(Why in hell do dev-board makers, & Arduino for that matter, think changing the actual GPIO numbers to some random shit was a good idea???)
Firmware
Seems to work pretty good with Tasmota-Display.

- Code seems to work...
- Once you add
#include <Arduino.h>
and#include <SPI.h>
- Aside from tripping over the WDT... :(
- tft.fillRect() seems to kick the watchdog.
- testFilledCircles() kicks the watchdog instead of returning.
- SOLUTION: Add
ESP.wdtFeed();
immediately before most calls to the shitty Adafruit library functions.

- Code seems to work...
