Behavioral Syncing with TTLs

[chase_clark]

Hi there,

I was wondering if the DAQ board is capable of receiving and recording TTL signals from an external source (e.g. to signal when specific behaviours are occurring or cues are presented). It says on the wiki that the GPIO ports on the DAQ board are configurable however I'm uncertain of how to approach that. Has anybody attempted the to integrate TTL inputs with the DAQ board or come up with other creative solutions?

Thanks!
Chase

Hi Chase,
That feature hasn't been programmed into the DAQ yet but the hardware is capable of doing it. You would need to modify the firmware running on the DAQ and program in this feature. Multiple people have brought up this topic before but I don't know of anyone who actually went into the firmware to add it.

I am currently working on a new DAQ which will have this feature built into it but I imagine the new DAQ won't be ready for prime time till the end of this year at the earliest.

Hi Daniel,
I figured that was the case. Thanks for the heads up though!
