Well...actually i looked at couple of designs and made this myself......I am supplying external voltage to the board...the problem is everything seems OK when I even test the voltages....but it doesn't program anything...........
I am getting 5v on VCC and VSS is grounded.......and the PGC & PGD when they are high give me 8 volts........I am using a COM PORT, not USB
But still, i don't know why it is not programming anything........i tried programming a 24C02 chip, it didn't work.......Anyways, I think i will try to make a PIKIT2 clone or something......
I mean, even when I don't put a chip and click on read.....the programming software is reading all 00's from somewhere!!!.........and programming also, i see that data flowing (have put LEDs) but still nothing...!!
