Setup

Platformio.ini changes

In the platformio.ini file, uncomment the TFT_eSPI line within the [common] section, under lib_deps:

# platformio.ini
...
[common]
...
lib_deps =
    ...
  #For use of the TTGO T-Display ESP32 Module with integrated TFT display uncomment the following line  
    #TFT_eSPI
...

Also, while in the platformio.ini file, you must change the environment setup to build for just the esp32dev platform as follows:

Add lines to section:

default_envs = esp32dev
build_flags = ${common.build_flags_esp32}
  -D USERMOD_ST7789_DISPLAY

Save the platformio.ini file. Once this is saved, the required library files should be automatically downloaded for modifications in a later step.

TFT_eSPI Library Adjustments

We need to modify a file in the TFT_eSPI library. If you followed the directions to modify and save the platformio.ini file above, the User_Setup_Select.h file can be found in the /.pio/libdeps/esp32dev/TFT_eSPI folder.

Modify the User_Setup_Select.h file as follows:

• Comment out the following line (which is the 'default' setup file):

//#include <User_Setup.h>           // Default setup is root library folder

• Add following line:

#include <User_Setups/Setup_ST7789_Display.h>    // Setup file for ESP32 ST7789V SPI bus TFT

• Copy file "Setup_ST7789_Display.h" from usermod folder to /.pio/libdeps/esp32dev/TFT_eSPI/User_Setups
