A PWM LED constant-current driver with one-wire bus protocol. Would one only need 2 conductors, for combined power and digital control.

- klondike_ 4y agoThis already exists in commercially available form (WS2811 for example). But it might make an interesting learning exercise
- jononor 4y agoWS2811 and similar have a dedicated control signal line, and power+ground (3 leads total). I'd like to combine power and control, so that there is only two. Mostly because it allows to be compatible all the existing non-smart DC stuff.
