    Although you say that you've read them, the results don't match what the threads recommend.

    ok, added following to the start...

    Code:
    @ device pic16F877A, HS_OSC
@ device WDT_OFF
@ device PWRT_OFF
@ device BOD_OFF
@ device LVP_OFF
@ device WRT_OFF
@ device CPD_OFF
@ device DEBUG_OFF
    and I get the following error during compile...

    Code:
    D:\Bedini\PIC code\bedini 1>pbpw -p16f877 test1.bas -v

    my INC dir only has an M16F87XA.inc file does that make a diference?

    Command line options override anything in your program.

    You've compiled it for a 16F877
    Code:
    pbpw -p16f877 test1.bas
    And put @ device pic16F877A, ... in the program.

    What other problems are you having?

    The "A" version has a few things different. Do a data sheet compare and you will find them.

    i dont believe that pdf is entirely acurite...

    problems i was havin were pwm lockups, ie pwm suddenly stopping during normal running...
    pwm not starting up...
    wild fluctuations on ADC's (i using internal Vref)
    and 'clunky' operation... as in what appears to be little 'freezes' during operation

    but now... works perfectly every time... ADC's seem far more stable...
