  MED box output to Pulsepal Trigger
Posted by: neuralcircuit - 04-20-2019, 05:19 AM - Forum: Hardware - No Replies

Hi everyone,

I have a Pulsepal trigger channel hooked up to a MED behavior box output channel at 5 volts, and I found that the Pulsepal trigger responds only in the pulse-gated mode, but not the normal mode. Would anybody have any ideas to what kind of signal can cause this outcome?

Thank you!

I have recently started using Bpod (I installed software in Feb and started using hardware in March 2019).
I want to connect it with sound card but I am not sure which sound card will be good to use.
I have seen some people posting issues about installing it.
Which sound card do you recommend for me to buy?

  Retrieve subject name in data
Posted by: veronica - 03-20-2019, 11:37 AM - Forum: Software - Replies (2)


Is there somewhere in the session data where I can find the name of the subject that trained? I would like to load one of the files that is saved at the end of the session to matlab and then retrieve the name of the subject, can that be done?

Thank you!

  Poke detection jitter?
Posted by: trose_neuro - 03-12-2019, 03:54 PM - Forum: Hardware - Replies (2)

Dear Josh,

first of all: thanks a lot for your help so far. We now have a complete visual stimulation / 3d tracking system with BPod at its core that I am rather happy with.

One thing, though:

It seems as if the poke detection is rather jittery sometimes (not always...). We have a .7 state machine with custom-printed ports. Everything (incl. electric parts) is by-the-book. The problem is that sometimes port in & out events are triggered in rapid succession when the mouse enters a port. Finger-poking the ports then leads to jittery detection as well. All of our 8 ports are similarly affected. I bound ttl events to the port state changes and the changes seem to jitter around 10-100ms. In our script this triggers early withdrawal events en masse which is problematic. This seems to come and go, though, which makes me believe that this is an electrical issue. Also: the problem does not seem to be consistent - with pokes being detected just fine on some occasions.

I know that this is tricky to troubleshoot - but are there obvious steps I could follow to see what the problem is?


  Replacement part for 101-00581-59-1-ND SD Card Socket
Posted by: tommac - 02-19-2019, 05:25 AM - Forum: Hardware - Replies (2)

Hello everyone!

I'm looking for a replacement part for the 101-00581-59-1-ND SD Card Socket as it no longer seems to be available. The assembly instructions mention that most microSD card sockets require reflow soldering, but that this particular socket can be hacked by cutting the metal tabs to reveal the pins beneath. Are there any similar SD card sockets that can be used with this printed circuit board without reflow soldering (either with or without hacking the socket)?

Thank you for your help!


  Events for ports > 3 not registered on BPOD 0.7
Posted by: trose_neuro - 02-15-2019, 05:53 PM - Forum: Hardware - Replies (2)

Hi Josh,

after leaving my 3 port testing phase and upgrading my scripts and hardware to the full BPOD .7 8-port capacity, I had to realize that no Port events are registered for ports larger than 3.

I am running the latest Arduino sketch from the v22 branch of the repo (0_789). BPOD software is on latest master as well.

I can use the manual override to switch LEDs and valves connected to ports 4-8. However, as soon as I am running a protocol no poke events are detected on 4-8 - neither by override nor by actually poking. Same ports run without problems on lines 1-3. I tested this with my own scripts and also yours (e.g. the Light2AFC example, changing all Port keys to 4-6). Also without changing any of your code, manual override pokes are registered during running protocols in the Live Info panel for ports 1-3 but not 4-8.

Am I missing something?

Thanks for your help,

  String GUI parameter
Posted by: veronica - 02-15-2019, 02:52 PM - Forum: Software - No Replies


I am trying to set a GUI parameter to be a string that updates on each trial. I am able to see the string in the GUI if I initialize it on the default settings. But then I can't get it to update. Is it not possible? Do all parameters need to be numerical?

Thank you!

I don't even need to be able to modify it from the GUI. It could be a "read only" GUI parameter, if that were possible.

  No appropriate method, property, or field 'MOTORS' for class 'BpodObject'
Posted by: FloreB - 02-14-2019, 09:44 AM - Forum: Hardware - Replies (1)


I have the following error: " No appropriate method, property, or field 'MOTORS' for class 'BpodObject' " after calling BpodSystem.MOTORS

The system I am using is suppose to controle both the valves delivering the water to the mouse, and motors that control the platform on which the needles delivering the water are.
Motors are controlled by an additional arduino that is directly connected on the computer.  

The code used to work, and after some problems with the system I had to reset everything so I think I forgot to install something again but I am not sure and above all I don't find what... 

Do you have any idea of what the problem might be? 

Thank you for your help, 


  ttl channel outputs in State Machine r2
Posted by: Dani182 - 02-13-2019, 01:45 AM - Forum: Software - Replies (4)

To whom it may concern,

I am pretty new to Bpod (and Matlab) and looking for some advise as to how to drive different components using the State Machine r2. 

Up to now, we have been performing experiments using the previous version State Machine r1 and used the bare wires or ttl ports to directly drive the different components of the setup (e.g. stimulus apparatus, several speakers, triggers for scanimage software  and shatter). These were physically accessible from the bpod arduino board and could be directly coded into the state matrix. We have recently purchased the new Bpod machine r2 and I would like to know what's the best way to go in order to drive several components while having only 2 ttl input/output. Also how much coding would this require? it would be great to have a sample code just to have an idea. Thanks. Dani

  Replacement suggestion for BOM #17 TLP2160(TPF)CT-ND
Posted by: ondracej - 02-06-2019, 10:38 AM - Forum: Hardware - Replies (5)

Hi all, 

Does anyone have a good recommendation for an alternative supplier or an alternative part for the BOM #17 TLP2160(TPF)CT-ND - the 2-channel digital isolator?
I am running into major supply problems here in Germany. I would appreciate any ideas! This is the only problematic part I am missing. 

Cheers, Janie
