Very Simple ICSP Programmer

[sandeep]

Hi guys,

I have been using this simple programmer.. why pay big bucks for a PIC programmer when this one costs just cents! In fact I have stopped using my 'other programmer' all together now.

All you need is:
three 4.7k Resistors,
a few wires (1m)
9 pin d-connector (female),
and a 5 volt dc supply.

I have used it on 16F84, 16F62X, 16F87X chips without problems.

To make it:

TXD (3) ------[4.7k]-------VPP

GND (5) --------------------VSS

DTR (4) -------[4.7k]------DATA

CTS (8) ------------------DATA

RTS (7) -------[4.7k]------CLK

Numbers in Bracket are the connections on the 9-Pin D-Connector.

I have made up a small PCB to mount the resistors on but... you could just solder them in line to go cheap.. Just be carefull they dont short out. If anyone wants the PCB footprint I can post it.

Then just put your PIC into a breadboard, connect your 5 volt supply to VDD/VSS, and away you go.

hi!!!!!!!!!
can u please send the pcb layout &some more details to programm
the pic
its argent!!!!11111
also which type pic r compatable with the such programmer?
im new here
expecting u r kindaa response
i l be more happy u send softwares so that i m able to make pcb layouts

OR...and I just might be a little bit crazy here...
If it's so argent, just go out and buy a PICKIT2.
Microchip supported, already complete, done, done and done...
