RP2040PicoW

RP2040 Pico W, SunFounder Kepler kit, Waveshare and Pimoroni code for sharing.

Well met,

Initial day with the Kepler kit, continuing the Day's of yorecode.

LCD, Charger, Wifi web

First up is a little text scrolling routine for insertion in Paul McWhorter's lcd1602.py, which is configured for Pin 6,7 an I²C 1.

New to github, this is not a fork, pull request yet, just a code fragment for inclusion in the LCD class of lcd1602.py, add to the bottom of the LCD class. First day, will polish, maybe.

Paul McWhorter's Pico W Kepler kit introduction, lessons, with hardware and software tutorials. Lessons 22, 24, 28 in particular, for hints on LCD1602, charger module, wifi web apis

Add to lcd1602.py, as methods in lcd1602.py from lesson 22
