What are the correct setting (pins) to put into the tft_espi files and display type. There are no correct examples for the 5 or 7 inch which have different controllers
I plan to use LovyanGFX with it, and based on my experience getting a couple of other Elecrow screens configured, and the Arduino_GFX config, I expect this to work:

@bbrook Hello there,
The driver library for 4.3-5.0-7.0-inch screens is not TFT_eSPI, but Arduino_GFX. Because these three screens are not SPI screens, but RGB screens.
Here are the links to the libraries for the three screens:
4.3-inch: https://drive.google.com/drive/folders/1EvlF0pDCMNra8kJZh4xRMjURbQ5PMZgo?usp=sharing
5.0-inch: https://drive.google.com/drive/folders/13Dc2WL0dZWq6ObegB3QwAzsPL9LZnCm-?usp=sharing
7.0-inch: https://drive.google.com/drive/folders/1ErqUf6u7qFaZTYgHWOLuTET5P0ZY3BIA?usp=sharing
I don't have the 5" screen yet, but I have one on the way. The display was recently added to the list of devices in the Arduino_GFX examples.
These are the settings used:

Working settings are here.
