将程序编译通过，写入芯片，插入实验板，用通读电缆将实验板与主机的串口相连就可以实验了。上面的程序功能很简单，就是每隔一段时间向主机轮流送数55H和AAH，并把主机送去的数送到P1口。-procedures to compile and write chip, insert experimental boards, reading the cable will be used experimental plate and serial port connected to the mainframe can experiment. The above procedure is very simple function is to host regular rotation and sent several 55H initials, mainframe and sent to a number of P1 mouth.
