    Default messuring 12V

    can some one help me with the code for messuring 12V power .
    So i can put a porta.4 high?
    porta.4 must high when the power is below 10Volts.
    I use a 16F628 or later a 16F72

    Cool

    Hi,

    It's not the McDo Drive-in of code here ...

    how do you want to use your processor ??? Hysteresis needed ???

    as many ways are possible I can't ( and do not want ) give you a ready to burn application.

    - use of comparators ?
    - use of RCTime command ?
    - use of the CCP module ?
    - ???

    Now ... as Porta.4 is generally an open collector pin ... you can't make it high !!! ( lol ) but just let it float ...

    try to have a clearer view of what you want to do ... and show us what you already have looked for.

    certainly the answer is " RTFM " or " RTFDataSheet " !!!
