Make color definitions more global in source code

I can imagine that these colors will be part of some "theme" defined in RAM or LittleFS filesystem config file which could be easily changed on watch or over BLE....

Idea: Faster LCD redraw with 16 MHz I2S (instead of 8 MHz SPI)

Thanks @TT-392 for testing. I have also 10x probes, but probably the device to which NRF52 is soldered has some traces that weren't designed for 16 MHz. So this might...

Idea: Faster LCD redraw with 16 MHz I2S (instead of 8 MHz SPI)

@TT-392 What about changing the I2S clock divider on the fly? You could start with speed like 4-8 MHz for the first few bytes, then by PPI / timer enable...

Idea: Faster LCD redraw with 16 MHz I2S (instead of 8 MHz SPI)

@TT-392 wow, now I understand those 7 bit banged bits and CMD signal switched by PPI. That's really clever how you solved that non dividable 65 bits by 8 in...

Problem if we do not use PA0 as port

Thanks, if you create a pull-request, I will merge it.
