Multithread Read Serial Data, Display and Write to Spreadsheet Using LabVIEW

[PeanutButterOven]

Overview

MultiThreaded application to read, graphically display and write serial port data to a spreadsheet file.

Description

This VI creates a multithreaded application that reads continuous packet data transferred over a specified Serial (COM)  port while continuously displaying the data graphically and writing the data to a file. In this example, the data is from an accelerometer with a fixed packet length. The contents of the packet are Header, Data, CheckSum (comma delimited HEX values)

[4bytes][XData][YData][ZData][CHKSUM]

Once the Data is read from the COM port it is put into a thread safe queue for the second thread to process it.

Requirements

• LabVIEW 2013 (or compatible)
• Serial Instrument

Steps to Implement or Execute Code

1. Create a serial packet like the example below from the serial instrument.

               Serial Packet from serial instrument: FFAADDFF,5D,A6,55,CHKSUM

    2. Configure the serial instrument by inputting strings below the Waveform Chart.

    3. Check the Packet Data indicator and Chart.
