Hello everyone!
I've a problem regarding the PICPgm programmer. I've built the LVISP Programmer. PICPgm detects the programmer but not the PIC. Ive tried two pics uptil now and they are PIC18f4550 and PIC16f877 but none could be detected. I've checked the connections again and there seems to be no problem. One thing that i've also done is that I've connected a 33pf cap with a 100 ohm res in series to gnd with the PGD line and a 33pf to gnd with PGC line but this also didn't help.
The RB5 pin is also connected to gnd via a 1K res as mentioned in the circuit. What could be the possible fault? please help me out!
Thanks in advance
