(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???)

  • Code seems to work...

  • 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.
