BCPy2000 timer

Post by dhruv aggarwal » 13 Jul 2011, 22:41

hi
I also wanted to know if there is any variable defining a timer during the run in BCPy2000. I need to use a timer which starts from 0 at the beginning of the run and continues until the run is suspended.

Kindly help.

Hi,

the BCPy2000 Process hook is called once for each sample block acquired from the EEG system. To get a timer in units of sample blocks, define a variable and increase it by 1 from inside the Process hook.
To convert sample blocks into seconds, multiply by the SampleBlockSize parameter, and divide by the SamplingRate parameter.

HTH,
Juergen
