利用LabVIEW设计Palm与单片机间多通道串口通信的方法

针对目前串口通信的研究大都只停留在PC机与单片机之间，或只用文本语言开发PDA与单片机的串口通信这一现状，研制了一套以PIC16F873为下位机，Palm OS为上位机操作平台，LabVIEW7．0为开发语言的串口通信系统。给出了该系统的硬件、软件设计方案及模拟测试结果。实验证明其工作性能稳定、界面友好、用户操作方便。

The Realization of Multi-channel Serial Communication between Palm and Microcontroller Based on LabVIEW

Current research of serial communication is merely between PC computer and microcontroller. Also, the serial communication between PDA and microcontroller is developed with text style language. We developed a serial communication system which takes the PIC16F873 as the sampling machine, Palm OS as the supervisory computer and LabVIEW 7. 0 as developing language. This paper provides the hardware and software design scheme and simulated test result of the system. The experimental results prove that this system provides stable performance, friendly interface and convenient operation.
