Generate PWM signals on cRIO analog output module

[HunterSeeker]

Overview

This example shows how you can use the "Square Wave Generator" express VI to generate PWM signals with an analog output module on CompactRIO.

Description

This example shows how to use two instances of "Square Wave Generator" express VI to generate two PWM analog output signals with the following parameters: Frequency, Phase Offset, Amplitude, Offset, Duty Cycle.

All parameters can be canged in host VI Front Panel that can be used in Real-Time debugging mode or on windows targets. Parameters in host VI can be entered in Hz (Frequency), Periods (Phase Offset, Duty Cycle) and Volts (Amplitude, Offset). By using the "Normalize Signal Generation Parameters" VI, all parameters are converted and scaled to datatypes required by the FPGA functions.

Requirements

 Software

• LabVIEW Full or Professional Development System 2012 (or compatible)
• LabVIEW Real-Time Module 2012 (or compatible)
• LabVIEW FPGA Module 2012 (or compatible)

 Hardware
