Bpod port assembly interface example request

[MHRosenberg]

Hi there, my apologies if this is better posted elsewhere, but would it be possible for example code to be posted that would enable interacting with Sanworks Bpod port assemblies? These assemblies have a nose poke beam break, embedded LED, and solenoid for water delivery.

More generally, the documentation I'm seeing appears to be lacking full examples of entire experiments. Am I missing something?

Best,
Matthew

Hello Matthew -

Sorry for the delay. I really need to put up a 'project status' notice for Autopilot that we're recalibrating a bit before getting started again.

I don't have a specific example for the bpod nosepoke assemblies, but presuming the beam break logic is some sort of TTL-like signal, you should be able to wire up the logic pin directly to a GPIO pin on the raspi and use it with the Digital_In class.

I made our own nosepoke that is pretty straightforward to build, hand soldered with through-hole parts, and just uses the GPIO pins and onboard 5V rail for a solenoid: https://wiki.auto-pi-lot.com/index.php/Autopilot_Tripoke

examples here: https://docs.auto-pi-lot.com/en/latest/examples/index.html
and some of the experiments we did in our lab: https://wiki.auto-pi-lot.com/index.php/Wehrlab
https://github.com/auto-pi-lot/autopilot-plugin-wehrlab/

the design currently is to have some in-repo base Task class (eg Nafc ) and then extend those in plugins by inheriting from the metaclasses.

We're going to start work on Autopilot 2 sometime this fall :)

The main thing to watch out for are voltage levels. The bpod valve is a 12V solenoid. I think the IR led is 5V, but i'm not sure about the photodiode... i guess it is 3.3V since the teensy (which is the current platform is also 3.3V) - but the bpod control board has a bunch of hardware for level shifting, i think.
