Code and CAD files for Matrix Dashboard

Raspberry PI initial set up

1. Run Raspberry Pi Imager for PI OS Lite

The following steps are not necessary. This can be done in the imager configuration settings

2. Add a blank ssh file in the root directory after install
3. Add a new file called wpa_supplicant.conf in the root folder with the contents below

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="NETWORK-NAME"
    psk="NETWORK-PASSWORD"
}

SSH into your PI

Installation instructions

(copy and paste the below until a requirements txt is made) sudo apt-get update && sudo apt-get install python3-dev python3-pillow -y

sudo apt-get install git
git clone https://github.com/jh442/matrix-dashboard.git
sudo apt-get install libopenjp2-7
sudo pip install python-dateutil
sudo pip install numpy
sudo apt install libopenblas-dev pkg-config libopenblas-dev
sudo apt install gfortran
sudo pip3 install scipy
sudo pip3 install pyowm
sudo pip3 install websocket_client
sudo pip3 install spotipy
sudo pip3 install garminconnect
sudo pip3 install rgbmatrix
sudo pip install -r requirements.txt

Create the config.ini file

This must be made in the root of the project for the credentials

1. cat > config.ini and paste your passwords.

If issues with scipy install, use sudo apt update sudo apt install -y python3-scipy

clone rgb matrix into dir

1. git clone https://github.com/hzeller/rpi-rgb-led-matrix.git to download the content into the folder
2. cd in rpi-rgp-led-matrix
3. sudo apt-get update && sudo apt-get install python3-dev python3-pillow -y
4. make build-python PYTHON=$(command -v python3)
5. sudo make install-python PYTHON=$(command -v python3)
6. Switch off on-board sound (dtparam=audio=off in /boot/config.txt)
7. reboot

Turn off the audio warning

There is a good chance you will get the following error

=== snd_bcm2835: found that the Pi sound module is loaded. ===
Don't use the built-in sound of the Pi together with this lib; it is known to be
incompatible and cause trouble and hangs (you can still use external USB sound adapters).

I found the best way to disable this was the following:

cd ../..
cd /etc/modprobe.d
sudo nano raspi-blacklist.conf
blacklist snd_bcm2835

exit and then sudo reboot

Once starting, the last step should be to navigate to the spotify section. It will ask for a URL. Click it, and then paste the entire URL from the web browser it opened in the SSH session terminal. This should authenticate the app

On a headless unit with Spotipy, it was needed to leverage the following code

self.auth_manager = spotipy.SpotifyOAuth( scope=scope, open_browser=False ) https://github.com/plamere/spotipy/blob/master/examples/headless.py

To run

1. CD into /matrix-dashboard/impl
2. sudo python3 controller_v3.py
