AT89C52的组合按键识别程序,已经调试成功-AT89C52 combination of keys identification procedures have been successfully debug

是液晶显示屏的驱动程序，很好的啊-LCD display driver, very good ah

根据键盘的控制，移动字符串Hello或者华东师范大学,行列键盘的7用于字符串左移,8用于字符串下移，9用于字符串右移，5用于字符串上移。按键每按一下向各自的方向移动一个点阵的位置。-Under the control of the keyboard, move the string Hello, or East China Normal University, the ranks of the keyboard for the string to the left of 7, 8 for string down, 9 for string shifted to right, 5 for the string to move. Click the button for each move to their respective location of a dot matrix.
