一款实用的echarts基于html5 canvas中国地图省市地区介绍代码，鼠标悬浮地图省份区域时，悬浮提示方式显示自定义该区域文字内容介绍效果。(A practical echarts based on the HTML5 canvas map of China and cities and regions to introduce the code. When the mouse suspends the province area, the suspension prompts display the effect of the definition of the text content of the region.)

大致思路说说，就是在外部SRAM里面做了一个大数组[320][240]做了一帧缓冲，所有屏幕相关操作都是在这一帧上面实现的，使用DMA直接丢数据到FSMC接口上，比I/O快多了，然后就是资源的去背问题，所有的图片都是我从手机版上面截图下来的，然后背景色都是0X4DF9，然后因为jpg转换软件的关系，蓝色的背景色会有偏差所以直接判断把0x4df9不显示不可行，后来想到可以用RGB颜色来入手，虽然不是0x4df9但是还是蓝色，所以蓝色分量肯定比红色多，所以做了一个阈值判断(Roughly speaking, a large array [320] [240] is made in the external SRAM to do a frame buffer. All screen-related operations are implemented on this frame. Using DMA to drop data directly to the FSMC interface is much faster than I/O. Then it is the problem of resource backtracking. All the pictures are taken from the top of the mobile version, and then the background color is 0X4DF9. Later, because of the relationship between JPG conversion software, the blue background color will be biased, so it is not feasible to directly judge that 0x4df9 is not displayed. Later, I thought that RGB color can be used to start with. Although it is not 0x4df9, it is still blue, so the blue component must be more than red, so I made a threshold judgment, and then it is the transition between scene and scene.)
