Data Latch with Push Button

[#1]

Overview
This example demonstrates how to acquire a continuous amount of data (Waveform) using the DAQ device's internal clock.

Description:
This is a very basic example intended for newer users of LabVIEW.  The example allows the user to push a button and "latch" or "store" the signal data acquired from their data acquisition device.  The techniques used in this example could be potentially useful if the user was looking to save data at a particular time, but keep data acquisition continuous.  Also, rather than using an array indicator to view the data, the user could go a step further and store the data in some other format (i.e. spreadsheet, text file, etc.) in the "True" case of the example.

When the Latch Data button is pressed, the code stores the specified number of samples in the Samples to Read field into the Array of Data array.  Each time the user presses the button, the previous data will be overwritten.

Steps to implement or execute code
To implement this example:

1. Define the Physical channels to be used
2. (optional) Set the rest of the parameters as needed
3. Run the VI and Use the Latch Data Button as it runs
4. (Optional) Turn on the Highlight Execution to see the flow of the VI

To execute this example:

1. Install the required software.
2. Connect the DAQ hardware that supports the Analog Input features
3. Confirm the connection with the MAX with TestPanel
4. Open the VI and refer the Implement Steps

Requirements
Software
LabVIEW 2012 or compatible
