Analog Discovery Studio MATLAB add-on

[Erkang]

Hi, We bought Analog Discovery Studio. It works fine with the waveform software. But the MATLAB R2016a cannot even identify this devise. I have "Data acquisition toolbox" and "Data Acquisition Toolbox Support Package for Digilent Analog Discovery Hardware" installed. Could you tell me what else should I install in order to have matlab identify Analog Discovery Studio?

Thanks a lot

Hi @Erkang

The Analog Discovery Studio should be supported by MatLab 2018a. The ADS has identical device ID to AD2, only the device variant is different.

The DAQ toolbox support package filters the devices based on ID. That is why MatLab 2013a supported only the AD(1).
In 2018a AD2 was added. I don't think MatLab support looks for variant ID, so it should work with ADS too.

Thanks a lot, @attila

I use the code you attached to acquire data from two oscilloscope channels, I checked the available analog channels using 'FDwfAnalogInChannelCount' , it shows there are 2 available channel. But after configurate the device using 'calllib('dwf', 'FDwfAnalogInConfigure', hdwf, 0, 1)', all the output of one oscilloscope channel have the same value, -0.0026. All the output of another channel have same value of 0.9906. I even commented out the ''FDwfAnalogInConfigure', but the outputs of two osc channels still remain the same. So I think the device configuration command does not take any effect. So that osc channel 0 only have low voltage output, osc channel 1 only has high voltage output. Could you tell me why this configuration command does not work? I even tried to use logical(0) and logical(1), instead of 0 and 1, as the input arguments. But that does not fix the problem.

Never mind, it is fixed. One input data type was wrong
