Overview

Examples of how to both simulate and demodulate a resolver signal using LabVIEW FPGA on CompactRIO and PXI.

This LabVIEW example has examples of resolver simulation and measurement on both Windows and FPGA targets.

Resolvers produce a sine / cosine signal that is modulated with a carrier frequency. Decoding the sine and cosine signal is done using the arc-tangent function available in LabVIEW FPGA (which uses a cordic algorithm).

Simulation in the example produces an excitation signal (carrier frequency) and sine / cosine signals based on a input position in degrees. Fixed point math is used.

In the FPGA examples, 1 cycle of the carrier frequency sine wave is generated from the host VI and stored in a LUT (Look Up Table) in FPGA. The sine and cosine values are multiplied by the LUT values to create the appropriate modulated output signal.

LV 8.2  - Mar 31, 2010

Is there any way i can get this code for LabVIEW 8.2 instead of 2009? Thanks!
