WebI am running fastLED on a ws2813 strip using arduino and esp32. It all works correctly, although my LEDs periodically flicker: they seem to return to black for a very brief moment and then relight in their colour. The flickering does not cause any weird action or colour to appear, so to me, it is not an issue of timing.

WebJan 19, 2024 · The problem is, in a nutshell, interrupts. Writing out WS2812 data requires some pretty tight timing. Tight enough that FastLED disables interrupts while it is writing out led data. This means that while the led data is being written out, any interrupts that happen will be delayed until all the led data is written out.

WebI'm using a Teensy 3.6 with a OctoWS2811 adapter and WS2815 LEDs. UPDATE: I've narrowed down the issue to the part of the code which uses bmpDraw to read a BMP image stored on the Teensy 3.6's SD card and uses that to draw onto the pixels. When using code to draw onto the leds (e.g. leds [x] = CRGB::Blue;) the glitching disappears. WebSep 13, 2024 · Having this problem with LED0 - Wemos D1 (8266) and FastLED.
