    Question Why the first PIC

    Hi Shaig,

    I don't understand why you want to use interrupts on the first PIC and then let the second one detect it. Please elaborate it.
    Regards

    Question

    Also, why don't you use one F877 instead of two F84s?

    What is the idea behind having two PICs? Are they far away from each other?
