WS2812 Sim OK but fails to built

[RGV250]

Hi,
I have just tried a simple demo for WS2812, it simulates OK but when i try to compile and download to the device I get an error
WS2812_Demo1.c:(.text+0x44c4): undefined reference to `nop' several times over.

Also not sure if I have WS2812 or WS2812B but I get the same error.

Hi Bob,

Thanks for letting us know. It looks like your the first to try this component on an rpi. Should work fine on an arduino or an esp32. I'll look into it for you and see if we can get it working.

Hi Ben, Any chance you might get a fix before you break up for Xmas.
