Lanbahn-Spark

Lanbahn software for controlling model railroad accessory decoders with Spark.io cores

- see http://www.lanbahn.net/spark

Installation:

1) copy all files in a directory
2) install nodejs 
3) install the node modules "dateformat", "request" and "eventsource"
4) change settings (your access_token, your spark-server url) in sparkconfig.js
5) start program with: node lanbahn2spark.js

Pre-Requisites

1) lanbahn hardware with Spark Core (see http://www.lanbahn.net/spark )
2) Spark Core supplied with your wifi keys (with android SW on spark.io site)
3) "firmware_A121.bin" installed on Spark Core
4) adapt the config file lb2spark.json which defines the mappings between 
   Lanbahn commands and command for the sparks
and, if you want to have a fast response to commands:

a spark-server in your local network (see documentation on http://docs.spark.io/ )
and the keys of this server on your cores.

How it works

After starting the software with "node lanbahn2spark.js" a UDP multicast client is listening to UDP messages on the LANBAHN port 27027 and LANBAHN multicast group. When the client receives a "SET" messages with an address that can be matched to one of the connected spark cores, the spark core will be sent a http request with the appropriate command to change it outputs.
