针对M5s的按键修改的例程

// GUIslice Library Examples
// - Calvin Hass
// - https://www.impulseadventure.com/elec/guislice-gui.html
// - https://github.com/ImpulseAdventure/GUIslice
// - Example 05 (Arduino):
// - Multiple page handling, checkboxes
// - NOTE: This is the simple version of the example without
// optimizing for memory consumption. Therefore, it may not
// run on Arduino devices with limited memory. A "minimal"
// version is located in the "arduino_min" folder which includes
// FLASH memory optimization for reduced memory devices.
//
// ARDUINO NOTES:
// - GUIslice_config.h must be edited to match the pinout connections
// between the Arduino CPU and the display controller (see ADAGFX_PIN_*).
// - To support a larger number of GUI elements, it is recommended to
// use a CPU that provides more than 2KB of SRAM (eg. ATmega2560).
//
//
// GUIslice 库示例
// - 卡尔文哈斯
// - https://www.impulseadventure.com/elec/guislice-gui.html
// - https://github.com/ImpulseAdventure/GUIslice
// - 示例 05（Arduino）：
// - 多页处理，复选框
// - 注意：这是示例的简单版本，没有
// 优化内存消耗。 因此，它可能不会
// 在内存有限的 Arduino 设备上运行。 一个“最小”
// 版本位于“arduino_min”文件夹中，其中包括
// 闪存优化减少内存设备。
//
// ARDUINO 注释：
// - 必须编辑 GUIslice_config.h 以匹配引脚连接
// 在 Arduino CPU 和显示控制器之间（参见 ADAGFX_PIN_*）。
// - 为了支持更多的 GUI 元素，建议使用
// 使用提供超过 2KB SRAM 的 CPU（例如 ATmega2560）。
