Driver for TFT display (ST7735) of ESP32 development board

[C WEIB]

In the EPS32 development board driver, I have seen in the building block library to drive the TFT display building block library, but it seems that the compiled firmware in the ESP32 does not start the role, I want to ask how to drive the TFT (ST7735) screen in the ESP32, I modified the firmware code to add support for the ESP32, can be displayed normally, but I do not know if my approach is correct, or there are other ways to drive I do not know yet. Attached is a code diagram and the effect

Good for you for getting that working!

We don't build the TFT driver into the generic ESP32 firmware since most ESP32 board do not have a TFT display. Also, there are a variety of TFT display types and they need different Adafruit libraries.

We do include TFT drivers for boards that have a built-in TFT display, such as the Citlab ED1 and the Adafruit Clue.

Those who want to use an external TFT display can do exactly what you did -- add a little code to include the appropriate Adafruit library, define the pin connections, and define the screen dimensions.
