Are the nose pokes compatible with Bpod?

[maheump]

Hi,
I hope this finds you well! We were considering giving these nose pokes a try but the thing is that all our setups are Bpod-based. I haven't yet looked at the RJ45 connections you have designed for these nose pokes yet but perhaps you could very quickly tell us already whether your nose pokes would be compatible with Bpod and whether they would work the same way as the “port interface board” works in the Bpod environment?
Thanks for your help!

Hi Maxime,

The nosepoke is designed to connect to a pyControl system according to it's pinout, so unfortunately it won't be plug and play with BPod's pinout.

The circuit (schematic below) will output a 3.3V beambreak signal on pin1 and will need the following

• 5V on pin6
• GND on pin2
• ability to sink current on pin2 to control the overhead LED
• ability to sink current on pin7 to control the IR emitter.

To adapt it for BPod (assuming the linked pinout from the forum is correct/update?) I think you could tie the nosepoke's pin7 to ground (this will have the IR emitter always on) and then make the following connections:

Bpod -> nosepoke
GND pin5 -> pin2
5V pin4 -> pin6
Digital input pin1 -> pin1

Let me know if you have more questions, happy to help! Also, I have a new nosepoke that is a work in progress (https://karpova-lab.github.io/haptic-tof-nosepoke/latest/) that you may be interested in (although it too is designed for pyControl).

@maheump I also forgot to mention, you can gain access to the RJ45 pins by using a breakout board such as one of these or a pyControl port adaptor board
