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

You could try to decorate the fucntions update_buf() and fill_buff() as @micropython.native or @micropython.viper.

Thanks, I'll try that and report here.
