摘要
单片机串口通信已被广泛地应用于通信、控制、监控领域。为使操作系统的软件设计标准化,降低软件开发的难度,并提高单片机的利用率,串口接收机选用51单片机串口作为通信的设备,实现以中断方式接收到外部发来的命令,对命令进行分析并做出应答的功能。设计使用了Small RTOS51实时操作系统,程序设计结构清晰,用户只需更改设计中的应用任务就可实现各种应用的串口通信协议。重点介绍设计方案及软硬件的设计。该系统使用Proteus进行仿真实验后,效果良好。
The MCU serial communication has been widely used in communication, control and monitoring field. In order to make the operating system＇s software design standard, the serial port receiver uses 51 MCU as the communication device. It not only reduce the difficulties of software development, but also improve the utilization of MCU. The 51 MCU receives the orders from out by interrupting mode, then analyzes the orders and reply. This design uses Small RTOS51 real-time operating system. The structure of program design is clear. Users only need to change the application tasks of design to realize the serial communication protoeal of several. Details introduces the design scheme and the design of software and hardware. This system uses Proteus to simulate and gains good test results.
