Serial port communication system based on LabVIEW passive receiving type本发明提出了一种基于LabVIEW被动接收型的串口通信系统,包括外界通讯模块,触发模块,串口基本通信模块,数据检测和重测模块和数据存储模块;外界通讯模块通过两个共享变量与外部控制器实现通讯,触发模块根据外界通讯模块传入的触发共享变量数据值进行判断...
and run the FPGA VI programmatically from the Real-Time VI using the Open FPGA VI Reference or Run Method, make sure that a considerable delay (at least 2 seconds) is left between the moment when the FPGA VI starts running and when the serial communication is opened with the NI-VISA VIs...
Connect the instrument’s port to the NI serial interface device or the computer’s port via a serial cable and power it on. If you have a two-wire RS-422/485 instrument, refer to Set Up 2-Wire (Half-Duplex) Communication with RS-485 Port. Configure Hardware in MAX In Measurement and...
