Multicolour LED buttons


Deadline

Recommended Posts

Hi all - so, I'm just conceptualising my MIDIbox and am getting a bit excited. I came across a button with red and green built in LEDs, and thought they would be good for telling me when a clip is loaded (yellow), playing (green) and red (recording) in Ableton. But - does this mean that each button will take up two LEDs in the core? This could be problematic, seeing as so far I've got 81 of these buttons in my design... any ideas how to get around this one please?

Thanks!

James

there is a BLM application and some hack of it through the forum, especially in user project section

no need to use 1 DOUT for 1 LED : MATRIX is the answer !

Yes, indeed. Sorry, didn't think about multiplexing. :rolleyes:
