IoT-Bus Touch Draw Example
This example demonstrates the use of both the IoT-Bus Display and the touchscreen. In this example we are using a
forked version of Bodmer’s
TFT_eSPI library with User_Setup already setup for IoT-Bus Display which you can find
here. We are also using a forked version of Paul Stoffgren’s XPT2046_Touchscreen library which has been enhanced
to perform mapping of raw touch Data to screen coordinates. It has also been modified to disable the PENIRQ line so
that we use one less pin. You will find other examples in the examples repository that use Adafruit libraries that work
in a very similar way.
// include touchscreen library
#include <XPT2046_Touchscreen.h>
// Call up the TFT driver library
#include <TFT_eSPI.h> // Hardware-specific library
#include <SPI.h>
// Invoke custom TFT driver library
TFT_eSPI tft = TFT_eSPI(); // Invoke custom library
// These pins are defined in User_Setup.h and have already been setup to be correct

//#define TFT_MOSI 23
//#define TFT_SCLK 18
//#define TFT_CS 5 // Chip select control pin
//#define TFT_DC 27 // Data Command control pin
//#define TFT_RST -1 // Set TFT_RST to -1 if display RESET is connected to ESP32

In the initial section of the example we include the libraries required, declare both the display and touch screen for
