## Setup
|
|
|
|
***
|
|
|
|
### Platformio.ini changes
|
|
|
|
In the `platformio.ini` file, uncomment the `TFT_eSPI` line within the [common] section, under `lib_deps`:
|
|
|
|
```ini
|
|
# 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:
|
|
|
|
```ini
|
|
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):
|
|
|
|
```ini
|
|
//#include <User_Setup.h> // Default setup is root library folder
|
|
```
|
|
|
|
* Add following line:
|
|
|
|
```ini
|
|
#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`
