This is an library for decoding infrared remote control commands encoded with the Philips RC5 protocol. It is based on the article "An Efficient Algorithm for Decoding RC5 Remote Control Signals" by Guy Carpenter, Oct 2001.
For more information see http://clearwater.com.au/code/rc5.
This library supports the extended RC5 protocol which uses the second stop bit S2 as an extension to the command value.

This library if a fork of the original RC5 library by @guyc - it is adapted for use with the c't-Bot ATmega framework and ported to C++14.
