WS2812b support #2

Open dani-carbonell opened 2 weeks ago

Great project, thanks for sharing :) I am looking to build som props using these leds.

Is there any plans to add Neopixels support? I have seen that some manufactures use the SK6812 (PWM 1.2KHz) and WS6812b (PWM 0.4KHz)indistinctly and the range of form factor still makes it interesting for small POV props.

For the sake of curiosity I measured the PWM of those LEDs: The setup consists on a red LED pointing at the strip and an oscilloscope

I am getting consistent readings of 4.54KHz Apparently manufacturers keep increasing this frequency and it varies among diferent size of pixels

So I think that for small segments the 800Kbps would perform just OK as long as the PWM is good enought
