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 mainfr a me can experiment. The above procedure is very simple function is to host regular rotation and sent several 55H initials, mainfr a me and sent to a number of P1 mouth.
