LED settings - Color order/swap illogical?

Issues
1

I was setting up the new GOVEE Outdoor Permanent Lights 2 (WS2814A Chip, physically confirmed) last night and really got confused with the Color Order/Swap behaviour.

So what works is Color Order BGR, Swap G&W

However, this makes no sense because
Selecting BGR with no swap has G and R working correctly, it is Blue swapped with White at that stage, but you need to swap G/W in WLED for it to work correctly.

This is surely incorrect?

The chip datasheet says the order is RGBW (sent in that order, high byte first)… so even if I presume some endian order on WLEDs behalf, I can’t figure out any context which explains the behaviour.

As an aside, maybe the color order/swap fields could be deprecated and instead just have a number of drop downs for ‘order’ instead, the number of drop downs and the options could be dynamically set according to the chip selected…

e.g. if you select SK6812/WS2814, you would get 4 drop downs (labelled 1,2,3,4) under a heading ‘order’ and each drop down will have R,G,B,W as an option, prefilled with 1 = R, 2 = G, 3 = B, 4 = W which matches the datasheet…
This means that through simple logic, you can set the colour to Red, if that physically appears blue, then you go to the Order 1 drop down and change it from Red to Blue… this would give a simple process for people to deal with non-default configurations with minimal logic required.

I have the same issue for my FW1906 strip. Each manufacturing of the Ledstrip can make its own mapping. So you should pic the colour order according to the Ledstrip not the led-IC.

The mind boggles as to what electronics engineer picks up a data sheet with OUT R, OUT G, OUT B, OUTW and deliberately mixes those up to the individual LED elements… :slight_smile:

It depends on the coding of the IC and the layout of the Ledstrip (optimal routing of the copper lines). The strips i have use an ic with R1,G1,B1,R2,G2,B2. So you can choose were you want to put RGB and the two white channels.
The final design is ugly from a logical point of view. Green, not used, warm white, white, Blue, Red.
So the easy way is to map the 5 options to the IC ports in WLED when you test your ledstrip.
