    Greetings all,

    I'm in the middle of a project at the minute and i'm stumped. Basically i'm using one of the internal comparators of the PIC16F88 to monitor a sensor input on pin RA1, when this input drops below the reference voltage, I want to induce an output on pin RB4. This part of my project works correctly.

    However I also want to set pin RB4 high if another input pin RA4 is high. I have wrote the following 'C' code in Source Boost;
    If the result of the comparison is high I am receiving an output on Pin RB4, but if the result of the comparison is low and I set Pin RA4 high, there is no output on pin RB4 when I plug the PIC into my circuit which is what I require.

    Can anyone see anything wrong with the above code?
