Another 2.60 worry

[HenrikOlsson]

Hi,
There IS a standard, basic, working most of the time configuration fuse setting already setup for each and every chip that the compiler supports. You don't have to set them in your code if the default is OK.

If you wan't to see how they "work" and what they are simply open the .inc file for the specific target you're compiling for, it's located in the root of the PBP folder. For the 16F886 the fileneme is 16F866.INC and looks like this:

        NOLIST
    ifdef PM_USED
        LIST
        include 'M16F88x.INC' ; PM header
        device  pic16F886, intrc_osc_noclkout, wdt_on, mclr_on, lvp_off, protect_off
        XALL
        NOLIST

    else

        LIST
        LIST p = 16F886, r = dec, w = -302
        INCLUDE "P16F886.INC" ; MPASM  Header
        __config _CONFIG1, _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _LVP_OFF & _CP_OFF
        NOLIST
    endif
        LIST

Now, the @ DEVICE statement is used when you're using PM as the assembler and the __CONFIG (note two underscores) is used when you're using MPASM as the assembler. If you're Win7 you can't use PM which means you're using MPASM which means @ DEVICE is the wrong "command".

In order to find out the "names" of the various fuses go to your MPASM folder and open the P16F886.INC file, at the end of that file you'll find this:

So, to change the CONFIG fuses you have two options:
1) Edit the 16F866.INC file in the PBP folder to have the CONFIG you want/need. Do make a backup of the original file first.
2) Comment out the CONFIG from the 16F866.INC file and instead put them in your code.

Rightio, I opened the M16f88x.inc file in the PBP directory.
That first example you gave does not exist anywhere in the file??
This is getting all too hard..I'm gunno go play soliraire.

I do understand that I can edit the first example you gave and make it into a new default that suits me.
But, as I said, it ain't in there.
