It's a clock...with words.
- Solder the shield together
- Connect the shield to the Pi
- Connect a 5V, 4A power brick to the shield.
- Connect the Pi to Ethernet (This assumes the Pi is Running Raspbian Jessie)
- Log in via SSH
- Setup Timezone by running
sudo raspi-config - Configure RTC:
https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=125003 - Get the right python libraries: https://learn.adafruit.com/adafruit-rgb-matrix-plus-real-time-clock-hat-for-raspberry-pi/driving-matrices
- Clone this repo on the PI (or at least the software directory) and navigate into it
- Run
sudo makein the "matrix" directory - Python will bind to the rgbmatrix.so file that is generated. - Make WordClock.py executable: chmod +x WordClock.py
- Add this to crontab (
crontab -e):@reboot sudo /home/pi/WordClock.py > /dev/null 2>&1 - Reboot
- The ethernet is no longer needed, but you can connect it briefly to auto-update the time if the RTC drifts.
