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

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


Updated 01 Sep 2016

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

% --- Digital Multimeter ---
dmm = elvis.Multimeter('dcvoltage');
dmm.Range = '10V';
data = dmm.readData();

% --- Digital Multimeter with auto-ranging ---
dmm = elvis.MultimeterAuto('dcvoltage');
data = dmm.readData();

Is there any way to get this to run on a 64 bit MATLAB install?


First download 12/14/2018 by some guy sitting in his dorm room at 6:15 A.M for use on his own board. Makes me think about how much better my classes could be.
Anyway, thanks for this one team!
