Re: Issues generating the code

For openBCI, I found some interesting information on their website. It seems that openBCI is sending data in a very choppy manner until the COM port is reconfigured as described here: https://docs.openbci.com/docs/09Deprecated/OpenBCI_on_WindowsDep I see the page is deprecated but could not identify...

Re: Issues generating the code

I am not sure what you mean. There is no sense in making SampleBlockSize less than what hardware/software outside BCI2000 can deliver. All BCI2000 blocks should have the same length, apart from a little variability.

Re: Issues generating the code

I guess that block duration switches between zero, and a multiple of 32ms, right? This happens when there is a hardware/software buffer involved with a length corresponding to a multiple of 32ms. That buffer is outside BCI2000. When it is full, data may be read without delay, for multiple software b...

Re: AmpServerPro OnAutoConfig

Emanuel,

it would be helpful if you could test the AmpServerPro source module with a standard configuration, e.g. P300 speller or SpectralAnalysis, so we will know whether it is related to the FieldtripBuffer signal processing.

Thanks,
Juergen

Re: AmpServerPro OnAutoConfig

Emanuel,

I have no idea what could cause the issue. Can you tell me the "old" and "new" versions of BCI2000 for which it works and doesn't, respectively?
I have no EGI amplifier to test, but I can submit a ticket for this issue to look into as soon as possible.

Best,
Juergen

Re: Issues generating the code

BufferedADC adds multithreading to GenericADC. It does not change requirements for SampleBlockSize. Any constraints on SampleBlockSize and SamplingRate are imposed by module code that inherits either BufferedADC or GenericADC. Typically, such constraints are due to hardware limitations, so changes t...

Re: AmpServerPro OnAutoConfig

You might need to set SourceBufferSize to a larger value, e.g. "2s".

Re: AmpServerPro OnAutoConfig

Hi Emanuel,

mixing core modules from different BCI2000 versions should work, but the Operator module needs to match the most recent core module version. Otherwise, BCI2000 will not work properly.

Re: Issues generating the code

Did TortoiseSVN successfully complete the entire checkout of BCI2000? If in doubt, right-click the BCI2000 folder, and choose "SVN Update" from the context menu. Then, rerun CMake.

Re: Issues generating the code

Did you move or rename the BCI2000 source code directory after running CMake?

Re: Issues generating the code

Hi, could it be that the path to your BCI2000 source code contains special characters? After all those years, CMake and/or VisualStudio still choke on them.

Re: AmpServerPro OnAutoConfig

What does it say when it does not accept "auto" as input?

Re: AmpServerPro OnAutoConfig

Emanuel,

OnAutoConfig() sets all parameters that are set to "auto". E.g., if you set SourceChGain to the single entry "auto", SourceChGain will assume the correct number of entries, and values.

Re: LSL Support?

3.05 is still the latest release. 3.6 has been underway for quite some time now, but never made it to an official release. This may have to do with heightened quality requirements which are in place from 3.6 onwards.

The LSLSource module is now available at /src/contrib/SignalSource/LSLSource.
