1. Turn on SPI viasudo raspi-config

   Interfacing Options -> SPI

2. Install dependencies

   sudo apt updatesudo apt-get install python3-pip python3-numpy gitpip3 install RPi.GPIO spidev pillow

3. Install drivers for your display (you don't need to install both)

   1. If you have a Waveshare display

   git clone https://github.com/waveshare/e-Paper.git ~/e-Paperpip3 install ~/e-Paper/RaspberryPi_JetsonNano/python/

   2. If you have an Inky wHAT display

   pip3 install inky[rpi]

4. Download Zero BTC Screen

   git clone https://github.com/dr-mod/zero-btc-screen.git ~/zero-btc-screen

5. Run it

   python3 ~/zero-btc-screen/main.py

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 epd2in13v2and "picture" screens are select:

[base]console_logs             : false#logs_file               : /tmp/zero-btc-screen.logdummy_data               : falserefresh_interval_minutes :15# Price pair from Coinbase e.g. BTC-EUR or ADA-GBPcurrency                 : BTC-USD# Enabled screens or devicesscreens : [    epd2in13v2#    epd2in13v3#    epd2in13bv3#    epd2in7#    epd3in7    picture#    inkyWhatRBW  ]# Configuration per screen# This doesn't make any effect if screens are not enabled above[epd2in13v2]mode : candle[epd2in13v3]mode : candle[epd2in13bv3]mode : line[epd2in7]mode : candle[epd3in7]mode : candle[picture]filename : /home/pi/output.png[inkyWhatRBW]mode : candle

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 beforeexit 0

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

   conversely, you can run inscreen you can install it withsudo 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 yourenvironment

       [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
