LVGL Micropython on the Waveshare ESP32-C6-LCD-1.47

This is some notes/scripts/etc that I've put together with the hopes of saving someone else a bunch of time if they ever want to get this thing running. I'm sure there's a better way to do this with custom board files and stuff but for the time being, this will at least serve as a starting point.

With the esp32c6 only somewhat recently getting official micropython support and the forked lv_micropython seemingly not rebasing anytime soon, kdschlosser has created a spinoff project to get things working with mainline micropython. It works great for this!

• Waveshare Wiki for ESP32-C6-LCD-1.74 - a useful reference. I was able to utilize the demos and documentation to determine which pins to fiddle with to get the screen working

compiled Sonoff-Tasmota from https://github.com/arendst/Sonoff-Tasmota.git (read directions there) and save the .bin somewhere easy to get to

rip the chip off your arduino, you're going to use that bish as an ftdi adapter

wire it up like this:

arduino     sonoff pins
3.3v        pin 1
RX          pin 2
TX          pin 3
