See the following Instruction:]. I have an ILI9341 and was looking at programming some touch functions on it. See Photos. You'll learn how to setup the pin in your program, and read the touch status. There are forks from the original ESP32 repo including the new files, but nothing official yet. I needed guidance on choosing the right touch display + ESP combo and I'm using the ESP since BLE and WiFi are already built-in. Reinstalled the IDE. So when you download the new version, make sure that you only use the files that come with the current download, and not files from other versions. MicroPython 101 . The function will be called if a touch sensor value falls below the given threshold for ESP32 or rises above the given threshold for ESP32-S2/S3. MDO. The final result resembles the connection shown below. 3rd Party Boards. This The ESP32-S3-Touch-LCD-7 is a low-cost, high-performance microcontroller development board designed by Waveshare.
