Configuration comm for National Instrument NI DAQP ad 6016

[pjercic]

I can't seam to connect my BCI2000 with National Instrument NI DAQP ad 6016. I just want to set up a single channel for start.
It might be a configuration issue, since I get the error

2014-08-25T11:22:14 - Operator set configuration
2014-08-25T11:22:14 - SignalProcessing confirmed new parameters ...

I am using NI DAQmx to connect to my device and it acquires the signal perfectly, so the driver is good to go. The specifications of the NI DAQmx installation are as follows.

It looks like there were some parameters that were hard-coded into the module. You'll have to change them and recompile.

Open up BCI2000\src\contrib\SignalSource\NIDAQ-MX\NIADC.cpp

Search for

Code: Select all

long int terminalConfig=DAQmx_VAL_RSE;

.
(In my file it is line 413)

Change it to read

Code: Select all

long int terminalConfig=DAQmx_Val_NRSE;

or, if you are doing bipolar recording, use

Code: Select all

long int terminalConfig=DAQmx_Val_Diff;

.

I found the mentioned spot and changed it, but QT library is bugging me when trying to recompile. I have QT installed on my system, but the system says it can't find the internal QT libraries when I run Make VS10 Project files.

Can you please recompile this module (EXEcutable) for me, or advise me on how to fix the recompilation issues with QT.

[pjercic]

In more detail, after running Make VS10 Project Files I get the following error, I have installed QT:

3DAPI/Demo/CMakeLists.txt:31 (QT4_WRAP_CPP):
Unknown CMake command "QT4_WRAP_CPP".

p.s. I did found the solution which I quote bellow, but I couldn't force CMake to look for localy installed QT

When running CMake, it determines the current compiler/OS combination, and tries to download an appropriate version of the BCI2000-specific Qt build. If no such build is available, it expects a local Qt installation to be available, and fails with an error message if this is not the case.

If a BCI2000-specific Qt build is available for the current configuration, you will still have the option of using a locally installed version of Qt. This is a CMake option USE_EXTERNAL_QT appearing in the CMakeCache.txt file after CMake has been run for the first time. Such options may be changed using the CMake GUI, or a text editor. After changing the option, run CMake again to apply the change to the created project files.

Sorry for the delay.

I was able to compile using revision 4730. I had to fix some LibTiny errors first.

I tried using an older revision but I had the same Qt errors as you describe.

See attached.

[pjercic]

Wow, thanks for the help and the modules.
When I saw "DLL Hell" mentioned together with QT library, I was only expecting problems.

I am able to hook to the NI DAQP ad 6016 device, I can see the Active LED turned ON and the source module is running in NRSE mode.
I have connected one of the input channels to my sound card, which I can clearly acquire in the NI MAX and Signal express. Unfortunately, I can't get any signal reading away from the baseline, in the Signal Source display.
That is, all channels report 9.830100e+001 value all the time. Shouldn't there be a slight fluctuation of the signal even if nothing is connected to it, just because of the imperfection of the amplifier?

[boulay]

It's not unusual to be flat if it's railing. However, that's a problem at the input. if you have a signal in NI MAX then you should see a similar signal in the signal source visualization.

Is your sound card outputting something sufficiently slow that it won't get filtered out by any filters that might be built in to the signal source module?

Sorry, I don't have any NIDAQ devices so I can't help you test.

[pjercic]

Thank for helping out.
I don't believe that my signal is railing, you can see in the images I attached, my signal is between 0 and 1 volts with 220Hz stimulus (there is also 50Hz there since it comes of the sound card).
You can perfectly see the signal in the NI software, but in BCI2000 the line is flat even on the muV scale.
I measured in differential and nrse mode where I could get a clear signal in both on NI software.

Can you please take a look and advise me on how to proceed further in fixing this, any advice is good.

[boulay]

Have you ever had BCI2000 working with another module (even SignalGenerator)? If so, then I guess that your problem has to do with the NIDAQ module. I've never actually used any NIDAQ module, and I don't have a NIDAQ device so I cannot test.

Do you have access to any other NIDAQ devices that you can try?

You may need to do a little coding to fix it. If you do manage to fix it then please let us know and we will set you up to submit your changes upstream.

At the top of the NIADC.cpp file there is the contact information for the person that developed it. You might get better insight from him, but I don't know if that 6-yr-old institutional e-mail address is still valid.

Good luck.

I have BCI2000 working with the signal generator and I used NIDAQ device ad 6016 to test the NIDAQ module, the screenshots were made using that device and the signal from the audio sound card.

I will try with the contact details, before proceeding to solving the problem programmatically.

[pjercic]

Is there a way to run this module in DIFF mode, instead of NRSE?
I managed to prepare the signal in DIFF mode correctly, so if I get the module to work in DIFF mode I could get the correct signal.

[boulay]

In the zip file (a few posts up) I included a diff version of the module.
Note, however, that it's possible the changes I made to LibTiny are the reason for your flatline problem, and will thus may also cause a problem using the diff module. I have no idea if my changes are the cause or not. I don't see how, and I don't intend to investigate because the primary BCI2000 developer should be back soon and he will likely make his own changes that will overwrite whatever I have done.
