rpi-rgb-led-matrix
This project uses a fork of the hzeller project on Github. The fork only has changes to specify the scrolling text as a command line argument. The main branch can be used once this pull request is accepted.
Use these commands to download the code to the Raspberry Pi and build the Web application's dependencies.
// install dependencies for the scrolling text sudo apt-get update sudo aptitude install libgraphicsmagick++-dev libwebp-dev sudo apt-get install libgraphicsmagick++-dev libwebp-dev -y sudo apt-get install libwebp-dev sudo apt-get install python2.7-dev python-pillow -y // download the C++ project that drives the GPIO git clone https://github.com/onebeartoe/rpi-rgb-led-matrix.git // build the project, specifing the Adafruit HAT as the hardware profile cd rpi-rgb-led-matrix sudo HARDWARE_DESC=adafruit-hat make install-python cd utils/ sudo make led-image-viewer cd ../examples-api-use make
Before continuing, be sure the following demo programs built into the rpi-rgb-led-matrix library run without errors and you see the LED panel lighting up.
The first demo is the spinning square.
$ cd rpi-rgb-led-matrix/examples-api-use $ sudo ./demo -D -m 0 --led-no-hardware-pulse --led-gpio-mapping=adafruit-hat
The second demo is scrolling test.
cd python/samples/ sudo ./runtext.py
Payara (runs WAR files)
The Web application for this project uses JEE and is packaged as a WAR file. Payara Server 4.1.x is used to run the Web app.
I tried Payara MicroProfile 164 from the main downlaods page, but it has issues running the WAR. The prerelease seems stable while running this project. See the following link and download JAR named "Payara-Micro (Web Profile Implementation)":
http://www.payara.fish/upstream_builds
Copy the JAR to the Raspberry Pi. It is used later in the project.
Here is a local copy of the Payara JAR, in case the specific version used in this project is not available for some reason.
The following command can be used to download the local copy of JAR file.
$ wget https://cdn-learn.adafruit.com/assets/assets/000/037/927/original/payara-micro-prerelease-2016-11-24.jar
