Arduino touch screen library for XPT2046
This library has been tested on a 2.4" TFT screen that uses the ILI9341 display driver and XPT2046 touch controller.
These displays are available at low cost on eBay and AliExpress.
The library includes three sketches:
* TFT_Touch_Calibrate_v2: to calibrate and test the screen * TFT_Touch_Draw_2-4 : a simple paint program * TFT_Touch_Raw : a touch screen test sketch (Serial Monitor output only)
To make things really easy the calibration sketch reports the setup() calibration code to use in your sketch via a serial port message.
The library could be used with any graphics library but the examples use this one:
