16F886 (illegal opcode CONFIG1)

[MOUNTAIN747]

I am adding DT’s INT_INT to an existing and functioning program I assembled with PM. Now using MPASM I am having problems with the config’s.

16F886, MicroCode Studio Plus, MPASM, internal osc @8Mhz

ERROR[122] (illegal opcode CONFIG1)
I found an example by mackrackit from 10JUNE,2010 and tried his example but it failed also.

I’m using:
@ __config _CONFIG1, (_INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_OFF &_LVP_OFF & _CP_OFF)

OSCCON = %01110000
DEFINE OSC 8

I’ve tried with and without the comma (,) after CONFIG1, I’ve tried with and without the brackets, and the error always says “illegal opcode CONFIG1.” I've used CONFIG1 in upper case and lower case, no go!

Its got me stumped,Comments please!

Are you sure you have the 16F886 selected in the Microcontroller dropdown box of MicroCode Studio?

[MOUNTAIN747]

16F886 is in the dropdown window! yep!

[Darrel Taylor]

Under View > Compile and Program Options > Assembler tab ...
Is the path above the Find buttons ... C:\Program Files\Microchip\MPASM Suite or C:\Program Files (x86)\Microchip\MPASM Suite for 64-bit systems?

If not, click the Find manually button and point it there.
MicroCode Studio will usually find the wrong path if you have more than one MPASMWIN on your computer.

[MOUNTAIN747]

My path is C:\Program Files\Microchip\MPASM Suite. Yes, I am aware of this Gottcha! I had to deal with it a few years ago. I double checked it to make sure something didn't revert back to the Wrong MPASM. This just doesn't make any since. I even tried to use @config (0x20F4) but that didn't work either. I also checked my spellling four times to make sure... what else?

[MOUNTAIN747]

Darrel, On the assembler tab page, what is INH8XM, INH8XS, and INHX32?

[Darrel Taylor]

Those specify the .HEX file format and should not be changed.
Later versions of MicroCode Studio have removed those options.

Please send me your .LST file after a failed compile.

[MOUNTAIN747]

You'll have to explain how I send it to you. I can't use Private Message.

Although the line you showed in post #1 had 2 underscores in __config and had a space after the @ sign ...
The .lst file shows that the actual line had only 1 underscore and no space.

It also shows that the __config line in the 16F886.inc file hasn't been commented out.

[MOUNTAIN747]

OK, so once I commented out the __config default line in the PBP INC file it compiled without errors.

As always, Thanks Darrel
