    The minimum You HAVE to read is ... BOTH ...

    A look to Microchip Assembler is not too much nor, if used !!!

    ...

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...
    ************************************************** ***********************
    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    To help a person who, after exhausting other options such as reading the datasheets or the manuals, or after doing a number of tests, try, experiments, etc. is just plain stuck and needs a nudge to figure out a problem.
    Doesn't look to me like you've done any of the above...

    PBP handles this for you. It's very easy to verify.

    Compile this for a 12F508;
    Code:
    Main:
        HIGH 0
        pause 500
        low 0
        pause 500
        goto Main
    
        End
    Now simply open the .LST file, and look for it.

    ORG 0 ; Start at 0
    movwf OSCCAL ; Set oscillator calibration

    Look in your PBP manual, section 2.5.1, PICmicro MCU Specific Issues.

    Hi Bruce,
    My Gosh!
    I never opened a .lst file before, I opened one, from one of my simple programs which just outputs serial strings at 4 different baud rates to test serial inputs, and wow over 32000 lines of code! What really is astounding is that the pic can process it all so fast.

    Yup but you'll notice many IF/IFDEF/IFNDEF wich are not process by the PIC but by the assembler. if you want to have something a little smaller, open the .asm file. on a 18F452 the single line...
    Code:
    hserout ["hello"]

    the interesting stuff is HSEROUT?C. now open the .MAC file, it produce...

    HSEROUT?C macro Cin
            MOVE?CA Cin
            L?CALL  HSEROUT
        endm
    HSEROUT_USED = 1
    
    
    	LIST
    so you know that it store each character (C) in Wreg(A), and then call the HSEROUT sub.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
