Grove RGB LCD Raspberry Pi Pico SDK example

An example / demo of scrolling asterisks on screen, outlining the correct way to set up the LCD using the Pico SDK port of Grove RGB LCD library.

CAUTION: THOUGH LCD SILKSCREEN MIGHT SUGGEST USING VCC, OR 5V INPUT FOR POWER THIS WILL BREAK YOUR PICO MICROCONTROLLER. POWER THE LCD VIA 3.3V OUTPUT FROM PICO PIN 36 INSTEAD, TO RUN THE SCREEN @ 3.3 VOLTS. THE SCREEN WILL STILL WORK JUST FINE AT LOWER VOLTAGE.
