ELVIS Interface

ELVIS Interface

This EZ-KIT Lite board contains the National Instruments ELVIS inter- face. The interface features the DC voltage and current measurement modules, oscilloscope and bode analyzer modules, function generator, arbitrary waveform generator, and digital IO.

The ELVIS interface is a NI LabVIEW-based design and prototype envi- ronment for university science and engineering laboratories. The ELVIS interface consists of the LabVIEW-based virtual instruments, a multifunc- tion data acquisition (DAQ) device, and a custom-designed bench-top workstation and prototype board. This combination provides a ready-to-use suite of instruments found in most educational laboratories. Because the interface is based on the LabVIEW and provides complete data acquisition and prototyping capabilities, the system is ideal for aca- demic coursework that range from lower-division classes to advanced project-based curriculums.

Audio Interface

The audio circuit of the EZ-KIT Lite consists of an AD1871 ana- log-to-digital converter (ADC) and an AD1854 digital-to-analog converter (DAC). The audio circuit provides one channel of stereo input and one channel of stereo output via 3.5 mm stereo jacks. The SPORT0 interface of the processor is linked with the stereo audio data input and output pins of the audio circuit.
