WordClock

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 make in 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.
