Rpi.GPIO library #14

Closed joearkay closed 5 years ago

joearkay commented 5 years ago

Hi all,

Very new to balena but extremely familar with Node Red. Once installed on a Pi 3, the logs show that the Pi GPIO library is not installed.

Alongside this I added the modbus node to my palette but this won’t install due to a dependency on serial libraries. Is there a way a I can include this in the docker container to be rolled out automatically for future deployments?

Thanks

I think that submitting a Pull request with a patch to correctly install the rpi.gpio library would be in the scope of this repo but the modbus addition would not be and you should fork it.

I have fixed the rpi.gpio dependency before so I can submit a PR as well if thats helpful.

@kanr if you could submit a PR that would be fab 👍 - I'll fork and do the modbus part. Thanks :)

@joearkay you can merge the above PR into your fork and should now be able to use the UART and I2C nodes in node-red. I am a pretty big fan of Node-Red + Balena and have done lots of experimenting so feel free to reach out if you want/need more help.

@kanr I’ve taken up your offer on reaching out on the forum! Hope that’s ok!
