NI ELVIS II Power Supply, Function Generator, Digital Multimeter Support

MATLAB library that extends support for communicating with a NI ELVIS II prototyping platform

The NI ELVIS II is an electronics prototyping platform with analog and digital I/O and several built-in laboratory instruments.

Starting with R2010b, Data Acquisition Toolbox supports the analog and digital I/O subsystems on ELVIS II.

This submission extends the base support, and allows you to access the following built-in instruments directly from MATLAB:

* Variable Power Supply

* Function Generator

* Digital Multimeter

The following Multimeter measurements are supported:

* DC Voltage

* AC Voltage

* DC Current

* AC Current

* Resistance

* Diode

* Continuity

Sample usage:

% --- Configure variable power supply ---

vps = elvis.VarPowSupply;

vps.Vpos = 5; % set the positive supply to +5V

vps.Vneg = -9; % set the negative supply to -9V

% --- Configure Function Generator ---

fg = elvis.Fgen;

fg.Function = 'triangle';

fg.Amplitude = 4; % set amplitude to 4V

fg.Frequency = 2; % set frequency to 2 Hz

fg.start();

pause(1);

fg.stop();

% --- Digital Multimeter ---

dmm = elvis.Multimeter('dcvoltage');

dmm.Range = '10V';

data = dmm.readData();

% --- Digital Multimeter with auto-ranging ---

dmm = elvis.MultimeterAuto('dcvoltage');

data = dmm.readData();
