Receiver for Sony infrared remote and HID rudder pedals

irSony

Receiver for Sony infrared remote and HID rudder pedals on Arduino Leonardo.

Files and credist

• irSony.hs - Simple haskell script expected to run on a linux PC. It is receiving signals from a Sony IR remote and controling mplayer based on the received data. You probably do not need this or you want to modify it for your remote. Just cat /dev/ttyACM? to see what your remote sends.
• irSony.ino - Arduino sketch taking decoded data from IRSony and sending them to a serial line. It also handles rudder pedals and exposes them as a HID Joystick.
• IRSony.* - Implementation of Sony 12 IR protocol decoder It probably can be ported to other Sony protocols easily.
• PinChangeInterrupt*.* - PinChangeInterrupt from Andreas Rohner and NicoHood https://github.com/zeitgeist87/PinChangeInterruptHandler.git It did not seem to be packed as a proper Arduino library so I just copied the files. And I do not want to deal with the potential disapearance of PinChangedInterruptHandler repository anyway. It's simple enough.
• Joystick.* - Implementation of Joystick object for rudder pedals.

Notes

Sorry, but infrared decoder and rudder pedals features are merged in one sketch. I need it that way for me. Anyway, it is very easy to pull out the Sony infrared receiver from the code. Take all files named IRSony* and PinChangeInterrupt* and you are done. You can consult irSony.ino for example how to use IRSony decoder.

There is a pretty extensive debugging feature in the IRSony decoder. You can switch it on by defining symbol IRSonyTrace in IRSony.h file. You can print a precise timing of an infrared signal comming to the receiver. It can be used to analyze other IR protocols. Consult irSony.ino for a simple use case.

This was written because Ken Shirriff's IRremote library did not decode Sony protocol reliably and NicoHood's IRLremote library did not support Sony at all. And I was lazy trying to undertand / fix / extend those two libraries. That was the situation at the time of writing (April 2019).
