Tronberry

A daemon to fetch images from a Tronbyt server and display on a matrix LED display connected to a Raspberry Pi.

It has only been tested with a Raspberry Pi Zero 2W, but should work with all devices supported by https://github.com/hzeller/rpi-rgb-led-matrix.

Installation

In order to avoid flickering, follow these steps (taken from https://github.com/hzeller/rpi-rgb-led-matrix?tab=readme-ov-file#troubleshooting):

• Set dtparam=audio=off in /boot/firmware/config.txt
• Add isolcpus=3 at the end of /boot/firmware/cmdline.txt
• Run

cat <<EOF | sudo tee /etc/modprobe.d/blacklist-rgb-matrix.conf
blacklist snd_bcm2835
EOF
sudo update-initramfs -u

• Reboot

Now download either the latest binary release from https://github.com/tronbyt/tronberry/releases onto your Pi or build the Tronbyt client yourself on the device:

# Install dependencies
sudo apt-get update
sudo apt-get -y install git libwebp-dev libssl-dev zlib1g-dev

# Clone repository
git clone https://github.com/tronbyt/tronberry.git

# Build
cd tronberry
make

Running

# The Tronbyt URL looks like http(s)://…/next or ws(s)://…/ws
sudo ./tronberry ${TRONBYT_URL}

If you use tronberry with the original Tidbyt display, add the --led-panel-type=FM6126A flag. For a list of available options, run ./tronberry --help, there are many knobs to tweak.

To start tronberry at startup, create /etc/systemd/system/tronberry.service with the following content:

[Unit]
Description=Tronberry
After=network-online.target

[Service]
ExecStart=<ABSOLUTE_PATH_TO_TRONBERRY> <TRONBYT_URL>
Restart=always

[Install]
WantedBy=multi-user.target

Then run sudo systemctl enable tronberry to enable the new service.

To start it manually, run sudo systemctl start tronberry.
