Installation Guide

This guide will help you set up the SimplicityPlayer on your Raspberry Pi. The installation process is divided into several steps, each of which is detailed below.

Prerequisites

Before you start, make sure you have the following components ready:

  • Raspberry Pi 3A+ (other models may work, but the software was tested on this model)
  • InnoMaker HiFi DAC HAT (RPI-HIFI-DAC-PCM5122)
  • RFID Reader (RC522)
  • LCD1602 + LCD I2C Interface (PCF8574)
  • Cherry MX Button with a 4k7 Ohm Resistor

Step 1: Prepare the Raspberry Pi

  1. Install Raspberry Pi OS Lite on your Raspberry Pi. You can find the official installation guide here.
  2. Set up your Raspberry Pi, connect it to the network and connect to it via SSH.
  3. Update the system by running the following commands: 
    sudo apt update
sudo apt upgrade
  4. Enable the I2C & SPI interface by running: 
    sudo raspi-config
    • Select 3 Interfacing Options.
    • Select I3 SPI.
    • Would you like the SPI interface to be enabled? -> Yes
    • The SPI interface is now enabled.
    • Select 3 Interfacing Options.
    • Select I4 I2C.
    • Would you like the ARM I2C interface to be enabled? -> Yes
    • The ARM I2C interface is now enabled.
    • Select Finish.

Step 2: Set up the Audio Output

  1. Connect the InnoMaker HiFi DAC HAT to your Raspberry Pi (only when the Raspberry Pi is powered off!)
  2. Edit the /boot/firmware/config.txt file by running: 
    sudo nano /boot/firmware/config.txt
  3. Add the following lines to the end of the file: 
    dtoverlay=allo-boss-dac-pcm512x-audio
  4. Save the file by pressing Ctrl + X, then Y, and finally Enter.
  5. Reboot your Raspberry Pi by running: 
    sudo reboot

Step 3: Set the default audio output

  1. Check the audio output devices by running: 
    aplay -l
  2. Find the device that corresponds to the InnoMaker HiFi DAC HAT. It should look similar to this: 
    card 2: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm512x-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
  3. Edit the /etc/asound.conf file by running: 
    sudo nano /etc/asound.conf
  4. Insert the following lines to the file: 
    pcm.!default {
    type hw
    card 2
}
ctl.!default {
    type hw
    card 2
}
    change the card 2 to the card number you found in step 2.
  5. Save the file by pressing Ctrl + X, then Y, and finally Enter.
  6. Reboot your Raspberry Pi by running: 
    sudo reboot
  7. Test the audio output by running: 
    speaker-test -c2 -t wav
    You should hear a voice saying "Front Left" and "Front Right" from your speakers.

Step 4: Install and configure MPD

  1. Install MPD by running: 
    sudo apt install alsa-utils mpd
  2. Edit the /etc/mpd.conf file by running: 
    sudo nano /etc/mpd.conf
  3. Add the following lines to the end of the file: 
    audio_output {
    type "alsa"
    name "RPI-HIFI-DAC-PCM5122"
    device "hw:2,0"
    mixer_control   "Analogue"
}
    change the device "hw:2,0" to the device number you found in step 2.
  4. Save the file by pressing Ctrl + X, then Y, and finally Enter.
  5. Restart MPD by running: 
    sudo systemctl restart mpd

Step 5: Install automount for USB drives

  1. Install the required packages by running: 
    sudo apt install udevil
  2. Create a new file by running: 
    sudo nano /etc/systemd/system/devmon.servic
  3. Insert the following lines to the file: 
    [Unit]
Description=Automount USB drives
After=network.target
 
[Service]
Type=simple
User=pi
Restart=on-abort
ExecStart=/usr/bin/devmon
 
[Install]
WantedBy=multi-user.target
  4. Save the file by pressing Ctrl + X, then Y, and finally Enter.
  5. Enable and start the service by running: 
    sudo systemctl enable devmon
sudo systemctl start devmon

Step 6: Install the SimplicityPlayer

  1. Install the required packages by running: 
    sudo apt install python3-virtualenv git
  2. Clone the repository by running: 
    cd ~
git clone https://github.com/meteyou/SimplicityPlayer.git
  3. Create a new virtual environment by running: 
    cd ~
virtualenv -p python3 ./SimplicityPlayer-env
./SimplicityPlayer-env/bin/pip install -r ./SimplicityPlayer/requirements.txt
  4. Copy config.cfg.example to config.cfg by running: 
    cp ~/SimplicityPlayer/config.cfg.example ~/SimplicityPlayer/config.cfg
  5. Copy the systemd service file by running: 
    sudo cp ~/SimplicityPlayer/SimplicityPlayer.service /etc/systemd/system/
  6. Enable and start the service by running: 
    sudo systemctl enable SimplicityPlayer
sudo systemctl start SimplicityPlayer
