Feeling Noobish with 12F683

[Bruce]

Try this. Insert the PIC in the EPIC DIP or ZIF socket. Start meProg software, select the
PIC12F683, then click "Get Target Information" under the Program menu.

Does it return "Target device matches selected device"?

Note: Try the onboard DIP socket if it doesn't work in the ZIF.

If yes then try this;

With your meProg software, place a check next to "all" options under the main "Options"
menu.

Under "More Options" place a check by "Configuration" in Program, Verify, Read and Erase.

If it still doesn't work, look in the help file for instructions showing how to test the output
voltage of both onboard regulators.

I haven't used the old parallel EPIC for years, but I had a similar problem that was fixed by
adjusting the potentiometer that sets Vpp.

Some PICs it would program fine. Others it wouldn't.

1) In the onboard socket, it returns a match in device.

2) I still get the same error when I click the checkboxes as you suggest.

3) I checked the voltages as per the help file, and they're bang-on. Did you adjust the voltage upwards, or downwards from 13.5V when you adjusted your pot?

Mine needed adjusting up.

[picster]

No luck. Adjusted the voltage up a bit, and down a bit. The only byte this seems to be writing is byte 0. Beyond that, it's all blank (03FF). Beats me why it's giving me the error message ABOUT location 0.

Again, other pics (well, my trusty 16F88's) program just fine.

Sent an email to MeLabs - if I get a resolve there, I'll post it in followup.

Well, the MElabs folks suggested that I download the OLD version of the EPIC programmer software, version 2.46, from their website and try that to fix my problem. Lo and behold, it WORKED!!!

So if anyone else is having this issue, programming problems with the parallel EPIC programmer and the 12F683, this seems to be the fix.
