注意，本章节的代码适配的是GDEW0154T8驱动源码，已经停产，所以只能参考实现思路，此工程在新屏幕中是跑不起来的。
如果需要最新版本的屏幕驱动代码，参考分支dev_17_all_d67中的
dev17_all_d67/main/src/driver/ds_screen.c 为GDEW0154D67驱动源码（目前使用）

注意：由于厂家前后期提供的墨水屏驱动芯片不一样，所以不同的墨水屏驱动代码需要根据自己购买的屏幕型号进行替换，驱动代码见分支：

有了图标、有了文字数据，如何放到同一个页面里面呢？
- 1、初始化一个152*152像素的数组
- 2、根据UI要求，设置图标和文字的初始位置
- 3、根据图标和文字数组内容，把像素数组的对于像素设置为亮灭
