1、 实现单片机和PC机的串行双工通信，单片的P1口接一LCD，要求PC键盘每按“0~9”数字键能发送到单片机上，并显示在单片机接的LCD上；单片机发送一串字符串能显示在PC的屏幕上-1, and PC-MCU serial duplex communication, the P1 port received a single LCD, PC keyboard required every press " 0 9" digital keys to send to the mic

在keil平台下写的单片机双机通信的程序。读者可根据收发数据的多少修改程序。-SCM dual-machine communication

单片机的双机并行通信例程，可以实现双击的双向并行通信，通信稳定可靠-Single-chip parallel communication routines, two-way parallel communication can achieve double, stable and reliable communication

can双基通信的简单测试程序，STM32F103ZET6的单片机(CAN duplex communication based on stm32f103 is easy to understand and popular)
