步进电机的单片机控制，可以在Proteus下进行仿真

1、ps/2键盘输入，通过led显示ascii码 2、稍等1s可以在lcd上显示输入的字符 3、其中键盘上的backspce键是用来清屏的 4、当lcd上显示满字符时，在按下按键自动清屏，从第一行显示。-1, ps/2 keyboard input, through the led display ascii code 2, wait 1s in the lcd display characters input 3, which backspce keys on the keyboard was required to settle the screen 4, when the lcd display full of characters, the press the button automatically Qing-ping, from the first line of display.

实时时钟芯片DS1302采用串行接口，只需3根引脚便可以完成操作，其使用非常方便。这里采用AT89S52单片机作为外部微处理器，来对DS1302进行控制-Real-time clock chip DS1302 serial interface, only three pins will be able to complete the operation, its use very convenient. AT89S52 microcontroller used here as an external microprocessor to control of the DS1302
