Adding Dig I/O channel to channel list.

Hello,

We are attempting to make use of the Dig I/O on the g.USBamp to add marks to the EEG for when a stimulus is applied. I've figured out the enable digital input option in config>source>DigitalInput and am able to see the "tick" marks in bottom trace of the EEG. I've attached a picture of what the current display of the channels is. However, right now the display is simply replacing the CP1 trace with the digital input. Is there anyway through the parameter configuration menu that another channel can be added to the display so that CP1 isn't lost?

Thank you.

Hi,

which version of the g.USBamp source module are you using? The current version uses state variables "DigitalInput1" ... "DigitalInput8" to store the 8 bits of the amp's digital input interface. For more information, see this wiki page:
