Hi, I am new to bpod system. I know the port interface board (Product ID: 1008) is designed for the usage of phototransistor. I am wondering if it is possible to modify it so that it can detect lever press if properly connected to a lever switch? If so, how should I do it? I am not sure how the signal input port (circled in the attached pic) works either.
Thank you!

G'day Josh,

I've been using Bonsai to read the Rotary Encoder Module's USB output stream and there are two things I want to do.

1. Log position data on the module's SD card and retrieve it after Bonsai has released the COM
   
2. Probe whether there's a difference in the module's position and what Bonsai receives, since Bonsai's record of position information shows only integer degrees
   

Hi Josh,

I am currently building a second rig but I have encountered an issue with the rotary encoder module. I use the same Bpod version (v1.61), protocol code as well as hardware connections but for unknown reasons, the rotation data couldn't be logged/retrieved properly in the new rig. There aren't any errors when I run the task but the rotation data retrieved has a value of 0 for the "nPositions" field and the "Positions" and "Times" fields are empty. I have tried to use StreamUI() to launch the GUI and it can display the encoder position perfectly fine so I think this issue has something to do with the logging or retrieving. I have also tested the new module hardware itself (along with the new cables) by using it in my first rig and it can log and retrieve the data with no problem so the SD card is not broken or loosely attached. I have also tried to update the Bpod software to v1.64 but this issue didn't go away. 

Do you have any idea what could be causing this and do you have any solutions? Just FYI, both computers are using Windows 10 Enterprise, and the first rig has i7-4790 + 16 GB RAM whereas the second rig has i7-3770 + 24 GB RAM. 

Thank you,
Tin

Hey,
My aim is to track voltage changes from a pressure sensor via NI-DAQ and Bonsai so that Bonsai will trigger a state change in Bpod when the pressure stays constant for at least 1 second. 
I managed to connect Bonsai to Bpod via the socket connection (says "Bonsai status: connected") and found the OSC send message example in Bonsai gallery (which uses UDP instead of TCP, does it matter?), but I can't find what exactly should be written in the state machine code in Matlab. I know it has to do with soft codes but it seems like the documentation is outdated (e.g. in SoftCodeTriggeredStateChange example).
I did see the Bonsai example in the plugins folder in Bpod but it doesn't work for some reason (the camera capture just gets stuck when a light is shown and no message is generated in Bonsai), but anyhow it seems like none of the Matlab script files in the Bonsai folder I mentioned are the needed script to run this example.

Thank you,
Vik

Hi Josh and Bpod users!
I want to play different waveforms on different set of channels using Bpod's analog output, I do that with TriggerProfiles mode and it works fine. 
Now I want to trigger one profile, and then trigger another profile (on a different set of channels) without stopping the previous one. Is that possible? If not is there any other syntax that allows for simultaneous play of different waveforms on different channels? 

Thanks!

Hi, all

I have a question about the usage of Bpod & PulsePal.
I recently bought PulsePal and am trying to use it from the Bpod.

1, connecting issue
When I typed following code,

  P = PulsePalModule('COM5');

Following errors were backed.

  Error: ArCOMObject_Bpod/read (line 367)
  Error: The USB serial port did not return the requested number of bytes.

  Error: PulsePalModule (line 92)
              obj.nChannels = obj.Port.read(1, 'uint8');
  

I confirmed that the COM5 is actually the PulsePal port, and COM5 was recognized as " Arduino Duo",  however this error remains occurred.
A simple type of "PulsePal" works, and the return is as follows.

Quote:Searching for Pulse Pal. Please wait.
Connecting with PsychToolbox serial interface (low latency).
Trying port COM3
Pulse Pal connected on port COM3

Dear Josh,

When using BpodWavePlayer, we notice that when a wave is playing in loop mode (in one channel) and we try to update the waveform of another wave (to be played on a different channel) it starts producing distorted signals on all channels.

Here is a test protocol for this issue:

Hi Josh,

I have some problems with connecting bonsai to bpod. Bonsai was set to send '5' by softcode to bpod to trigger water once mouse reentered a specific area.
1) the number of 'softcode' is not stable after reopening Matlab and reconnecting bonsai. Sometimes, 'softcode1' event was detected in bpod while 'softcode6' event was detected in other times. Generally, how to receive any type of data (like float) in bpod besides integer? I found 'ReadOscByte.m' in bpod, but have no idea how to use it during running state machine.

2) Is it doable to run two Bpod (opening two Matlab programs) and bonsai programs at the same time and connect the two pairs using different ports? Will the 'softcode' data stream interfere with each other between different pairs of bonsai-bpod?

Hi,

I've used Bpod for handling a behavioral paradigm on a particular setup for a few months now.  I recently installed Matlab and Bpod on a new computer to handle another behavioral setup, but I ran into a persistent error whenever I tried to launch a protocol from the Bpod UI.

Hi Josh,

I have two issues. 
1. Is it possible to exit from the whole loop rather than the current loop? In my case, I'd like to terminate the session if mice did not have an action within a specific period (like 5        minutes). However, 'exit' only allows me to step out of the current loop.
2. Is it possible to measure the interval between two different events and then decide the next state according to the interval? In my case, I need mice to poke for at least 1s.              If they stayed in the poke for >=1s, they will get the reward. Otherwise, they need to poke again and the timer will recount from 0.

Thanks, advance,
Lei
