16f84a programmer

hello

When I needed a 16f877A programmer , I searched the web..
Yes I found many , but most of them are complex ( or at least not simple )

But I have found this programmer from my friend , it's very simple :



to use this programmer with PIC16F 84A just use the
following connections :

NB I: pins 4 & 8 in the Female rs232 are connected together.

NB II : the +ve of the capacitor is connected with the -ve of
the zener diode

NB III : tested on 877A & 84A only , I do not gurantee the
programmer for any other MCU .

NB IV :
tested with IC-PROG ==> no problems
tested with Win-Pic ==> use the folllowing options :
- Broun Out Reset => Enable
- Low Voltage Programming => Enable


have phun :D
