Led Matrix

Fred test:

[[Category:Ongoing_Projects]]

== Goal ==
The goal of this project is to display Nagios Server's status on RGB Led Matrix.

I have 4 Led Matrix, the idea is to create one box per matrix with 230V connector and Data IN/OUT
So we can decide if we want to use 1-4 Matrix

== Data flow ==
# Nagios server get servers status and store data into MySQL Database with XXXX plugin
# Perl script on Alix (PC Engine) is getting data from MySQL and transmit data by JSON to mbed (by USB).
# mbed get json's data from Alix and display to Led Matrix
# Led matrix display Servers status :-)

== Used componment ==
* 1 mbed NXP LPC1768 [http://mbed.org/handbook/mbed-Microcontroller]
* 2 RGB Led Matix (64x32) for display [[Led_Matrix_32x64]]
* 1 ALix 2d13 for getting Nagios status and sending to MBED [http://www.pcengines.ch/alix2d13.htm]

== Hardware pieces listing (per matrix box)==

== Perl script on ALIX ==
This perl script is getting data form MySQL to send to mbed.
It run every minutes by cron.

=== Requiert Perl modules ===

* blah

=== Source code ===
The source code is accessible from there

== JSON data example ==

== Special Thanks ==

Special thank to FIXME members who helped me with programmation and electronic stuff.
Specialy to :
* Simon for hadware design and mbed code improvement.
* Mathieu for discovering LED Matrix and explainition of how it work.
* Jean-Baptist,Raphael,Marc for there help with my newbies programmation questions.
* Florian for his help for leds PWM

== Project Owner ==
*Fred

== Todo List ==
* Make the perl script
* Make the box for LED matrix
* Make a PCB to connect Mbed
* Finish the Mbed code

== Issues ==
* The mbed code need to be optimized for memory issues

== Pictures ==
