• Raspberry Pi Model 3B+
• Speaker pHAT
• Adafruit PN532 RFID/NFC Shield (v1.3+)
• SparkFun FT231X Breakout

1. On Adafruit Adafrauit PN532 RFID/NFC Shield, make sure SEL0 is closed (solder bridge) and SEL1 is open. This will switch PN532 in UART mode.

2. Connect signals between Adafrauit PN532 RFID/NFC Shield and SparkFun FT231X Breakout in the following way:

   RFID/NFC Shield	FT231X Breakout
   5V	VCC
   GND	GND
   Analog in 4	RX
   Analog in 5	TX

1. Prepare Raspberry Pi with MicroSD card and Raspbian on it.

   Use balenaEtcher to flash the Raspbian image.

2. Put empty file ssh to the boot partition of the SD card to enable SSH access.

3. Insert the MicroSD card to Raspberry Pi and connect the power adapter.

4. SSH to your Raspberry Pi:

   ssh pi@<ip-address>
   

5. Change default password:

   passwd
   

6. Set correct locales:

   echo "en_US.UTF-8 UTF-8" | sudo tee /etc/locale.gen
   sudo locale-gen
   echo "LC_ALL=en_US.UTF-8" | sudo tee /etc/default/locale
   

7. Logout and SSH back to Raspberry Pi with the new password:

   logout
   ssh pi@<ip-address>
   

8. Set correct timezone:

   sudo dpkg-reconfigure tzdata
   

9. Change default hostname to cwgtk:

   sudo hostnamectl set-hostname cwgtk
   

10. Overwrite raspberry to cwgtk in /etc/hosts:

    sudo nano /etc/hosts
    

11. Reboot system and SSH back to Raspberry Pi:

    sudo reboot
    ssh pi@<ip-address>
    

12. Upgrade system packages:

    sudo apt update
    sudo apt upgrade
    

13. Reboot system and SSH back to Raspberry Pi:

    sudo reboot
    ssh pi@<ip-address>
    

14. Install common tools:

    sudo apt install git mc tmux vim
    

15. Select default editor /bin/nano:

    select-editor
    

1. Install NFC library:

   sudo apt install libnfc-dev libnfc5
   

2. Edit linbnfc.conf file:

   sudo nano /etc/nfc/libnfc.conf
   

3. Uncomment and edit the following lines:

   device.name = "pn532_uart"
   device.connstring = "pn532_uart:/dev/ttyUSB0"
   

4. Download cwgtk:

   git clone https://github.com/hubpav/cwgtk.git
   

5. Build tagcat:

   cd ~/cwgtk/tagcat
   make
   

6. Install support for Python 3 virtual environments:

   sudo apt install python3-venv
   

7. Install required Python 3 packages:

   cd ~/cwgtk/coffeelog
   python3 -m venv env
   source env/bin/activate
   pip3 install -r requirements.txt
   

8. Fix dependency issue with Python 3.7:

   pip3 install 'grpcio==1.23.0' --force-reinstall
   

9. Install /home/pi/cwgtk.json file with Google API credentials.

10. Install mpg123:

    sudo apt install mpg123
    

1. Edit coffeelog.service file:

   sudo nano /etc/systemd/system/coffeelog.service
   

2. Insert this content:

   [Unit]
   Description=CWGTK - Coffee Log Service
   After=network.target
   StartLimitIntervalSec=0
   
   [Service]
   Type=simple
   User=pi
   ExecStart=/home/pi/cwgtk/coffeelog/run.sh
   Restart=always
   RestartSec=1
   
   [Install]
   WantedBy=multi-user.target
   

3. Start and enable the service:

   sudo systemctl start coffeelog.service
   sudo systemctl enable coffeelog.service
   

Run this command:

curl -sS https://get.pimoroni.com/speakerphat | bash

Answer N when asked about full install:

Do you wish to perform a full install? [y/N] N

When asked about reboot, answer y:

Would you like to reboot now? [y/N] y

1. Edit alsa.conf file:

   sudo nano /usr/share/alsa/alsa.conf
   

2. Update these two parameters to index 1:

   defaults.ctl.card 1
   defaults.pcm.card 1
   

3. Create this configuration file:

   sudo nano /etc/asound.conf
   

4. Insert this content:

   pcm.!default  {
     type hw card 1
   }
   
   ctl.!default {
     type hw card 1
   }
   

The following procedure will configure phpLiteAdmin with the SQLite database.

1. Change default phpLiteAdmin password:

   nano /home/pi/cwgtk/phpliteadmin/phpliteadmin.config.php
   

2. Install required packages:

   sudo apt install lighttpd php-cgi php-cli php-mbstring php-sqlite3
   

3. Configure webserver:

   sudo lighty-enable-mod fastcgi
   sudo lighty-enable-mod fastcgi-php
   sudo service lighttpd force-reload
   

4. Create symlinks to phpLiteAdmin:

   cd /var/www/html
   sudo ln -s /home/pi/cwgtk/phpliteadmin/phpliteadmin.config.php
   sudo ln -s /home/pi/cwgtk/phpliteadmin/phpliteadmin.php index.php
