Go-based software to control a raspberry pi LED matrix.
This is a Go project for displaying various types of "Boards" on a Raspberry Pi controlled RGB Matrix. The ideas here were heavily inspired by https://github.com/riffnshred/nhl-led-scoreboard . It uses some CGO bindings for the RGB matrix library https://github.com/hzeller/rpi-rgb-led-matrix. I chose to create my own project based off of those existing ideas because I wanted to be able to easily extend support for additional sports (see Roadmap section). I chose to write this in Go because I prefer it over Python, and theoretically it will run more efficiently than a Python-based one.
I run this on a Pi zero and a Pi 4. If you want to use the "Web Board" feature (see Web UI), I recommend at least a Pi 3.

This project currently supports all Raspberry Pi's with an armv7l or aarch64 architecture. This includes Pi 3b, 4, Zero 2. Pi's with the armv6 architecture are no longer supported, but those can run version v0.0.83 and older- this would include the original Pi Zero.
You can check your Pi's architecture by running the following command:
uname -mThere's a helper install script that pulls the latest release's .deb package and installs it and starts the service. Obviously, piping a
remote script to sudo bash is risky, so please take a look at script/install.sh to verify nothing nefarious is going on. You can always manually download the .deb package in the Releases Section. Just make sure to pick the correct one for your architecture.
Run the following command in a Terminal on your Pi
curl https://raw.githubusercontent.com/robbydyer/sports/master/script/install.sh | sudo bashTo try out the latest beta release, run the following on your Pi:
curl https://raw.githubusercontent.com/robbydyer/sports/master/script/beta-install.sh | sudo bashIf you wish to install from source (either you don't trust the released .deb or you have a non-supported Pi), you can compile the binary on your own Pi. There are two options:
You can just compile the binary, skipping the systemctl configuration. Clone the repo to your Pi, then run the build script. This will result in a file named sportsmatrix.bin
script/build.localYou can build your own copy of the DEB package- these are what are distributed with official releases and are what
script/install.sh and script/beta-install.sh install. You must set a VERSION env var, but it can be anything you want.
VERSION=1.0.0 script/deb-build.shYou can run the app without passing any configuration, it will just use some sane defaults. Currently it only defaults to showing the NHL board. Each board that is enabled will be rotated through. The default location for the config file is /etc/sportsmatrix.conf
See the Full Example Configuration
For a list of all possible team abbreviations (including conference/divisions when available), see this list
If you installed the app with the installer script or a .deb package directly, then the service will run automatically. You can start/stop/restart the service with systemctl commands:
# stops the service
sudo systemctl stop sportsmatrix
# Restarts the service, like after changes to the config file
sudo systemctl restart sportsmatrixYou can also run the app manually in the foreground. The .deb package installs the binary to /usr/local/bin/sportsmatrix
NOTE: You MUST run the app via sudo. The underlying C library requires it. It does switch to a less-privileged user after the matrix is initialized.
# Show all CLI options
sportsmatrix --help
# Run with defaults
sudo sportsmatrix.bin run
# With config file
sudo sportsmatrix.bin run -c myconfig.conf
# NHL demo mode
sudo sportsmatrix.bin nhltestThere is a (very) basic web UI frontend for managing the board. It is bundled with the binary and served as a single-page app. The UI gives buttons for all the backend API Endpoints. You can also view a rendered version of the board in the "Board" section (make sure your configuration enables this). Front-end dev is not my strongsuit, so it's not particularly pretty.
The Web UI is accessible at http://[HOSTNAME OR IP]:[PORT], where port is whatever you configure the httpListenPort in your config file to be. For example, if your Pi's hostname is mypi and your configured listen port is 8080, http://mypi:8080
Example of the Web Board:
The Web UI has a built-in doc page describing the API. It also includes an interactive way to test API calls. There's a
button in the nav "API Docs", or you can go to http://[YOURIP]/docs
If you would like to configure certain image directories to contain "jump only" images (only seen when an API call is made to show them), you can do so by configuring them like:
imageConfig:
directoryList:
- directory: /my/image/dir
jumpOnly: true
Then, to display a particular image in that directory, make the API call and pass the desired image name.
curl -X POST --header "Content-Type: application/json" -d '{"name":"goal.gif"}' "http://myhost:myport/imageboard.v1.ImageBoard/Jump"
I'm always open to pull requests for features/bug fixes! Feel free to open an issue if (when) you find a bug.
For easy/faster testing without compiling on a Pi, you can use the ConsoleMatrix type for generating the board layout in the terminal.
$ script/shell.console

It sort of works, but with some weird caveats: running the cross-compiled binary on the Pi is resulting in brighter/washed out images for me. If anyone can figure out how to make this work better, please let me know.
# Building directly on a Pi. Creates a binary named "sportsmatrix.bin"
script/build.local
# To build an armv6l image (for a Pi zero) in docker:
# This results in a binary named "sportsmatrix.armv6l"
script/build.armv6l
# To build arm7 image (Pi 4?). Results in a binary
# named "sportsmatrix.arm7"
script/build.arm7Any new boards just need to implement the board.Board interface. A new sports type board would be best to implement the API, Team, and Game interfaces in a sportboard.SportBoard (See the NHL Board for an example).
