Add GND as reference option for Neuropixels 2.0 #294

Open bparks13 opened 3 weeks ago

bparks13 commented 3 weeks ago

Currently the only reference options available for Neuropixels 2.0 probes are EXT, and TIP1-4. On commercial probes, GND is a valid option for references.

This would only be an option for non-beta probes. We need to go ensure that the correct bits are being turned on/off in the shank config for GND to properly be activated.

This will only be reflected at the GUI level by an additional entry in the drop-down menu, and all configuration will still be handled by the configuration methods in the base library.

@jsiegle In order to do this with 100% certainty, we either need the API source code that IMEC is using or we need a i2c trace of probe configuration when GND is selected as the reference. Can you help to provide either of these?
