WS2812b and similar LEDs - do we need all time running tight loop for control?

[CuriousOne]

Thanks, I only will have two of such leds, and both should display same color. So what if I connect their inputs in parallel?

[Dave]

Yes, That can be done as I have paralleled up to 8 strings of 30 pixels each.

The WS2812 need fast pulses and your PIC should be fast as well.

The APA101 are much more tolerant and can be driven slower enough for any PIC to handle.
