# Implementation of xAAL in C
Here are some piece of code in C to implement xAAL devices.
Each folder contains a README.TXT and a Makefile.
So, feel free to read those files and type make.


## Quick start
1) Compile libxaal
2) Test demo
3) Enjoy!
4) Be indulgent regarding bugs...


## Details
- libxaal: An xAAL stack in C. The library is mandatory for following stuff.

- demo: Several dummy xAAL devices (lamp shutter thermometer dumper, etc.)
  Runnable on a text console on your PC, without the need of real devices.
  A good starting point for discovering the marvels of xAAL.

- baseservices: Special xAAL devices (cache, metadata DB, automaton).
  Optional, but useful on a real home-automation facility.

- xaaws: A generic user interface (using html websockets rest javascript)

- netprobe: Monitor the xAAL multicast bus, collect some statistics about
  bandwidth usage, etc.

- babbler: Text to speech for xAAL. Listen to the xAAL bus and tell
  notifications and events.  Funny but rapidly boring.  Also, a good example
  about using the metadata DB.

- xaal-stt: Speech to text for xAAL. Listen of sentences of the user (such
  as "Majordom, switch on the lamp of the kitchen."), try to guess what
  he/she wants, and sends xAAL commands.  Funny but also rapidly boring.
  Also, a good example about using the metadata DB.

- generic-sender: A simple generic xAAL device to ease integration with
  other systems (e.g.  video motion sensor, bluetooth proximity, etc).  The
  device listen for some data on a unix pipe and forwards it on the xAAL bus
  as notifications.

- generic-feedback-renderer: This device listen for "inform" xAAL request
  with a text, and render it to the user (e.g. by placing a call with a tts,
  by pushing a pop-up on a DLNA TV, etc.). More-or-less the counterpart of
  the generic-sender.

- sound-measure: An example of a sensor that does not stupidly forward
  measures continuously periodically.  Yes, one can do smarter things!

- tts: Text to speech for xAAL.  Wait for "say" requests and forwards the
  message to pico2wave+aplay

- xaafloor: Fall Detector using a SensFloor device.

- libxaal_aux: An auxiliary library with helpers to feed optional xAAL stuff.

- libxaal_jc: An auxiliary library with json2cbor and cbor2json transcoders.
  Note that transcoding rules are specific to the xAAL context.
