Re: Triggers via PsychoPy Mislabeling in ActiView

Hi, I usually make my code in c so I am not 100% sure if this is exactly the same in python. In order to sent a valid trigger you should send a single byte for example 0x01 and then wait for two times the sample rate before sending a new trigger, with the default sample rate of 2khz you should wait ...

Re: send trigger using Arduino

Dear Hyejin, The Biosemi USB Trigger interface or the Biosemi Presentation cable is not needed to connect a Arduino to the trigger connector of the USB-receiver. The trigger in/output port of the USB-reveiver is a sub-D37 TTL 5V compatible connector. In order to send a trigger you need to connect pi...

Re: Problem with trigger interface

Hi Joe, What brand and model of the parallel port are you using? And did this exact setup worked previously without problems? If all the triggers are low with the stimulus computer off then the Biosemi USB receiver is working as it should. So the problem is most likely within the stimulus computer o...

Re: TCP/IP connection

With the acquisition running you have to press stop (top left) and then select the required channels and press start again. Screenshot from 2021-05-31 12-32-31.png After that you can connect with the matlabclient. The matlabclient should be configured to 64+7=71 channels. Best regards Biosemi (Gerben)

Re: TCP/IP connection

Hi,

When the acquisition is not running you can select which channels you want to transmit over the tcp/ip link under the bracket "TCP subset"
How many channels did you select to be transmitted in Actiview?

Best regards

Do i understand correctly that the Matlab client receives the data normally but Actiview does not show that the matlab client is connected?

Re: send ECG data measured by Biosemi to another device.

We don't have a program to send the data directly from Actiview to an arduino. But we do have a tcp/ip streaming option in actiview where you can write your own program around to achieve this, the programs my colleague linked to are open source programs that you can use as an example to make your ow...

Because the LabView Runtime Engine 8.5 is only available in 32bit, Actiview for linux is also only available in 32bit. This unfortunately means that Actiview for linux can only work with the 32bit version of the driver. Actiview should have a 32bit copy of the driver(liblabview_dll.so.0) included in...

Re: ActiView on Linux: file missing

That is strange.
On my system ActiView defaults to /usr/local/lib/ for the libraries.
It was not necessary to change any environment variable.

Did you install both the "labview85-rte-8.5-1.i386.rpm" and the "labview-rte-aal-1.1-1.i386.rpm" from http://www.ni.com/download/labview-run- ... .5/868/en/ ?
The Libraries that you are missing should be in the "labview-rte-aal-1.1-1.i386.rpm" install file.
