Potential differences in data between stock OpenBCI firmware and Pushtheworld code #30

Closed echoGee closed 8 years ago

echoGee commented 8 years ago

I'm running Radio with https://github.com/pushtheworldllc/OpenBCI_Radios/releases/tag/v2.0.0-rc.2 and Firmware at https://github.com/pushtheworldllc/OpenBCI_32bit_Library/releases/tag/v2.0.0-rc.3 . But see that there is a difference in the noise floor and a particular ~31hz noise. The screenshot of the GUI in two different firmwares attached. I'm not sure if this is an issue. But would like to be tracked. Not that all the leads were floating and not connected to anything in both the cases.

Verified they are the same. That 31Hz signal is most likely environmental noise with a combination of floating terminals.
