[Arnol Daniel Garcia Orozco]

Hi all,

I am try configured the Raspberry Pi Pico as Digital Outputs using PrawnDO, but I have the next error when adding the digital channel

and I am using this example as a reference.

Thank you for any help.

Arnol,

That repo you are referencing is the old development repository and is not up to date (we should probably archive it to make that clear). For docs, you should look to the main labscript-devices docs for usage.

As the traceback says, you need to connect DigitalOut to the `outputs` property of the PrawnDO (ie PrawnDO_0.outputs).

The change you need is 

DigitalOut(name='S1', parent_device = PrawnDO_0.outputs, connection = 'do0')

Hope that helps!

David,

I looked directly at the repository and completely forgot about the documentation, now it's working.

Thanks for the help!!!!
