Hello!
I would like to program a little GUI, that shows me the Analog-Modules of a connected cDAQ from NationalInstruments. As my cDAQ is only supported by the session based interface, I have to use how described in the help:
d = daq.getDevices
Now I get the Modul-Names if I type:
modulnames = {d.Description}
But now the question: I have some input and output-Modules and only want to list e.g. the input-modules in a list.
How could I get a cell-array that only shows me the names of the input-Modules?

Anyone has got an idea?
I type
names = {d.Description}
and get an cell in that I can find the strings 'National Instruments NI 9201' and 'National Instruments NI 9263' for example. The NI 9201 is an input module and the 9263 an output module.
So, I want to create in my GUI two popup-menus. On one popup-menu I only want to see the input-modules, on the other I just want to see the output-modules. Now, to see what are input-modules and what are output-modules, I could type
info = {d.Subsystems}
But then, I first get out
[1x1 daq.ni.AnalogInputInfo] and [1x1 daq.ni.AnalogOutputInfo]
In the workspace that is shown as another cell, but in each cell there is more than one information.
When I now type
info{1,1}.SubsystemType
I get the string 'AnalogInput' - but only for the first device. How could I get this string for all the devices in one step so that I can make a difference between input and output modules?
