Executing arbitrary code through the RuneUI

[anslab]

Hi all,

I'm running RuneAudio on a Raspberry Pi B+ and I'm really happy with it. However, there is one thing that I'd like to do to make the experience even better.
I'm pluggin the raspi into a Denon Hi-Fi system, and I want to integrate the raspi with Denon's system connector interface (i.e. using the Denon controller to change track on RuneAudio, and wake up the system when RuneAudio issues command.

I found this guy : http://kfigiela.github.io/2014/06/15/de ... connector/ who essentially did the most part (retroengineering of the connector protocol, etc.). What I would like to do now is to integrate his work with RuneUI.

How can I do that (executing arbitrary code when the user does something in the UI, and making the underlying media player listening to events that don't come from the web UI)?

Hi anslab,
could you bring a practical example of what you would like to implement?

Your control daemon should be bidirectional, allowing your remote and MPD (or the whole RuneAudio, if you want to include also other system events) to talk together.
The daemon should monitor MPD's state file to detect its changes, and consequently read and interpret MPD's response to send the correct command to the serial port.
RuneUI works in the same way, you can find most of the relative code in this file:

Thanks ACX, this is exactly the information I need. For now, I think I will start with only controlling MPD, however, if you think it's worth it, I can do something modular enough so it can be easily re-usable by people with different needs/hi-fi systems.

Thumbs up for modularity and reusability. The ideal approach from my point of view would be a standalone and lightweight daemon integrated as a toggleable and configurable option in the UI under the Settings page. Don't worry about the integration with the UI, we'll take care of that.
