Need help in modifying OpenBCI_GUI adding piezo-buzzers control

Hello, World!

I'm new in the forum.
I have problems whith modifying  OpenBCI firmware and GUI.

The task is to generate PWM-signals to external piezo-buzzers from the free pins D11 and D12 of the Cyton board (need to generate it on pic-controller) and to modify standard GUI adding volume adjustment of PWM.

I did this on an external arduino board and on a separate program, now i need to do this on a regular board Cyton and a regular GUI-program. The work needs to be done quickly. I need reliable people for cooperation. Work is paid.

Details by e-mail.

    Ivan, hi.

    Have you seen some of these other threads? 


    There are advantages to this approach: (1) the Cyton on one serial port streams data to, (2) the GUI or other laptop program which does the signal processing and finally (3) the GUI or other laptop program outputs "command sequences" to a second serial port with another arduino that does your digital or motor control / robotics.

    Because the EEG signals are microvolt level, doing digital output of motor control / PWM / etc. directly on the Cyton -- has the potential to contaminate your microvolt input signals with crosstalk / inductive, capacitive coupling from your PWM cabling.

    A good example of this approach are Chip Audette's EEGHacker posts on his Hexbug or Shark remote controls.


    Regards, William
