    Now that I am declaring T2CON IN HEX that part is working, and I am not getting any more bad token errors. I see what you meant about the many warnings... Looks like I will have to spend more time debugging...

    Be carefull with the spacing of ASM statements.

    In particular ... (quoted from Post #6)
    Code:
    ASM
INT_LIST macro ' use the format IntSource, Label, Type, ResetFlag? 
INT_Handler TMR1_INT, ReloadTMR1, ASM, no
INT_Handler TMR1_INT, _MATHhandler, PBP, yes
endm
INT_CREATE ; Creates the interrupt processor
ENDASM
    Should be ...
    Code:
    ASM
INT_LIST macro ; use the format IntSource, Label, Type, ResetFlag? 
    INT_Handler TMR1_INT, ReloadTMR1, ASM, no
    INT_Handler TMR1_INT, _MATHhandler, PBP, yes
    endm
    INT_CREATE ; Creates the interrupt processor
ENDASM

    Talking

    THANK YOU DT! I just came home from a strenuous day at the hospital...and that piece of information was very uplifting...I thought I would be banging my head for at least a month trying to solve those...

    IN CASE ANY OTHER NEWBIES ARE READING, HERE IS THE LAST PIECE OF CODE THAT HAD WRONG INDENTATION/SPACING AND HAS BEEN CORRECTED:

    ASM
    ReloadTMR1
    MOVE?CT 0, T1CON, TMR1ON ; 1 stop timer
    MOVLW LOW(TimerReload) ; 1 Add TimerReload to the
    ADDWF TMR1L,F ; 1 value in Timer1
    BTFSC STATUS,C ; 1/2
    INCF TMR1H,F ; 1
    MOVLW HIGH(TimerReload) ; 1
    ADDWF TMR1H,F ; 1
    MOVE?CT 1, T1CON, TMR1ON ; 1 start timer
    INT_RETURN
    ENDASM


    My code now compiles fine and i will have the chance to test it on the weekend. Apparrently i will have to buy a decent book on assembly after my next exam in october. Also I will clearly have to find a way to send beer to Darrell

    Default Yep!

    That's all it was, where do you learn those little tidbits short of having a great mentor, Ugh, OH GREAT ONE?

    Post the “vB code” code box

    Great work Darrel!

    Hi Michael,

    The forum will keep re-formatting your code. It removes spaces and changes things. To avoide this use the “vB code” code box.

    To use the “Code Brackets” see the “vB code” Hot button in the “Posting Rules” box at the bottom left of the screen while you are posting.

    It puts the code in the special box that protects the format better that the normal forum posting does...
    Hope that helps,
