mate-matrix

Mate Matrix is a LED display made with bottles of Club Mate.

It's based on Fadecandy and Open Pixel Control.

How to use

Clone this repo with submodules to import fadecandy:

git clone --recursive [email protected]:LgHS/mate-matrix.git

Run fadecandy with a pre-existing config:

./fadecandy/bin/fc-server-rpi config/fc-config-[myconfig].json

Note: server is also available for Win7+ and OSX+. See fadecandy/bin for README.

Generate config

With one main config file you can generate config files for :

• Fadecandy server
• Processing client
• Open Pixel Control OpenGL simulator.

To keep things tidy, put main config in project root and generated configs in config/ folder with prefixes (fc- for fadecandy and opc- for OPC simulator).

Processing config should go inside each sketch data folder.

Fadecandy

node generator/fadecandy.js my-config.json > config/fc-myconfig.json

OPC Simulator

Use with Open Pixel Control OpenGL viewer (Linux or OSX only).

To build and run simulator, see README in OPC repo

To generate config for simulator:

node generator/opc-simulator.js my-config.json > config/opc-myconfig.json

Note: looks like it doesn't work on Linux anymore :( More info here

Processing

Generate config file used by MateMatrix.pde.

node generator/processing.js ./my-config.json > src/processing/MyProjectSketch/data/matrix_config.json

Config reference
