Where to define display

[alidaf]

I'm trying to get started with an ESP32-WROVER (ESP32-DEVKITC) and a Waveshare ST7789V display (2", 240x320). When loading an example it says it is for the ILI9341 display, so where do I define the display and the GPIO connections?

NVM, I figured out that when trying to edit the header file, the Arduino IDE doesn't save it. I had to edit the header file in another editor.
