LED signalling mirror

I need to use an external RGB led for signalling.

Does the RGB.mirrorTo function applied using STARTUP continue to enable external RGB leds if subsequent calls are made using LED Signalling?

As the description says. Everything the onboard RGB LED does the morrored LEDs will do too.
If you also set the bootloader flag this will even be a sticky setting which will not require future RGB.mirrorTo() calls to enable the feature.

Thanks. I have previously used the RGB mirrorTo function with direct control of the leds using the RGB function. The issue I was addressing is ‘if I set up RGB.mirrorTo at startup does this continue to apply if I subsequently use the LED signalling functions instead of the Direct RGB functions?’

I assume it does but will cut a small test routine to confirm when I have my test bed handy.
