Proteus simulation of single-chip machines communication system
Abstract:SCM can now say that the Hundred Flowers period, the world's major chip manufacturing companies have launched their own microcontroller, from eight, 16-32, numerous, everything, that is compatible with mainstream C51 series, there are not compatible but they are distinctive, mutual complementary, providing a vast world microcontroller applications.
This paper focuses on the multi-SCM master-slave multi-machine communication system configuration, wherein the machine with the same authority. The host can send a signal to the machine, you can accept the signal. Through modeling and simulation Proteus let function implementation. The design of the difficulty is how to make more than one microcontroller to communicate with each other at the same privileges, and can be sent from slave to master information summary.
This study has been through simulation, real feasible. Has a certain error detection capability, bit rate serial communication is 9600bit / s, the communication speed, and high reliability. In this study, the hardware circuit to solve the master and slave machines communicate with each other between the slave and slave communicate between machines.
Keywords: MCU; Multi machine communication; master-slave mode
