Disclaimer

Only supported on OSX.

Installation

0. Make sure you have Make & GCC (such as by installing Xcode or Command Line Tools For Xcode)

1. Run 'make'

2. Manually start the daemon by running build/blink1_monitor. Make sure that works (maybe watch a Youtube video and verify that it turns green).

Then, to install as a service that launches on startup:

3. Edit the file paulhodge.blink1_monitor.plist. You'll need to change this line:

   /Users/andy/blink1_monitor/build/blink1_monitor

to an absolute path pointing to the build/blink1_monitor file on your disk.

Copy the modified .plist file to your ~/Library/LaunchAgents directory.

4. Restart the computer, or just run these commands:

   launchctl load paulhodge.blink1_monitor.plist launchctl start paulhodge.blink1_monitor
