Fast method for writing to a Neopixel strip
Posted: Wed May 16, 2018 1:14 pm
Hello,
I'm currently driving a strip of 72 Neopixel LEDs (WS2812) from a pyboard using JanBednarik's ws2812 library [1]. I would like to know if there are other options which would provide faster refresh rates?
I've looked at aykevl's FastLED [2], but I believe that it accelerates the computation of animations but relies on "esp.neopixel_write()" to drive the LEDs.
Thanks,
- Mathieu
