Hi!

I'm trying to collect EEG data using g.tec amp 32 channels through LSL. I opened the APP for g.tec, where 16 channels are setup up for default. When I try to modify the number of channels (including the channel labels) it is not possible (the GUI object for that "number of channels" is blocked ). See the picture:

I tried to modify the file "gUSBamp_config.cfg" adding the channel labels and the number of channels, but when i run the app appear the labels but the object remains blocked with the number 16.

can anyone tell me if with the current LSL APP is possible recording 32 channels?

Now, I'm making a script for collecting the data from g.tec and push it in the LSL. (an update of it coming soon).

Really, i will appreciate a lot your help, I don't want spend more time on it.

Thank you.

I will have to check the code, but it appears that the app can only support 16 channels.

I've created a new g.Tec/g.NEEDaccess application that can now support multiple g.USBamps in master/slave. There are some reasons why one might want to use the direct API instead of the server/client g.NEEDaccess API, so I don't consider this issue solved, but at least there is an alternative for now.

@cboulay Is your gUSB.amp app ready so I can close this?

cboulay commented 5 years ago

Nope! There's still a buffer problem at high sampling rates. I haven't had time to get back to it recently. Feel free to move the issue to labstreaminglayer/App-g.Tec

Hello, I don't know how to compile the APP for g.tec, Do you have the compiled app for the g.tec client? Could you do me a favor?

cboulay commented 4 years ago

It's on the release page: https://github.com/labstreaminglayer/App-g.Tec/releases It requires the g.NEEDaccess SDK from g.Tec.

If you don't have g.NEEDaccess but you have a g.USBamp and the very old drivers for that then you can will have to compile the gUSB app.

If you have any further questions then please open a new issue.

Thank you very very much! It's kind of you. Okay
