Need help with config

[Archangel]

Hi Darrenmac,
Microcode Studio defaults to using the PM assembler, to use MPASM you have to tell it to, here is how: 1.start micro code studio 2. click on the word VIEW at the very top left. 3. Click on Compile and Program Options, and it will open a box which has at it's top, 3 tabs, notice on the first tab an empty box which says use PBL, but do not put a check there, click the center tab marked assembler. You will see an empty box marked: USE MPASM. Put a check mark there and close the box. You are now using MPASM as the assembler.

So do I use
@ MCLR_OFF
or
MCLR_OFF

Hi Darrenmac,

If you have not changed your settings as per Joe S's last post then you are using the PM assembler as this is what Microcode Studio defaults to. In this case see Post#2 in this thread.

If you have changed your settings as per Joe's last post then you need to use:

@ __CONFIG _INTOSC & _MCLRE_OFF

Cheers

Hi Darrenmac,
Now after you do all this you will get a compile error telling you you are overwriting the configs . . . that's because you are. In your PBP directory you will have many files with the suffix .inc and the filename will be the number of your PIC. Open it and you will see the following code:

__config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _CP_OFF

just put a semi colon at the beginning like this:

;__config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _CP_OFF

save the file and then no more error. This config is the " DEFAULT" config setting in case you forget to put in any config so your program will still work sometimes.<br>
Now, why go through all of this? Well suppose you DO NOT want to use the internal oscillator? The DEFAULT configs will not work with a crystal or resonator or EXT oscillator, so do it now and get used to setting the fuses early into your adventure into PIC Magic

Still having issues, I think that I am going to be better off by setting them in the programmer. At least I can get it to work. Thanks for every one who has tried to help

Setting them in the programmer works. but if you ever want to just program a chip from a saved hex file, your going to get bit in the behind if you don't remember what settings you used in the programmer. its really a two step operation. PBP is the basic compiler, it creates an assembler file. then either pm or msasm compiler assembles that into your hex file that gets programmed into the chip. the fuse names/settings are written into your basic program but are dependant upon which assembler you use. The assembler is what uses these config commands. PBP passes these to the assembler with the @. so your line would be either

 @_config MCLR OFF

or

 @_config MCLRE OFF

depending on if pm or msasm is used.

[nomad]

thats actually

 @_config _MCLR_OFF

or

 @_config MCLRE_OFF

the hs osc you were trying should be

@_config _HS_OSC

or

@_config HS_OSC

someone please check my writing, i can't see the _'s during preview on here. (not at home and using my phone lol)
