Neopixel.timings method bug

Open rdagger opened this issue 7 years ago • 2 comments

The Neopixel.timings() method argument order is wrong but more seriously it generates pulses that are out of order. The faulty pattern looks like: T1L always precedes T0H instead of T1L following T1H. and T0L always precedes T1H instead of T0L following T0H. Basically the lows are out of order. incorrect low spacing

Thanks, I'll review the Neopixel timings next week.

Neopixel and apa102 recommend using SPI module driver, setting the bps to 8 megabits and transferring 1 bit（ws2812） per byte（SPI）, which is very stable. In addition, the timing of WS2812 is very insensitive to low-level stretching, just do not exceed reset time.
