    There're virtually thousands of reference designs available freely online.
    Choose your microcontroller and continue from there...

    Re: 7 x 21 dot matrix led display?

    In this case I'd use one of the following:

    1. Microchip PIC
    2. Atmel AVR
    3. Si-Labs 8051.

    According to Google.com there're 369,000 links...
    https://www.google.co.il/webhp?sourc...icrocontroller

    Try the first 1,000 - and post here the 50 that you chose as "finest".
