【摘要】 介绍了无线指令系统的工作原理,以及串口通信在该系统中的重要地位。分析了W in-dows32环境下的串口通信的实现机制和几种实现方法及其编程思路,并以V isual C++6.0为开发平台,通过调用W in32 API编写了计算机的异步串口通信程序,用汇编语言编写了单片机的通信程序。最后结合无线指令系统实例,实现了PC机串口与单片机之间的数据通信,通信效果良好。更多还原

【Abstract】 The paper introduces the operational principle of wireless command system and the important position of serial port communication in the system,and analyses the realization mechanism of serial port communication in Windows32,kinds of realization methods and programming ideas.Based on VC++6.0,the asynchronous communicational program on computer compiled by transferring Windows32 API,and the communicational program on single chip compiled with assemble language,combining the example of wireless command system,realize the communication between PC and single chip.The effect of communication is very good.更多还原
