    Default Need help with config

    I am trying to set up internal asc and MCLr options in the config of my code for a 16f688. The data sheet has the config bits for all of this on page 100. Is there an easy way of setting this? I tried config=%11001111000100 nut this did not work. I got a syntax error. The posts that I have read seem to set each function in the config individualy. Can some one point me in the right direction.
    Thanks

    Hi,

    I may have mis-understood your post but if you're just trying to set the configuration bits try:

    for PM Assembler:
    Code:
    @ device INT_OSC, MCLR_OFF
    Is this what you're after?

    Kind regards

    Rob

    Yeah, that's a good thread - should've posted a link to it myself!

    I have read the suggested post again. All examples in this post appear to set each option in the config seperatly, ie pic type, mclr, pwrt as seperate comands but the datasheet for the 16f688 shows a config register called 11.1 (page 100) with each option as seperate bits either set or cleared. Can I just send this as a binary string (or hex equivelent)? if so how?

    It never worked that way for me, every newbie reads that and tries it,(I did) and it has never worked that I heard of. You can string the commands together though, like so:
    Code:
    @ __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_ON & _MCLRE_OFF & _BODEN_ON & _LVP_OFF & _CP_ALL & _DATA_CP_ON
    The data sheet shows you what happens in those registers, but you can access them only at program time and require you to use the proper syntax as shown in Melanies post.

    Ok that clears that up a bit. I guess its more reading and experementing. Thanks

    I have tried some of the examples in the suggested post but I get compile errors.
    Here are some of what I have tried

    @ CONFIG FOSC = HS
    opcode expected instead of config

    ASM
    CONFIG OSCS=OFF ; Oscillator switch OFF
    ENDASM
    Same error

    @ __CONFIG _CONFIG1H, _OSCS_OFF_1H & _HS_OSC_1H
    Same error

    I am using Picbasicpro with microcode studios

    Looks like you're still stuck...

    I need some information... are you using Microchip's MPASM or MeLab's PM as the Assembler? or don't you know?

    If you don't know, then I'll have to install MicroCode Studio which I don't ever use and see what the default's are when trying to compile for this chip.

    Oh, finally, what version of PBP are you running?

    I thought that MElabs PBP was the compiler. I have ver 2.5.

    SO ...

    THIS
    Code:
    @ __CONFIG _CONFIG1H, _OSCS_OFF_1H & _HS_OSC_1H
    doesn't mean ANYTHING with a 16F688 ...

    Capito ???

    Does this need to be in assembler or in straight basic

    Default Use Mpasm

    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:

    Code:
    @ __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:
    Code:
    __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _CP_OFF
    just put a semi colon at the beginning like this:
    Code:
    ;__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
    Code:
     @_config MCLR OFF
    or
    Code:
     @_config MCLRE OFF
    depending on if pm or msasm is used.

  19. #19

    Default oops

    thats actually
    Code:
     @_config _MCLR_OFF
    or
    Code:
     @_config MCLRE_OFF
    the hs osc you were trying should be
    Code:
    @_config _HS_OSC
    or
    Code:
    @_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)
