Title: brainbay on ekg-emg shield
Post by: muxdemux on September 20, 2014, 02:58:19 AM
hi!

Has anyone successfully tried using brainbay on ekg-emg shield. Im having a hard time getting the correct signal.
Im using arduino uno r3 and I tried using other software and it worked well. Maybe it has something to do with the settings.

Just do an Insert Element>Source>Biosignal/EEG amplifier and Select OpenEEG P2 packetformat. It will show 6 channels. Just take the output from whatever jumper you have selected on the Olimex board.
For better performance, make sure you select the jumper on the Olimex board so that it supplies AVRef. (but if you do that, you will have to add the following line in the sketch, before starting the A/D :
analogReference(EXTERNAL);
and use shielded cable.
