  • 2.1.0 (2013-04-18): Improved existing examples and added two new examples for printing raw values.
  • 2.0.2 (2013-04-17): Made constructors initialize pointers to avoid possible problems.
  • 2.0.1 (2012-09-13): Added a 200 us delay after emitter state changes to ensure sensors do not start being sampled before the LEDs turn on/off.
