I'm trying to make an F/A-18C UFC like this:


Now a while ago I bought 6 x "4 digit 16 segment" z, which happen to be common anode (DataSheet)

What i am looking for is a way to drive all 4 using the minimum of wires - I guess I prefer I²C (IIC) but will work with what ever I can use

  • Note: I tried something with a HT16K33 IC, but apparently that will only work with Common Cathode

Thank you, and please let me know if you need more info, or suggestions to clarify my question

  • Do you mean LED (light emitting diode) rather than LCD (liquid crystal display)?

    LCDs do not have anodes or cathodes

    Added Datasheet, or at least the only document, that was available, from supplier - that took some digging ;) Oct 21 '20 at 20:47

It might be easier to just get a new common cathode led display or get the whole board from Adafruit https://learn.adafruit.com/14-segment-alpha-numeric-led-featherwing

  • I agree; however, I would like to avoid the extra money spending, and to use the junk (as my wife names it) that I have Oct 20 '20 at 14:16
  • Also this is the only place that had stock in the size ang 16-seg I needed at the time, i searched for months Oct 22 '20 at 21:31
