基于LabWindows串口通讯设计

Design of Serial Communication Based on LabWindows

LabWindows/CVI是NationalInstruments公司(美国国家仪器公司,简称NI公司)推出的交互式C语言开发平台。串行接口简称串口,指数据一位一位顺序传送。其特点是通讯线路简单,只要一对传输线就能实现双向通讯,从而大大降低成本,适用于远距离通讯。基于此,以LabWindows/CVI软件平台为基础,分析了RS232接口的串口通讯的设计过程,主要为实际工程应用提供设计思路。

LabWindows/CVI is an interactive C language development platform launched by National Industries(National Instruments Corporation,NIC).Serial interface is referred to as serial port and refers to data transmission one by one.It is characterized by simple communication lines,which can achieve two-way communication as long as a pair of transmission lines,thus greatly reducing costs and applying to long-distance communications.Based on this,based on the LabWindows/CVI software platform,the design process of serial communication of RS232 interface is analyzed,which mainly provides design ideas for practical engineering applications.
