SetLedColor array overload doesn't update LEDs 0-3 correctly

[jmfranz]

Subject of the issue

Calling setLEDColors(rArray,gArray,bArray,length) fails to update the colors on LEDs 0,1,2, and 3. Other LEDs are OK.

Calling setLEDColors(color,index) for each led also fails. Interestingly turning on the individual LEDs on the setup() method works.

Your workbench

• ESP32-S2 WROM
• QwiiC LED Stick (Red version)
• USB-C Power to ESP32, i2c cables (not using qwiic connector)
• USB-C

Steps to reproduce

Call the following method from the loop when a button is pressed:

Expected behaviour

LEDs 0 and 1 should be violet colour, 2 and 3 blue when value is less than 2.5

Upper LEDs work as expected when values are greater than 0

Actual behaviour

LEDs 0-3 fail to be lit with the correct colour or to turn on at all. Pictures: https://imgur.com/a/vAocXx8

Color Gradient example also fails on LEDs 0-3: https://imgur.com/a/2ocgn0J

@jmfranz thanks for the example code and the details of your issue! I will be taking a look into this in the next week or so, once my workload frees up a little.

@makin-stuff Thanks! FIY I have two LED boards and both behave the same.

It feels like the green value for LEDs 0 and 1 are being ignored.

Hi everyone! Thanks for the feedback. I'm working on some projects currently, but will be able to check back on this next week probably.
