Grove Chainable RGB LED v2.0: How to Get White?

How to get the white colours on a Grove Chainable RGB LED v2.0?

Sending myRGB.setColorRGB(0, 255, 255, 255); shows a redish colour, not the expected white.

Thank you!

myRGB.setColorRGB(0, 255, 255, 255) What color is it? Do you have any pictures?

leds.setColorRGB(0, 255, 255, 255) gives red.

@reivilo Is your hardware connection working? 14 and 12 pin correspond to CLK_PIN and DATA_PIN

Yes, I can display primary colours like red, green and blue.

That should be able to get white by adjusting R, G, and B.

Indeed, but why the recommended code leds.setColorRGB(0, 255, 255, 255) doesn’t show white as expected?

Is the RGB LED faulty?

@Baozhu Is my RGB LED defective?

I am not sure, I read the specification carefully, the specification does not specify that (255,255,255) shows white.

Not very convincing I’m afraid.

I performed more tests with the same RGB LED but attached to the Wio Terminal and the Seeeduino v4. No problem to get white colour with 255,255,255 with either 3.3V or 5V.

So the problem may come from the Wio Link board.
