Andúril light with true rgb? (lemmy.zip)

Is there an andúril light with actual rgb aux lights instead of the resistor ones or the single colour ones? If no, is it even possible with the microchip they use? I know its a pretty limited chip.

They need one pin for all neopixels. You can daisy chain them. You have to start sending the colours in order from last to first neopixel. Only problem is that it needs to be precise but idk how precise.

1ms shouldn't be too hard (would just have to have the code to handle it be in the main loop, ideally, rather than an event handler). If it's significantly under 1ms might be a problem.
