ADUC824串口通信，可实现与上位机通信，用T2定时器作为波特率发生器-ADUC824 serial communication, enabling communication with the host computer, as a baud rate generator with timer T2

模拟串口程序 占用T0 或者T2 波特率9600 起始位 1位()

串口的调试和传输 用于两个串口间的发送与接受(Serial port debugging and transmission is used for sending and receiving between two serial ports.)
