-cup DB-25M connector works, see the picture how I did it.
Operation:
The programmer connects to the parallel printer port of your computer and requires external power. If you want to program a PIC you'll have a hex file created by your assembler or created by someone else(see my propeller clock). You will also need to drive the programmer with some software. Here are programs
