  1. /******************************************************************
  2. 功能：LED16*16点阵滚动显示
  3. 说明：74LS164用作发送数据，P0,P2口用来列选
  4. 看本程序最好的工具最好旁边有标号和语法着色，推荐keil或UltraEdit
  5. 懒人提示：要改成自己所要的显示内容，要怎么改？
  6. 1.要改显示内容改第23~92行代码，还有第119行代码，具体改法见下面注释
  7. 2.要改滚动速度改第102行代码
  8. *******************************************************************/
  9. /*头文件*/

  15. /*函数声明*/
  16. void delay();
  17. /*全局变量*/
  18. uint lie; //列选标志

  20. /** 字模:反显，纵向取模，开头和结尾均加入32个0xFF，用于改善屏滚动显示时循环的连贯性   **/
  21. /** 北京市公交公司 T8 路,开往北京西站,发车时间20:30,欢迎大家乘坐！  --  **  宋体, 12  **/
  22. /** 当前所选字体下一个汉字对应的点阵为:  宽度x高度=496x16,  调整后为: 496x16          **/
