我用的是74HC154做行驱动（A=P1.7 B=P1.6 C=P1.5 D=P1.4) 用两个74HC595级联做列数据显示（DS=P2.5 存储时钟STCP=P2.6 位移时钟SHCP=P2.7) 单片机为：STC89C52
点阵屏为16*16共阴接法。程序呢要分两种：第一种是一个字一个字的显示：科技改变生活，这六个字；第二种是：往左慢慢移动显示这六个字。呵呵呵，要求是不是有点多呢，先谢谢各位高手们啦啦啦！还有接口定义是否符合要求呢？.......希望在单片机学习路上得到你们的指导！哦，程序最好能有文字注明哦，我真的看不懂C程序的流程呀呀呀！呵呵希望拿到的程序就能上机显示，自己实在很菜呀呀！期待中......
符合再加分！！！！
