在LabVIEW中利用动态链接库实现串口通信

The Implementation of Serial Communication With Lab VIEW Based on Dynamic Link Library

针对在LabVIEW开发环境下VISA控件串口通信方式的不足,提出了另一种控制方法,即在LabVIEW中通过直接调用通信用动态链接库库函数(如MOXA的PCOMM.dll),实现对计算机串口的通信控制,并结合焓差试验室的数据采集系统给出了实例。

Aiming at the demerit of VISA controls in Lab VIEW for serial communication, another kind of control method is proposed, that is through calling dynamic link library functions(such as MOXA PCOMM.DLL) for the communication directly, and the instance is given by using the method in data acquisition system for an enthalpy method test laboratory.
