HISTORY:
  This driver is made as an example for using the Badge Bug to monitor a Cyphercon2016 badge over a serial port

USAGE:
  • Install Badge Bug
  • Flash this firmware to the Badge Bug (via Propeller Tool & Prop Plug, etc.)
  • Use a serial terminal emulator and a usb ttl serial cable to talk to Badge Bug at 115200 baud
  • Parse the incoming data to use the badge as a controller?
