"IRBetter" Project

As I indicated in the text, it took me two weeks to come up with the code that reads and processes the I/R receiver data from the remote control. The application presented here produces a CRC based on the incoming data, by checking at regular intervals. This application demonstrates how code can be greatly simplified by looking at a problem from another perspective.
