Brainflow sample order from get_board_data() ?

Hi All,

I have the cyton+daisy that connects to Windows 10 via the dongle. I retrieved data samples from the board by calling BoardShim.get_board_data() belonging to Brainflow’s Python version. My questions are
1. is the order of the data samples guaranteed to be preserved, i.e. the order is the same as the one sampled by cyton?
2. is it possible to get the ID of the incomming data samples or their timestamp that are given by cyton?

Best,
vattha

    Vattha, hi.

    Yes, the sample order is always preserved. Time stamps returned by Brainflow are NOT generated inside the Cyton, but are only assigned when the radio / usb buffered samples are received at the laptop. So these times are only approximate and subject to OS, IO, buffering delays.

    Best channel for asking Brainflow questions is on the Slack, register with link on this page:
