Please proceed as follows:

1) Purchase the book http://www.labviewforeveryone.com/wiki/Main_Page , study it carefully, and make sure you perform the exercises in the book seriously.

2) Install LabVIEW 8.6.1 or higher on your acquisition PC.

3) Download the example files from http://www.biosemi.com/download/BCI_Development_kit.zip

4) Open the Virtual Instrument ActiView700-Light-Rev4.vi and study the diagram (source code)

5) Open the Virtual Instrument ActiView701-Lores.vi, and study the diagram (source code)

6) Use either ActiView700-Light-Rev4.vi or ActiView701-Lores.vi as the basis for your BCI program. Modify the LabVIEW code as required for your BCI application.

7) Optimize the online response time of your BCI application by using the STRIDE function calls (controls the package size of the USB transfer). Open ActiView700-Light-Stride-Rev4.vi, study the code. Sent triggers to Trigger Input1, and monitor the delay to Trigger Output 1 with various STRIDE settings.

8 ) Include the STRIDE functions in your BCI program and fine tune as required. Low STRIDE values provide minimal delay at the cost of increased processor load. Find the optimal trade-off for your application.

Best regards, Coen (BioSemi)
