【目标】
瑞萨RA8D1 LVGL移植，基于mdk的环境搭建。
【开发环境】
win11
【硬件】
1、CPKCOR-RA8D1B核心板
2、拓展板（CPKEXP-EKRA8X1）
【开发工具】
1、keil+fsp
2、vscode+fsp
【移植LVGL】
1、首先准备一个基于ra8d1的led工程。
2、rasc提供了lvgl的组件，打开rasc后，在stack中添加lvgl
3、打开bsp，开启sdram,将堆栈空间加大：
4、开启LCD时钟，时钟为240MHz
【配置LVGL】
1、关闭RTOS
2、修改自定义参数：
3、新建MIPI Display
然后修改LIN为1
生成工程，使用mdk打开工程。
【自定义代码添加】

#endif编译后下载到开发板。可以看到成功的运行了demo
【添加自定义工程】
使用guiguider设计一个基于lvgl9的窗口：
生成工程后，拷贝generated到工程中，并添加工程文件/目录
【实验效果】
【总结】
对于其他的MCU系列来说，RA的生态现在非常好了，通过图形化的配置，可以快速的创建工程，并验证开发板的功能。
