Firmware
Seems to work pretty good with Tasmota-Display.

- 2.8″ TOUCH LCD SPI FOR ESP8266 (NODEMCU)
- Code seems to work...
- Interfacing ESP8266 NodeMCU with ILI9341 TFT 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.
- Once you add
- Code seems to work...
