Changing the Sample Rate in the code for 16-channels back to 250 Hz

ECE_Engineer · July 2018

I've already made a handful of edits to the OpenBCI GUI code in order to change the sampling rate to 250 Hz.

e.g. fs_Hz to 250, Nfft to 256, etc.

I'm wondering if anyone knows what edits need to be made in order to achieve this?

Thanks!

Cyton + Daisy can sample faster with the Wifi shield, or saving to the SDcard. But cannot sample faster than 125 hz using the dongle, because of bandwidth limitations. The radio packets alternate, each with 8 channels.
