硬件:野火挑战者STM32F429 V1开发版,5寸屏
软件:最新版本的STM32CubeF4固件库,TouchGFXDesigner v4.13和 STM32CubeMX v5.6.1,开发环境MDK v5.29
1.准备一套STM32F429开发版,和下载工具
2.下载 TouchGFXDesigner v4.13
压缩包下载完后,解压如下:
Projects目录下有STM32H7B3I-DK的工程,可以用来参考。touchGFX Designer的PC端安装包在Utilities目录下,找到后并安装。
3.下载 STM32CubeMX v5.6.1
安装完STM32CubeMX v5.6.1版本后,还需要安装X_CUBE_TOUCHGFX软件包,安装路径如下:
4.下载 MDK v5.27以上版本
效果演示:
代码持续更新中:
github代码下载地址 https://gitee.com/Aladdin-Wang/hellotouchGFX.git
觉得有用的话,欢迎给个小星星
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,设备、组件和软件包的使用方法,下载并安装Env开发工工具
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STM32F29 V1开发板,所以可以选择stm32f29-fire-challenger的BSP,在此BSP的基础上移植touchgfx,首先找到如下目录:…\rt-thread\bsp\stm32\stm32f429-fire-challenger。
搭建项目框架
打开 Env 工具进入 stm32f429-fire-challenger 目录,运行scons --dist 命令。使用此命令会在 stm32f429-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stm32f429-fire-challenger 的 BSP,可以随意拷贝此 BSP 到任何目录下使用。
进入dist目录下,把工程里面的 stm32f429-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BSP,可以参考官方教程
打开…\board\CubeMX_Config\CubeMX_Config.ioc,由于bsp已经配置了很多外设,所以只需要修改部分配置就可以了
打开CRC
重新配置LTCD
打开freertos
打开Touchgfx
配置Touchgfx
配置SPI_FLASH管脚
生成工程
通过TouchGFX 4.13.0 Designer打开ApplicationTemplate.touchgfx.part
配置TouchGFX UI,创建三个页面
拷贝OSWrappers.cpp,重命名为OSWrappers_RTT.cpp文件
更改代码

配置fal_cfg.h,
tgfx分区用于touchgfx的资源存储,其他分区用于OTA、文件系统和系统参数配置。

制作STM32F429的SPI FLASH下载算法(看附文)
修改工程模版template.uvprojx
编辑链接文件
将位图数据从外部flash复制到缓存
此时重新生成 MDK工程,便可以下载到板子上运行。

配置模拟I2C
在applications文件夹下新建gtxx_ccollect.c文件,添加一下内容
