Hi there,
I'm using cyton board and using the data automatically used as text file. And in this case, the sampling frequency is fixed to 250 Hz, anyone can suggest how to change this frequency, for example, to 125 Hz? Thank you for answering.

    Doris, hi.

    The sample rate is fixed at 250 Hz for 8 channel, and 125 Hz when Daisy is attached.

    In the past, other rates could be set when the Wifi Shield was attached. The Shield is currently out of stock, pending some minor power supply regulation adjustments.

    Hi everyone.
    I've just started working with the OpenBCI hardwares and softwares. In particular I'm working with CytonDaisy Board (with USB dongle) which samples data at 125 Hz. However I would need a higher sample rate of at least 250 Hz.
    Is there a way to change this sample rate and make it higher?
    Many thanks in advance.

    @silvia, hi.

    I merged your question into this existing recent thread. See previous comments. Easiest thing for you to do is to remove the Daisy. That will give you 250Hz.
