Cyton Digital Output

ahmed96alaa · February 2019

I wanted to ask why isn't there any documentation for the "DIGITAL OUPUT ON OPENBCI CYTON" , there's one already for the "8BIT BOARD"
Can i just use it as a reference to program the Kit's ATMega328P or it's considered as outdated ??

Ahmed, hi.

I think you are referring to this tutorial?

http://docs.openbci.com/Tutorials/07-Digital_Output_8bit_Example

A similar idea can be achieved with the current 32 bit Cyton, but the pins are different. Also, you would need to use some of the example code here as a basis,

https://github.com/OpenBCI/OpenBCI_32bit_Library

https://github.com/OpenBCI/OpenBCI_32bit_Library/tree/master/examples

As far as chipKIT / PIC32 pins, D13 would probably be a good choice,

http://docs.openbci.com/Hardware/02-Cyton

However also note this, that digital outputs connected to long wires, might inductively / capacitively couple into the EEG electrode leads and cause noise in the microvolt level input signals. So short wires and careful cable routing would be recommended.

Regards,

William
