  Troubleshooting power issues?
Posted by: Dpalm010 - 05-29-2021, 12:29 PM - Forum: Hardware - Replies (1)

Hi,

My lab purchased some pre-assembled pulse pals within the last couple years. The other day I noticed one was turning on and off by itself (not the triggers or inputs, but the screen/unit itself). I figured that it may have been an issue with the micro-USB connection since it seemed to do so with movement. I tried cleaning the micro-USB port with compressed air and now I can't seem to get it to boot at all. I've tried different cables and different power sources. I think we have another unit with a similar issue so it would be great to get to the bottom of this. 

Since I didn't build these and have only very recently started using them, I'm pretty unfamiliar with their design and troubleshooting. I've been reading the wiki and some posts on here but I'm wondering if anyone has some tips for fixing and/or troubleshooting this.

I am under the impression that the issue could be not the micro-USB port or power, but the screen itself. If this is the case I think I should still be able to detect and control the device with Arduino IDE & Pulse PalMatLab code. I couldn't seem to get either of these to work on one PC despite the device seemingly being identified as "COM1" in device manager. This specific PC is behind on some Windows updates that I think may be interfering with the Pulse Pal drivers so I may just need to try on another/updated PC.

Thanks for any advice!

Does this device control air flow as well as liquids? What are the output actions for the device? Which tubing connectors on the device do what?


  GUI Not Updating
Posted by: mjdubs25 - 05-14-2021, 04:18 PM - Forum: Software - Replies (1)

Hi Josh!

I have  a really weird issue where I can't use the GUI to change settings.  I can type in the GUI, but after the trial runs, it just changes back to what it was before(!?). To test this, I made a script that simply turns a light on for one second and I put that time in the GUI.  I can type in the GUI to change it, but no matter what I write, it just changes back to 1.  I am calling BpodParameterGUI('sync',S) on the first line of my for loop.  I'm using Bpod Console v1.63.  Is there any way you could help me with this?

Thanks,
Matt W.


  Change State with no Event Trigger
Posted by: MarcoC - 05-06-2021, 07:18 PM - Forum: Software - Replies (1)

Hello everybody,

I was wondering whether it was possible to implement a transition that does not happen immediately as a particular event occurs, but only when the timer elapses.


For instance, I would need a state where mice licks are required to occur to transition to a subsequent state (Reward) but that would happen only after the state timer is elapsed and not triggered by the mice' first licks.
If no licks takes place, Bpod skips the Reward states and finishes the trial.

Thank you in advance, 
Have a great day!
Marco


  Finding absolute time of trial/session start
Posted by: George - 04-13-2021, 04:30 AM - Forum: Software - Replies (2)

Ahoy, I'm trying to convert the timestamps coming out of Bpod from relative to absolute so I can align them with other processes.

I thought that `SessionData.Info.SessionStartTime` would store the time from which Bpod's clock begins, but it turns out this isn't the case. `SessionStartTime` is calculated by Matlab after the first trial is run.

It seems to me the best point at which to estimate when the trial began in Matlab is immediately before `RunStateMatrix` is called, but is there something more precise?

I'm also curious about when the state machine's clock starts running. Sometimes the first `TrialStartTimestamp` is a few or even several seconds (rather than 0 as I would expect). Is the state machine's 0-time tied to something specific that Matlab has access to?


  Noise in Analog Output Module Loop
Posted by: HK - 03-12-2021, 02:29 AM - Forum: Hardware - Replies (2)

Hi Josh,

I'm trying to use Analog Output Module to generate LED pulses with ramp-up and ramp-down intensity.  I can almost successfully control the LED shape, but when I check the output with oscilloscope, I realized that at the end of each loop, there is one sample that has 3-4V output.  I made sure that this sample is not included in my looped waveform.  Indeed, even if I generate a simple zero vector as a waveform and loop it, there are always one sample at the end of each loop that gives strange value. Do you have any idea why this happens?

I'm using WavePlayer, and my code for setting up WavePlayer is as follows (to make it simple, here I generated a simple zero vector waveform):

    LEDsamplerate = 10000;
    LEDwaveform = zeros(1,100);

    W = BpodWavePlayer('COM3');
    W.BpodEvents = {'On', 'Off', 'Off', 'Off'};
    W.TriggerMode = 'Toggle'; 
    W.LoopDuration = [20, 0, 0, 0];
    W.LoopMode = {'On','Off','Off','Off'};
    W.SamplingRate = LEDsamplerate;
    W.loadWaveform(1, LEDwaveform);
    LoadSerialMessages('WavePlayer1', {['P' 1 0]});


With this simple zero waveform, I still see a 5V sample at the end of each loop in my oscilloscope.  I would really appreciate it if you could let me know how I can resolve this issue.

Thanks,
Hiroyuki

  Installing the Analog Output
Posted by: SofB - 02-26-2021, 02:42 AM - Forum: Software - Replies (1)

Hi everyone, 

I am trying to install the Analog output and I've been following all the steps in this guide to upload the firmware
https://sites.google.com/site/bpoddocume.../teensy3_x
I make it all the way to the very last step, I press upload  (BpodWavePlayer), but then I am hit with an error message " 'SdFatSdioEx' does not name a type".
I've been trying to locate the 'SdFatSdioEx', but I cannot find it anywhere?
- What am I missing? Where is this 'SdFatSdioEx'? Do I need to install something additionally?

Thank you
Sof


  Connectivity issue after Arduino upload
Posted by: JasonGao - 02-12-2021, 11:00 PM - Forum: Hardware - Replies (2)

Hi, I was trying to upload a piece of code to an Arduino board. I did that through a serial connection that went through my Bpod, which in restrospect might not be the correct thing to do. The end result was that the blue indicator of the Bpod went off. I did all of the restarting and replugging I can think of but the blue indicator just won't come on again. The port still appears in PyBpod when I plugged the Bpod in but I can't run any code due to a connectivity error. Is there any way I can salvage my Bpod at this point? Thank you so much!
