2 digit 7 segment display

  • smaw     18th May 2020 Member 0 Permalink

    I'm trying to make a calculator for the first time (not using wifi though). I have it all working and it outputs a binary number. How can I turn this into a 2 digit 7 segment display? Thanks :)

    EDIT: First, you'd need to convert the binary to decimal, using something like
    2286408View Save 2286408


    Then, you could use these:
    232172View Save 232172


    You can program them to accept a signal corresponding to a decimal number, and return the appropriate pulses for a 7-seg display. For this use case, you would have 64 input rows on the chip (assuming your calculator is 6-bit), and 2*7=14 output columns.

    If you need help implementing these components into your calculator, PM me
