I’m trying to do exactly what you did in your video, but have it display the sound in real time. For eg. to see the sound wave as you whistle. I’ve been having trouble trying find out how to do this or where to look for help.

Cheers

I am using Phidget interfacing hardware manufactured by Phidgets Inc.(http://www.phidgets.com). MATLAB has not yet developed an adaptor for it so I will have to make it myself.

I have to perform Real Time Data Acquisition and represent transitions in colors from Blue to Red when external pressure is applied on a Pressure Sensor which is connected to the interfacing hardware. The colors change in accordance with the magnitude of pressure applied.

How should I go about it and which toolboxes should I use in order to make this possible. Also, it would be Kind if you can let me know the various pdf resources I should definitely consult for same.

Kind Regards,

I’m trying to analyze the signal from a sensor that I have in my system. Do you know is there any way I could read the signal in the Matlab plot immediately while the sensor is capturing data?

You are better seeking technical support here:

The code I used is:

ao = analogoutput('nidaq','Dev2')
addchannel(ao,0)
set(ao,'SampleRate',100)
set(ao,'TriggerType','Immediate')
putdata(ao, 5); % put out 5V on analog output
start(ao)

Can you help me with this code please?

Thanks a lot for the posted videos; they are really amazing and helpful.

I am saving the data that i obtain from my NI DAQ card in a .daq file. This is the code snippet for it.
================================
ai.LogToDiskMode = ‘index’;
ai.LoggingMode = ‘Disk&Memory’;
ai.LogFileName = ‘data.daq’;
ai.logging;
================================

And this stores the file by default in the working directory. I was wondering if there is a way where the user can specify the location of the file he would like to store it in via a GUI.

Thanks for all your help Doug !
Appreciate it.
