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:

console_logs             : false
#logs_file               : /tmp/zero-btc-screen.log
dummy_data               : false
refresh_interval_minutes : 15
currency                 : BTC

# Enabled screens or devices
screens : [
#    epd2in13v3
#    epd2in13bv3
#    epd2in7
#    epd3in7
#    inkyWhatRBW

# Configuration per screen
# This doesn't make any effect if screens are not enabled above

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/ &
    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/'"
  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

       ExecStart=/usr/bin/python3 -u
    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
