PIC Programmer
PIC programming is useful as it allows you to build electronic hardware and to implement software into the
hardware at little cost and relatively easily.
Note: It appears this design is simular to the COM84 Programmer.
A possible PCB solution for this is provided below, I have not yet built this as I still use a stripboard based version which I believe is equal to and possibly smaller in size.
Programmer for PIC 16C84, 16F84, 16F627, 16F628
Searching the internet I have been unable to find a programmer as simple as this one which was built from a schematic ages ago, if anyone does know the source then they will be acknoledged as the source is still unknown. This programmer is the simplest I have seen utilising no external power surply and only 6 components. It connects to the computers serial port.Note: It appears this design is simular to the COM84 Programmer.

Using the Programmer
ICProg - http://www.ic-prog.com/
Works well for programming the 16C84 and 16F84 but fails with the 16F628.
WinPic - http://people.freenet.de/dl4yhf/winpicpr.html
This programing software with a few config changes works well for all PIC's using this programmer.
Options tab - raise Vdd before MCLR=Vpp has to be enabled.
Device, Config tab - Low Voltage Programming has to be disabled (could possibly leave this enabled from the start).
Programmer Type - JDM and COM84 should work.
Sample Code and How to use HI-TECH PIC-C with the 16F628 are provided on the PIC ASM & PIC-C pages respectively.
All Schematics created using the really good Eagle Program
