Ok, I made some progress in the IR controller department so I thought I'd share what I found.

I downloaded a program for Windows called IR Protocol Analyzer. This program works nicely. All you have to do is connect a photodiode to your sound card input (note polarity) and press the remote button. It captures all of the information, and if it's in the database, it identifies it for you.

In my case, the remote uses a standard NEC protocol. The NEC protocol allows for a device ID and then a command code to be sent. I was able to press each button on the remote and IR Protocol Analyzer decoded all of it for me.

The NEC protocol is very common, so I'm guessing someone has already done the work of programming the C code to decode the transmissions.

I attached a picture of the IR analyzer in action on my remote.

So far this is project really fun. This should make a cold winter go a little faster this year.
