Okay, what am I doing wrong?! I've got an Olimex PG-2C. I place a PIC16F628 in the programmer socket and it programs and verifies just fine, using IC-Prog v1.05. When I connect the ICSP lines to the PIC and try programming it fails. Pin 1 of ICSP (Vpp) is connected to PIC pin 4. Pin 2 of ICSP (Vdd) is connected to PIC pin 14. Pin 3 of ICSP (GND) is connected to PIC pin 5. Pin 4 of ICSP (RB7) is connected to PIC pin 13. Pin 5 of ICSP (RB6) is connected to PIC pin 12. That is it. I don't have anything else connected to the PIC; the ICSP lines are connected right to the PIC pins with micro clips. I've verified voltage levels, continuity, and correct connections MANY times. Ugh, Mike |

What are you doing with PGM/RB4 - you probably need to ground it. Also, at some point you may want to clear the LVP bit in the CONFIG word. There could be programmer issues but I have been caught with these 2 items before. --- In , "upand_at_them" <upand_at_them@y...> wrote: > Okay, what am I doing wrong?! > > I've got an Olimex PG-2C.

Microchip's datasheet for the 16F628 says it supports ICSP. Mike --- In , Hasan Arslan <harslan74@y...> wrote: > PIC16F628 have not ICSP feature. you must be use PIC16F628A series... |

Yes, 16f628 support ICSP and i say that ive ever used this features many times.

have not ICSP feature. you must be use PIC16F628A
series...
nonsense, all F PICs (and nearly all others) are ICSP
programmable.

Yep - the original poster was talking about 16f628, as was I. Been spending too much time with the 12c & 12f family lately. dwayne -- Dwayne Reid <> Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 20 years of Engineering Innovation (1984 - 2004) .-. .-. .-. .-. .-. .-. .-. .-. .-. .- `-' `-' `-' `-' `-' `-' `-' `-' `-' Do NOT send unsolicited commercial email to this email address.

I have to ask the question....NOTHING else connected to the PIC? A crystal
and caps, a bypass cap and a pullup resistor on pin 4 are probably necessary. You don't need many parts, but I believe that PIC must be basically operational.
