ELVIS Interface
1-12 ADSP-BF538F EZ-KIT Lite Evaluation System Manual
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.
