It has been tested sucessfully with following setup:

• Windows 10 x64
• Arduino IDE 1.8.18
• ESP32 D1 mini (other uC boards work as well with some modifications depending on the model)
• OLED TFT ILI9341 display 2.8" 320x240px (red colored board version)

Requires following extensions installed to the Arduino IDE:

• Bodmer's "TFT_eSPI" library (I used v2.3.70)
• Powerbroker2's "ELMDuino" (I used 2.6.4)
