嵌入式系统ucos如何移植到c51单片机，重点解释了局部变量的覆盖问题和函数的再入性问题。...

本程序功能是利用单片机控制用户板上的小键盘，将按下的键通过单片机的串口发送给PC机，在PC机串口助手显示出来。用行翻转法的方法来识别输入的键盘。 二、通过单片机将键盘按下的键在LCD上显示出来。 -This procedure is the use of single-chip control functions of the user on-board a small keyboard, the keys will be pressed through the single-chip serial port sent to the PC, the PC Serial Port assistants displayed. Line inversion method used to identify the method of keyboard input. Second, through the single-chip microcomputer keyboard keys pressed on the LCD display.
