Automatically launch an FTC Live field timer display on a Raspberry Pi.

It may seem silly, but manually walking over and plugging in a keyboard/mouse to a Raspberry Pi in order to set up a field timer display is a hassle. We have better things to do during setup. So for the handful of people in the world that use a Raspberry Pi as their field timers for FIRST Tech Challenge competitions, here's a solution.

This repository comes with a few assumptions:

1. You use a Raspberry Pi as a field timer
2. You have a consistent IP address for your FTC Live scoring computer
3. You know ahead of time which field (1 or 2) the Pi will be on
4. Your Pi automatically logs in to a default user named pi

Given all of this, you can run setup.sh to get all of the files arranged correctly. (Change all mentions of the path /home/pi if your user is named differently.)

The setup script installs a program and two files:

1. xdotool, a program for emulating mouse clicks (to enable audio for the game sounds)
2. /home/pi/ftc-scoring-display.py, the script that does the actual work. Note: There are required changes in this file!
3. /home/pi/.config/autostart/ftc-scoring-display.desktop, the configuration that runs the script once the user logs in.

By their powers combined, Chromium will start automatically on login and show a field display for the currently-active event in FTC Live.

Be sure to change the SCORING_ADDRESS and FIELD_NUMBER constants at the top of the python script.

Happy hosting!
