device.analoginput not recognized

[ablot]

Hi all,

I have a brand new harp synchronizer but I don't seem to be able to get it to be recognised by the GUI.

The behaviour device (that I had previously) works fine. The synchronizer appers as Unknown device and when I try to connect the GUI it says that it's the wrong device type.

Is there maybe an easy way to flash the firmware on the device? Or another likely issue?

Hi,

1. Which GUI and version are you using to check the Harp Synchronizer?
2. What is the hardware version of the Harp Synchronizer you are using? (it's written on the printed circuit board of the device)
3. You are referring to the Synchronizer but your screenshot shows a Harp Analog Input board, is this correct?

Oh sorry I misread. "Synchronizer" means digital input board only and there is a separate repository for the analog input. Which has no GUI link so I gather it's only available through bonsai?

1. I tried to check with both the synchronizer and the behaviour GUI, which both showed the same thing but that might be normal for an analog device
2. I have an analog device 1.0
3. Indeed you are right it is an analog input board

I tried to find a GUI as my first attempt at a bonsai workflow did not seem to work. Here is a screenshot of the workflow:

It runs but the analoginput node never emits any output

and the test workflow that I found in the repo could not load with this error:

I did not install any driver or runtime specific for this device (as there was nothing described on the github page), I have those needed for the behaviour device and the synchroniser/digital input (not the clock synchroniser as I couldn't see any for this either but that's probably irrelevant here).

Correct, the Analog Input board does not have a dedicate GUI and it should not be recognized with the other standalone GUIs.

This being said, you can use Bonsai to work with this device. I would suggest you to use the most recent operators and give it a try. You can find information on the new operators here and how to install the device specific packages here.

You can find below a very simple example on how to display the acquired data of the analog input channels:

Hope it helps!

Perfect. That does work.

What I was missing:
1- The packages are not in community packages but only in nuget
2- The device needs to be started with a AcquisitionState message

Thanks!
