Feeling Noobish with 12F683

[picster]

Ok, this is getting to me.

very simple test program:

CMCON0=7 '00000111 - comparator pins configured as I/O
ANSEL=0 'all I/O is digital
OSCCON=96 'internal 4mhz clock 01100000
TRISIO=40 '101000

led var GPIO.4

CLEAR

start:

led=1
pause 500
led=0
pause 500
goto start

compiles fine (no duh)

Using pbp 2.46, the parallel EPIC PLUS programmer, ICSP harness... erases fine, confirmed blank.

I get a "code programming error at 0000"

Upon "verify", it shows the following message:

"Configuration verify error at 0000. 0FFF should be 00F4. Continue verifying?"
The rest verifies ok if I click YES.

I have verified that I can program a 16F88 right afterwards, with no issues.

What the heck ?

Any suggestions?

Do you get the same error if you try programming the part in the EPIC DIP socket?

[picster]

Haven't tried it... I'll give it a shot and let you know.

Same results in the ZIF socket and in the on-board socket.

Any other ideas? If the 16F88's wouldn't program, I'd at least have a pattern.

Also tried another 12F683, same result.

I'm sure they'll get you up & going.

Can you post your config seetings from the inc file and the generated hex from you compiler?

[picster]

Can you post your config seetings from the inc file and the generated hex from you compiler?

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's the hex generated:

What version of software/firmware for the EPIC PLUS are you running?

[picster]

using meProg 3.30 - is there firmware for the Epic Plus parallel?
