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.
