Quick Start Guide for Arduino IDE
Follow these steps to get started with programming your LILYGO ESP32 T-Display Module using the Arduino IDE:
- Copy the TFT_eSPI library to your Arduino libraries directory (e.g., C:\Users\Your User Name\Documents\Arduino\libraries).
- Open Arduino IDE and navigate to the TFT_eSPI examples. For instance, the T-Display factory test program is located at TFT_eSPI -> FactoryTest.
- You can also use other sample programs provided by TFT_eSPI.
- In the Arduino IDE tool options, select the development board ESP32 Dev Module.
- Select Disable in the PSRAM option.
- Select 4MB in the Flash Size option. Keep other settings as default.
- Select the corresponding serial port. If unsure, remove all other serial ports, leaving only the board in the USB connection state, then select that one.
- Finally, click Upload (the right arrow next to the tick icon) to flash your code.
