XPT2046 触摸校正

rduino IDE下载：XPT2046_TouchScreen库。

#define TOUCH_CS_PIN 33

#define TOUCH_IRQ_PIN 34

触摸参数需要调校：
打开示例：GUIslice->arduino->diag_ard_touch_calib
运行后，点击屏幕四角的点，最后会出现参数

ADATOUCH_X_MIN
ADATOUCH_X_MAX
ADATOUCH_Y_MIN
ADATOUCH_Y_MAX
把这些数值修改到esp-tftespi-default-xpt2046.h中。

#ifndef _GUISLICE_CONFIG_ARD_H_
#define _GUISLICE_CONFIG_ARD_H_// =============================================================================
// GUIslice library (example user configuration) for:
//   - CPU:     ESP8266 / ESP32
//   - Display: TFT_eSPI (defined by TFT_eSPI config)
//   - Touch:   XPT2046 (Resistive)
//   - Wiring:  Custom breakout
//              - Pinout defined by TFT_eSPI's User_Setup.h
//
//   - Example display:
//     -
//
// TFT_eSPI Notes:
//   - When using the TFT_eSPI library, there are additional
//     library-specific configuration files that may need
//     customization (including pin configuration), such as
//     "User_Setup_Select.h" (typically located in the
//     Arduino /libraries/TFT_eSPI folder). Please refer to
//     Bodmer's TFT_eSPI library for more details:
//     https://github.com/Bodmer/TFT_eSPI
//
//   - To avoid potential SPI conflicts, it is recommended
//     that SUPPORT_TRANSACTIONS is defined in TFT_eSPI's "User Setup"
//
//   - For touch support by external drivers, the TFT_eSPI's integrated
//     XPT2046 touch driver should be disabled. This can be done by
//     ensuring that TFT_eSPI's User_Setup.h does not define TOUCH_CS
//     (ie. it should be commented out).
//
// DIRECTIONS:
// - To use this example configuration, include in "GUIslice_config.h"
//
// WIRING:
// - As this config file is designed for a breakout board, customization
//   of the Pinout in SECTION 2 will be required to match your display.
