    my vref=4v, vin=3.6 and my vout=9v.can someone help me which part of the coding need to be edit.please...
    Vref = 4v - what is Vref connected to?
    Vin = 3.6v - what is Vin connected to?
    Vout = 9v - what is Vout connected to?

    Read the datasheet for the 16F877A!
    Can MCLR be turned off?
    How many oscillator modes does the 16F877A have? What are they?
