 * @brief 墨水屏 驱动库函数 源代码模板
 *        使用前, 先查找替换 template 改为你需要的驱动名称
 *        比如3英寸的屏幕驱动程序应该叫 guy_dev_300a
 *        此时需要将 template 替换为300A.
 *        替换好之后, 改文件名, 大小写也要注意改 (文件名最好不要出现大写)
 *        最后把这个brief替换掉

  若设N=(((屏幕宽度+7)/8)*屏幕高度), 则n的取值范围为 0<=n<N .
  比如一个缓存buffer, 有N字节, 那么可以用f(n)=buffer[n] 
  函数语法为 drv_dispWriter([&](int n)->uint8_t{return buffer[n];},3);
  呃 你就把里面的f(n)理解为buffer[n]就行.
