@Makuna I am having some issues getting any of the animation examples to run smoothly. Any animation appears to run at about 1 frame per second, very stuttered. It's an ESP8266 on a NodeMCU driving a WS8212b led strip (sending 5v data signal). Both FastLED and Ada Fruit seem to animate smoothly, but I cannot seem to debug what's going on with NeoPixelBus, I have tried both UART and DMA and get the same 1 to 2 fps result. Any ideas?
