## Screen configuration



The application supports multiple types of e-ink screens, and an additional "picture" screen.



To configure which display(s) to use, configuration.cfg should be modified. In the following example an e-ink epd2in13v2

and "picture" screens are select:



```cfg

[base]

console_logs             : false

#logs_file               : /tmp/zero-btc-screen.log

dummy_data               : false

refresh_interval_minutes : 15

currency                 : BTC

### Autostart



To make it run on startup you can choose from 2 options:



1. Using the rc.local file

    1. `sudo nano /etc/rc.local`

    2. Add one the following before `exit 0`

   ```

   /usr/bin/python3 /home/pi/zero-btc-screen/main.py &

   ```

   conversely, you can run in `screen` you can install it with `sudo apt-get install screen`

   ```

   su - pi -c "/usr/bin/screen -dm sh -c '/usr/bin/python3 /home/pi/zero-btc-screen/main.py'"

   ```

2. Using the system's services daemon

    1. Create a new service configuration file

       ```

        sudo nano /etc/systemd/system/btc-screen.service

        ```

    2. Copy and paste the following into the service configuration file and change any settings to match your

       environment

       ```

        [Unit]

        Description=zero-btc-screen

        After=network.target

 

        [Service]

        ExecStart=/usr/bin/python3 -u main.py

        WorkingDirectory=/home/pi/zero-btc-screen

        StandardOutput=inherit

        StandardError=inherit

        Restart=always

        User=pi

 

        [Install]

        WantedBy=multi-user.target

        ```

    3. Enable the service so that it starts whenever the RPi is rebooted

       ```

        sudo systemctl enable btc-screen.service

       ```

    4. Start the service and enjoy!

       ```

        sudo systemctl start btc-screen.service

       ```



       If you need to troubleshoot you can use the logging configurations of this program (mentioned below).

       Alternatively, you can check to see if there is any output in the system service logging.

       ```

        sudo journalctl -f -u btc-screen.service

       ```
