Overview
The example demonstrates the generation of a continuous pulse train that could be configured in its frequency parameter of it

Description:
This example is a slight modification of the "Gen Dig Pulse Train-Continuous.vi" example available in the LabVIEW Example Finder. In this version, the front panel control for frequency will be polled every loop iteration and the pulse train will be modified to reflect the new frequencies. This example employes a local variable in order to both set the initial frequency as well as to continuously update the output each loop iteration.

Steps to implement or execute code
To implement this example:

Set the physical channel of the counter
(Optional) Define the rest of the parameters as needed
Run the VI
(Optional) Turn on the Highlight Execution to see the flow of the VI

To execute this example:

Install the required software.
Connect the DAQ hardware that supports the Counter features
Confirm the connection with the MAX with TestPanel
Open the VI and refer the Implement Steps

Requirements
Software
LabVIEW 2012 or compatible
NI-DAQmx 16.0 or compatible

Hardware
cDAQ with C series Counter Output Module
