Type mismatches when reading files per register

[mgraupe]

Hello,

I am running a Harp device and I log to separate files per register following : https://harp-tech.org/articles/logging.html

However, when I try to read the files, I get ValueErrors for several registers complaining about wrong data type. For example :
data = device.AnalogData.read('Harp/Behavior_Output_33.bin')
aborts with
ValueError: expected payload type int16 but got uint8.

It's the same behavior for the DO* registers. Other registers such as for example DI0Trigger can be read.

Thank you for your help in advance.

Best,
Michael

@mgraupe can you confirm what version of firmware you are running on the behavior board? There was a change in the structure of analog registers in recent firmware.

[mgraupe]

Here are the specs of the board and the python package :
DeviceName: Behavior
FirmwareVersion 3.2
CoreVersion 1.13
HardwareVersion 2.0

harp-python version 0.4.0

Thanks,
Michael

data = device.AnalogData.read('Harp/Behavior_Output_33.bin')

The register 33 of the Behavior board is NOT AnalogRead. It is actually a reserved register (https://github.com/harp-tech/device.behavior/blob/ddf71cfbec248f1cd7b7abaa9c477ac58e4a4dae/device.yml#L15).

If you want to open the analog data, you should pass the register with address 44.

That worked thanks. I got distracted by a wrong device.yml file.

I have two follow up questions :

1. we have implemented the quadrature encoder example but there is no encoder ouptut (neither from the encoder Bonsai node, nor in the analog data output file). Does the encoder have to be activated?

2. Where can I find a map of all the ports of the Harp.Behavior device? What is individual connector identify in Port0, 1 and 2?

Thanks,
Michael

1. Can you clarify? By no data do you mean that you don't get any events from address 44 (AnalogInput, that packs the data from the encoder too) or that the data is all 0s? If you get no events, you may have to manually turn on events via the register EventEnable (https://github.com/harp-tech/device.behavior/blob/ddf71cfbec248f1cd7b7abaa9c477ac58e4a4dae/device.yml#L246)

2. Not sure I follow. Port0 is Port0 in the PCB silk (or P0 when it is abbreviated)

1. I mean all encoder data is 0's. I get digital input events (data = device.DigitalInputState.read('Harp/Behavior_Output_34.bin') shows transitions of all three di lines). Does that mean EventEnable is activated? How to turn on events via the register?

2. I was searching for a while to get the pin identify within port0, port1 and port 2. Fount it finally here : https://github.com/harp-tech/device.behavior/blob/main/Hardware/PCB/harp%20behavior.pdf

Thanks.

1. Can you share how you are wiring the encoder as well as the workflow you are using to configure?

[mgraupe]

I follow in detail the example shown here: https://fchampalimaud.github.io/cf.bonsai/workflows/HarpExamples/BehaviorBoard/QuadratureEncoder/QuadratureEncoder.html
i.e., I implemented the same workflow and the same wiring.

[bruno-f-cruz]

Uhm the workflow seems correct. So that probably indicates a problem with wiring. Can you share the pinout you are using?

[mgraupe]

It turns out that I didn't copy the workflow from the Champalimaud website but recreated it by hand (didn't realized that there is a copy function of the workflow). I realized that the enable rotary encoder was not set in the Misc of the CreateMessage node Behavior.EnableEncodersPayload.

It's working now. Thanks for bearing with me.

Cheers,
Michael
