ART-PI（RTThread）+TouchGFX+正点原子7寸屏开发
ART-PI（RTThread）+TouchGFX+正点原子7寸屏开发硬件及软件组成新建ART-PI模板工程配置TouchGFX配置显示驱动配置触摸驱动硬件及软件组成睿德赛ART-PI开发板正点原子ATK-MD0700R-1024600-IPS液晶显示屏（7寸）RTThread Studio软件TouchGFXDesigner-4.15.0软件（可不下载）新建ART-PI模板工程在RT-Thread_Source_Code中安装源码包在Chip_Support_Packages中安装芯片包在Board_Support_Package中安装ART-PI开发板的板级支持包文件-新建-RT-Thread项目-基于开发板（工程名自行定义）点击项目-构建项目，下载程序到ART-PI开发板，此时应有板载LED灯闪烁配置TouchGFX打开RT-Thread Settings加载TouchGFX库使能C++特性支持（因touchGFX基于C++编写）项目-属性（配置支持C++的编译，否则编译程序会报错）配置显示驱动使能SDRAM和LCD函数功能打开DMA2D传输和CRC校验宏定义（STM32H7图形加速）根据所用屏幕的参数信息修改LCD配置文件（IPS和TN屏时序是我个人查网上得到的）右键-打开方式-文本编辑器，修改TouchGFX的应用模板信息为24位色深，分辨率1024*600（即对应所用屏幕）至此下载程序，屏幕应能显示例程，但触摸无效配置触摸驱动使能软件模拟I2C（屏幕触摸芯片使用I2C通信）使能I2C总线及引脚修改STM32的触摸控制器驱动（含FT5426、GT9147、GT911）将以下代码覆盖STM32TouchController.cpp的文件内容/** ****************************************************************************** * File Name : STM32TouchController.cpp ****************************************************************************** * @attention * * h2centercopy; Copyright (c) 2020 STMicroelectronics. * All rights reserved./center/h2 * * This software component is licensed by ST under Ultimate Liberty license * SLA0044, the "License"; You may not use this file except in compliance with * the License.
