seven segmented led driver question

Hi everybody!

Does someone here ever tried to use a 7-segmented led driver? We are working with the MC14489 but we can’t figure out how to get it to work. I hope someone can show me some example code of data which needs to be send to it.


it’s probably worth searching the Arduino forums… i suspect you’ll need a piece of hardware like an Arduino between your PC and the driver anyway.


Thanks that’s indeed what we already did. Though no luck there :wink: Programmming the arduino isnt’ the problem that works perfectly. But interfacing those big 4" LEDs is. Maybe someone knows what drivers (microcontrollers) I could use?
