M5Stack使用GUIslice库

作者:互联网



GUIslice是一个开源轻量级的图形库,用它来研究GUI框架很不错,还可以用buider拖曳式设计GUI,我很惊叹老外一个人就能开发出这么功能强大的框架
主页  
https://github.com/ImpulseAdventure/GUIslice     文档写的很好,用谷歌翻译基本就能看懂, 支持linux,arduino,m5stack  tft-espi   基本开源的嵌入式平台都支持
这里我实验用m5stack gray    有三个实体按键
在vscode里pio内新建一个工程  平台 esp32   开发板 m5stack-grey   架构arduino    引入两个库  M5Stack      GUIslice(因为网的原因引入github上得库有时很很慢,需要等)
如图

 

在库文件.pio\libdeps\m5stack-grey\GUIslice\src\GUIslice_config.h    中反注释这一行

  #include "../configs/esp-shld-m5stack.h"  这样就给GUIslice配置了设备驱动 如图

 

 

选择一个例子复制到main.cpp里,记得加入  #include <arduino.h>  这里选择   ex04_m5_ctrls

// GUIslice Library Examples
// - Calvin Hass
// - https://www.impulseadventure.com/elec/guislice-gui.html
// - https://github.com/ImpulseAdventure/GUIslice
// - Example 04 (M5stack): Dynamic content with integrated button control
//   - Same as Example 04 (Arduino), except adds GPIO pin input control
//     IMPORTANT: See notes under Button Control
//   - Demonstrates push buttons, checkboxes and slider controls
//   - 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_*).
//
//GUIslice 库示例
// - 卡尔文哈斯
// - https://www.impulseadventure.com/elec/guislice-gui.html
// - https://github.com/ImpulseAdventure/GUIslice
// - 示例 04 (M5stack): 带有集成按钮控制的动态内容
// - 与示例 04 (Arduino) 相同,除了添加 GPIO 引脚输入控制
// 重要:请参阅按钮控件下的注释
// - 演示按钮、复选框和滑块控件
// - 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_*)。
