Description: Multi-machine communication, design a multi-machine communication system based on MCS-51 series single-chip AT89S52' s. When the 1st and the 2nd machine-machine communication, the 1st microcontroller host, the 2nd machine as a slave. Data sent to the host computer through the serial port specified format from SCM, SCM and respond to the received data from the slave via LED digital display communication status. 1 MCU control the communication process through the matrix keyboard and display. This mode of communication is a master-slave mode, the host can only send a message to the slave. When the 1st and the 3rd machine-machine communication, there is no slave master points, is affirmative mode. The 1st machine can send a message to the 3rd through the key machine, the 3rd machine can also send information via the button to the 1st machine, display data communication through their digital tube, LED lights display the communication status.
