mote does not support brightness #19

Closed dglaude closed 6 years ago

dglaude commented 7 years ago

I just noticed that while the APA102 on the mote stick support brightness but the mote library does not expose this. Maybe because the serial protocol does not?

Is there a plan to add this? Else what is the limitation?

The Mote firmware doesn't expose this feature at all, since the 5bit brightness setting on the APA102s is at best useless and at worst actively thwarts things like channel-dependent gamma correction. I'm planning to remove support for it in Mote pHAT in favour of simply scaling the colour values as part of the suite of changes in: https://github.com/pimoroni/mote/issues/18
