Programming Problem PIC12F683

[tenaja]

this is usually a problem with the programmer or your hardware (i.e. pic on the pcb and connection to programmer), and has nothing to do with your compiler. Make sure if you are using any of the programming pins as i/o that they do not put any load on the programmer.

Which ZIF adapter are you using?

Which ZIF adapter are you using?

Bruce,

I'm using the 8-40 ZIF adapter. On the under side of the adapter on the board it says 03221 JMS. The cable from the programmer is plugged into the 8-18 connector and pin number 1 on the IC is lined up with Pin 1: 8-18.

Sounds like you have it connected right. If you have a 2nd 12F683 to test, and that one
won't program either, I would contact MeLabs support directly.

The only problems I'm aware of on the older 840Z 03221 ZIF adapter series were for 18F
parts which required a modification for AVdd connections to pin #7.

One other thing to check... if you've already programmed the chip once. Make sure your programmer is set to high voltage programming.

Problem solved. I downloaded Beta Software for EPIC™ Programmer, including the update for the firmware and the programmer works great now. On the download page, there is the following statement "It does not support the advanced command-line switches of the paid upgrade." I don't know what that means for me.
