It was my pleasure to be an Indigogo supporter and beta tester of the new software solution for analyzing infrared signals using Arduino, Raspberry Pi and other controllers. It is a Windows application called AnalysIR. Software is now available for the general public here http://www.analysir.com/blog/
One of the nicest features of this system is that it allows you to use and IR learner chip to directly decode raw IR signals rather than using a decoder bandpass filter and AGC style chip that I normally recommend for my projects. This is essential if you do not know the base frequency of an unknown protocol.
The Arduino portion of their software is freely distributable at some point I will be adding something to my IRLib library for Arduino that will allow you to do frequency analysis. But no matter what I come up with it’s not going to be as useful as this full-featured package which is now available at a reasonable price considering the effort they’ve put into it.
I’ve had many requests for output of IR signals in different formats such as ProntoHEX that I’ve not yet been able to implement in my code. However this software easily outputs that format.
I highly recommend you check out the software.
