ESP32-S3 and touch driver wiring

V2.0 Schematic Diagram:

Pin definition in the touch.h:

 #define TOUCH_GT911_SCL 20//20
 #define TOUCH_GT911_SDA 19//19

Tips:

Please refer to this post to check how to connect sensor using I2C pin and also use touch with it.

V3.0 Schematic Diagram:

Version 3.0 adds touch timing control based on Version 2.0 to prevent touch failures. When writing programs, you need to build upon the Version 2.0 program to implement the timing control logic.
