    Default Max7221

    Hi,
    I'm using MAX7221 display driver, I know how to set it up.
    I need to send serially a 16 bit number to the display, but I found that I need to decode the number into digits digit 1, digit 2... etc.
    Can you provide some guidance on how to do that please?
    my number is stored as 16 bit Word, how can I convert that into digits please?
    Max. number is 9999, so I'm using only 4 digits 7 segment display.
    Regards,
    Suded

    Look up the DIG operator in the manual.
