piCorePhonie

I've been using the fantastic Phoniebox http://phoniebox.de/ for a couple of years, but Spotify just stopped working: MiczFlor/RPi-Jukebox-RFID#1815

I have an LMS SqueezeboxServer server anyway that supports Spotify well, so I installed piCorePlayer https://www.picoreplayer.org/ to use my Phoniebox as an LMS SqueezeboxServer client and wrote a script based on https://github.com/baztian/rfid-squeezectl to use RFID tags for starting Spotify playlists. This is not supposed to be a replacement for Phoniebox, just a quick and dirty fix to get Spotify working again quickly.

See instructions below to set up a Phoniebox with control buttons, rotary encoder, rc522 RFID reader, status LEDs and an OnOff shim. Of course, there is no GUI and also an automatic shutdown when idling is missing.

Installation

Download picoreplayer https://docs.picoreplayer.org/downloads/ and follow instructions https://docs.picoreplayer.org/getting-started/ . Call player piCorePhonie

Set up Wifi without Ethernet

Before inserting the SD card, add file wpa_supplicant.conf to boot partition:

# Maintained by piCorePlayer
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=staff
# Two Character Country Code
country=US
update_config=1

network={
    ssid="yourssid"
    psk="password"
    key_mgmt=WPA-PSK
    auth_alg=OPEN
}

PCP Extensions:

Using the "main page" of the web GUI, resize the file system so that it uses the whole SD card ("resize FS"). Then, install these PCP extensions:

• python3.8-dev
• python3.8-pip
• python3.8-wheel
• python3.8-setuptools
• git
• gcc
• glibc_base_dev
• linux-5.10.y_api_headers
• pcp-sbpd
• pcp-mpg123

backup python directory

Important, do a backup using the pcioreplayer GUI before each reboot, otherwise changes are deleted!

Make sure python directories are included in the backup. SSH to raspberry (https://docs.picoreplayer.org/how-to/access_pcp_via_ssh/) and run

nano /opt/.filetool.list

to add

usr/local/lib/python3.8/site-packages/

RC522 rfid reader

Install python libraries sudo pip install squeezebox-controller pyyaml spidev RPi.GPIO

The pi-rc522 version on pypi didn't work for me, so take the github repo:

cd /tmp
git clone https://github.com/ondryaso/pi-rc522.git
cd pi-rc522/
sudo pip install .

Clone this repository

git clone https://github.com/maahn/piCorePhonie

Create the config file /home/tc/piCorePhonie/rfid_config.yaml. Mine looks like

host: 192.168.0.243
port: 9000
player: Piloubox2
startsound: /home/tc/176674950.mp3
timeout: 600
80-243-128-154-185: "Spotify: weiss"
115-232-255-127-27:  "Spotify: gelb"
96-89-35-45-55: "Spotify: blau"
134-20-108-241-15: "Spotify: grun"
54-1-102-241-160: "Spotify: orange"

host port, and player name could be probably figured out automatically... startsound is an mp3 file that is played when the player is ready. If the key startsound is missing in the YAML file, no sound is played. timeout is the idle time in seconds after which the player turns off (see below). The numbers are the ids of the RFID cards and the corresponding LMS playlists. To get the RFID ids, ssh to the raspberry, hold an RFID tag to the reader, and run

python3 showRFID.py

Using the web GUI, got to tweaks, and add the following to the picoreplayer User commands (under tweaks) to start the RFID script after booting

/home/tc/piCorePhonie/readRFID.py /home/tc/piCorePhonie/rfid_config.yaml > /home/tc/readRFID.out 2> /home/tc/readRFID.err

Shutdown script

To turn the player off after some time when idle, add the following to the User commands:

/home/tc/piCorePhonie/idleShutdown.py /home/tc/piCorePhonie/rfid_config.yaml > /home/tc/idleShutdown.out 2> /home/tc/idleShutdown.err

The diel timeout is specified in the yaml file with the timeout key.

GPIO Buttons

sbpd is used for the GPIO buttons, see https://github.com/coolio107/SqueezeButtonPi-Daemon for details. See button.sh in the repository and modify th elast line. Make sure to check out https://abyz.me.uk/rpi/pigpio/faq.html#Sound_isnt_working for the t option of pigpiod and the script to the picoreplayer User commands under tweaks

/home/tc/piCorePhonie/button.sh

OnOff Shim

https://forums.slimdevices.com/showthread.php?109734-piCorePlayer-Pimoroni-OnOff-Shim

go to 'Tweaks' page of the PiCorePlayer GUI, under 'Poweroff/Shutdown Overlays'

• set gpio poweroff to 'yes' , '4', 'Active Low'
• set gpio shutdown to 'yes', '17', 'Active Low'
• click on 'Install Monitor'

Status LED

To add external status LEDs, follow https://docs.picoreplayer.org/how-to/edit_config_txt/ to edit config.txt

dtoverlay=gpio-led,gpio=12,trigger=heartbeat,label=statusled0
dtoverlay=gpio-led0,gpio=16,trigger=cpu,label=statusled1

Store everything

Using the web GUI, don’t forget to do a backup, otherwise all changes are gone after a reboot
