16 channel data sample rate ( = 125 sps )

jarek · January 2015

Hello All,

The documented data sample rate is 250sps. I was able to measure and confirm that with 8 channel board alone.

But when I connect Daisy module, which makes it 16 channel system, the amount of transferred data is still the same.

Which means, that now the sample rate per channel is just 125sps.

Is this correct?

I think 115kbs serial port speed would not allow for more to transfer. But I though I should ask to clarify.

Thanks

Jarek

Jarek, hey great to see you on the forum here(!)

Thanks again for adding the OpenBCI board drivers to BioEra. You and @georgemartin both.

That was definitely a cool trick you did, being able to bypass the FTDI driver and using your own.

Regards, William
