1.使用RT-Thread 系统实现DIY数字仪表（一）——STM32CUBMX5.6移植touchGFX4.13
2.使用RT-Thread 系统实现DIY数字仪表（二）——把TouchGFX移植到RTThread系统
3.使用RT-Thread 系统实现DIY数字仪表（三）——RTThread系统实现物联网平台
4.使用RT-Thread 系统实现DIY数字仪表（四）——完善TouchGFX仪表界面
5.使用RT-Thread 系统实现DIY数字仪表（五）——开发微信小程序

实验平台：

硬件： 野火挑战者STM32F767 V1开发版
软件： TouchGFXDesigner v4.13和 STM32CubeMX v5.6.0，MDK v5.29，RT-Thread env 工具

实验前准备工作：

1.准备一套野火挑战者STM32F767 开发版或其他核心板
2.安装 TouchGFXDesigner v4.13
3.安装STM32CubeMX v5.6.0和X_CUBE_TOUCHGFX软件包
4.安装 MDK v5.27以上版本
5.下载 RTThread源码包https://gitee.com/rtthread/rt-thread

下载：

代码持续更新中：github代码下载地址https://gitee.com/Aladdin-Wang/hellotouchGFX.git

加微信备注touchgfx，拉入touchgfx-rtthread技术交流群共同学习
在这里插入图片描述

移植RT-Thread的BSP模板： 1.学习RT-Thread系统（学过的可以跳过此步骤） 通读RT-Thread系统官方学习文档，https://www.rt-thread.org/document/site/ 快速了解RT-Thread系统的内核，下载安装Env开发工工具了解设备和驱动的使用方法： 2.移植BSP 参考官方使用 Env 创建 RT-Thread 项目工程的教程选择 BSP
获取 RT-Thread 源代码后需要根据自己手上的开发板型号找到对应的 BSP，我实验所使用的是野火的STM32F767 V1开发板，所以可以选择别人已经做好的stm32f767-fire-challenger的DSP，在此DSP的基础上移植touchgfx，首先找到如下目录：…\rt-thread-v4.0.2\rt-thread\bsp\stm32\stm32f767-fire-challenger。搭建项目框架
打开 Env 工具进入 stm32f767-fire-challenger 目录，运行scons --dist 命令。使用此命令会在 stm32f767-fire-challenger 目录下生成 dist 目录，这便是开发项目的目录结构，RT-Thread 源码位于项目文件夹内，仅包含stm32f767-fire-challenger 的 BSP，可以随意拷贝此 BSP 到任何目录下使用。
在这里插入图片描述

进入dist目录下，把工程里面的 stm32f767-fire-challenger压缩包拷贝到你的项目目录下待使用。制作BSP
也可以自己重新制作对应自己板子的DSP，可以参考官方教程 3.替换工程里CubeMX_Config文件夹

把RT-Thread 系统实现DIY数字仪表（一）工程的以下文件拷贝到BSP模版CubeMX_Config文件夹中，替换掉原先的文件，打开demo1重新生成工程。
在这里插入图片描述

4.更改操作系统的接口文件

拷贝OSWrappers.cpp，重命名为OSWrappers_RTT.cpp文件

更改代码
