    the algorithm of my project is

    1. 1st interrupt will turn the timer 0, timer 1 and analog to digital converter on and timers will start counting.
    2. an interrupt will turn of the timer 1 (timer 0 is still running) and send the no. of counts to hyperterminal.
    3.1st interrupt will come again and stop the timer 1 send its no of counts and analog to digital converter results to hyperterminal and turn on timer o timer 1 and analog to digital converter again on after clearing the previous values


    now please help me

    i have problems in interrupts in MPLAB the compiler is not responding to interrupts please give me atleast an example of interrupt program
