由于普通单片机只有一个串口,由于用户可能会用到多个串口,而对于双串口的单片机价格贵,不如自己动手选择两个IO口,自己模拟串口通讯,以下为模拟串口程序.-Because there is only one common single-chip serial port, as the user might use multiple serial ports, dual serial ports for the price of your microcontroller, it is better to select two IO own mouth that they simulation serial communication, the following for Simulation of serial procedures.
