Feeling Noobish with 12F683

[mackrackit]

I use the config settings via meProg options, not in the file itself, and have them set as follows:

Oscillator: INTOSCIO
Watchdog Timer: Disabled
PowerUp Timer: Disabled
MCLR Pin Function: Reset
Brown-out Detect: Disabled
Internal External Switchover: Disabled
Fail-Safe Clock Monitor: Disabled
Code: Not Protected
Data EEPROM: Not Protected

Here is what you hex says

Almost matches. I do not have you setup. Is there a way with you programmer to set the fuses from the inc or in the code?

I am just guessing again

Darrel,

I have the item you noted checked, and upload config from file UNchecked. I don't have "Program Fast" checked - but I doubt this would be the problem?

Maybe a bug in the 683 include file? Should I post it for comparison to yours? I haven't edited it or anything, but maybe it's a 2.46 undoc'd bug or something?

Dave,

Not sure about how to set the fuses in code, I've always done it from the EPIC programmer's chip configuration settings window because it's simple.

I'm doing the PICBASIC in microcode studio - so if there's an easy way to set these switches there, I suppose I could try it (but right now I wouldn't know how).

This is the best explanation of how to set the fuses in code space.

As usual, pay close attention to the post from Melanie and Mister-E.
Is there a way in the EPIC to turn that option off? I have not used the EPIC.

I'm going to try installing the latest MPLAB IDE. I'm using it as the assembler. My current version is 7.3, so we'll see if the new one makes any difference.

Is there SOMEONE out there who can try my program on THEIR EPIC Plus with a '683 and see if it works for them?

MPLAB updated, no change in the outcome. Still the same message.

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.
