GD32H759拥有强大的显示功能，能轻松的驱动RGB屏，当然离不开LVGL这个强大的图形工具！由于此开发板刚推出来，查不到任何相关的LVGL的移植先例，花费了好几天，终于成功，特此分享如下：
【移植步骤】
1、下载官方源码：Gitee 极速下载/littlevGL
2、新建littlevlg文件夹，把src目录下的相关文件复制进来，复制后目录如下：
由于源码需要添加的目录太多，我这里根据网友的经验，把相关文件整一下，各位也可以根据其他的移植方法添加相关的文件与目录。
3、把以上文件下examples的目录，的所有文件均添加进工种分组中。
4、新建工程分组lvgl/porting，新建littlevgl_support.c以及.h文件。
5、在littlevgl_support.c，分别驱动屏幕驱动以及sram驱动。详细代码如下：
#include "gd32h7xx.h"
#include "systick.h"
#include <stdio.h>
#include "main.h"
#include "gd32h759i_eval.h"
