This PR creates a new demo firmware target,
leds_and_lcd
, intended to do what the name implies - show the LEDs (GPIO & RGB LEDs) being used, and draw some stuff to the LCD.This updates the existing LCD test code to now print a "Running on Sonata" and "Protected by CHERI" message, with a little cherry bitmap.
It also adds an additional compartment
rgbled_lerp
which just linearly interpolates between colours on the RGB LEDs to slowly cycle through different colours.
