Hi,
when we use the uSD only (no WiFi or other wireless) what is the fastest acquisition/sampling rate for:
a) 8 channel Cyton
b) 16 channel Cyton
In both cases how do we configure it for uSD AND the fastest rate?
Thank you
Rick
This pull request is relevant. I asked for it to be examined and prioritized for acceptance. But never heard back. Can you expedite the perusal of the code changes? They are minor.
@rick123, hi. Even without the code changes above merged to the current Cyton released firmware, you can download and flash this version of the firmware, by getting Julfy's (name is Bogdan R) repo yourself.
The issue states that 1000 Hz 16 channels works fine. You would have to test if you can go higher. There may be related issues with higher speeds in the SD card driver itself.

@wjcroft Thoughts? I would think this has been answered already in the last two years.

thank you @wjcroft. About the first part of my original question, do you know what the maximum speed is?
Thank you

Generally for EEG and EMG, 500 Hz is quite adequate. And many applications are also fine with 250 Hz.
@wjcroft Thank you.
