Recording to SD for >24 Hours

BCoughlin · April 2019

Hi,

I am using the Cyton and connecting to it using the Python code.

I was wondering what would be required to set the Cyton to record to SD for a duration longer than 24 hours.

I skimmed through the code, but could not find where the preset SD recording times are set. I assume that it is in the firmware, based on the Cyton SDK doc page.

So, maybe it would be a matter of setting one of the unused ASCII characters to initiate SD data logging for, say, 36 or 48 hours? Then I send that character from Python after establishing a serial connection.

Would I need to do anything else?

Related - MATLAB has some difficulty opening the 24 Hour recordings, would it be possible to record to a new file on SD every X hours? I'd be okay losing a small segment of data when that happens. I'm not sure how involved (or realistic) adding that functionality would be, though.

Thanks for your help!
