CAMEL-8567 New camel-raspberry component (1st version)

[gautric]

I've started a new component to interface with an RaspberryPI.
I think it could be very interesting component to include it.

@davsclaus : Pi4j has got an 1.0-RC, I will check with author when he can provide an 1.1 final version

output endpoint with dynamic PIN rbpi://pin/{header.id}/mode?[options]

Are you referring to the header with key on the Camel message? If so see this FAQ
http://camel.apache.org/how-to-use-a-dynamic-uri-in-to.html

[davsclaus]

smarter URI style like rbpi://pin/1/mode?[options] have you got a documentation to implement it correctly

Can you explain a bit more?

If you want /mode to be part of the context-path, then you need to map that in the component class. eg that is the remaining parameter in the create endpoint. That requires a bit more coding, but some components do that.

For example some of the HTTP related
https://github.com/apache/camel/blob/master/components/camel-ahc/src/main/java/org/apache/camel/component/ahc/AhcComponent.java#L57

And the JMS component uses the context-path to know what kind of jms queue/topic you are using
https://github.com/apache/camel/blob/master/components/camel-jms/src/main/java/org/apache/camel/component/jms/JmsComponent.java#L485

Everything should work fine, I've included all comments
Just standby for pi4j 1.0 final version

Yay! This is great stuff. I'll take a look at it in the coming days.

Hi @gautric,

pi4j v1 is out. Can you include it in the project?

Also, can you create the documentation page for the component?

Cheers.

BTW I love your blog post [1]. It will be nice if you can update it as soon as Camel RPi is in master. I'd like to promote this link a little bit then. It is worth wider attention.

One more question - do have to install pi4j on the target device? Can't we just put pi4j jar into the the fat jar and then push it into the device? That would be easier from the deployment/demo point of view.

@gautric Hi Greg, any updates on this?

[davsclaus]

This component cannot be hosted at ASF. @gautric do you mind closing this ticket.
