I didn't remove the example. It is still on
https://github.com/DeqingSun/ch55xduino/blob/ch55xduino/ch55xduino/ch55x/libraries/WS2812/examples/chaseTest/chaseTest.ino
I've tested on my WS2812 and it worked well. If doesn't work on your side. Would you mind providing more sample of the wrong color?

Hi,
Yes, I can see your WS2812 code now. I don't know why the ZIP I downloaded didn't have this demo code.
I will study it tonight.
Thanks,

Hi,
I have fixed this issue. It's caused by the time requirement is different from the one in library.
WS2812D-F8 | WS2812B-Mini
T0H | 400±150ns | 300±80ns
T0L | 850±150ns | 790±210ns
T1H | 850±150ns | 790±210ns
T1L | 400±150ns | 790±210ns
RES | >50us | >280us
After I change the data transfter time as the one of WS2812B-Mini, it works well.
Thanks a lot for your works.

How did you change the timing? It seems the only possibility here is changing the number of nops in the code.
I have some issues with the last of 16 LEDs. The last LED always has blue unchanged (stays off if it's off, on if it is on).

@buttim if you see a lot of nop, you should update the CH55xduino
Now you can change WS2812_DELAY

That's really good news. How comes I can't see the possibility to upgrade from the IDE?

Did not add the URL in settings actually

Version 0.20 has no problem at all, did not even have to change the timings. Thanks a lot
