This is a simple calculator using the CYD 2USB board ( ES32-2432S028 ) The User_setup for TFT_espi Library must be set up for your device and it uses the XPT-2046 Touchscreen library. It is not perfect but works reasonably well. Happy coding.

Her is a link to the correct display setup of TFT_User-seup required for the project https://github.com/witnessmenow/ESP32-Cheap-Yellow-Display/tree/main.

I would like to thank all of the community who have provided alot of input and Knowledge about this great little board and many other things. Special Thanks to https://github.com/witnessmenow/ESP32-Cheap-Yellow-Display
