JP1 Remotes

I'm on vacation and the house we're staying in has IR controlled A/C units, so of course, I had to capture the remote and build an upgrade for it.

Here's some details on the signals:

Frequency 38k
leadin pair: +8400 -4200
ONE pair: +550 -1650
ZERO pair: +550 -550
leadout pair: +550 1650
it's MSB format

It's a 28 bit signal:
8 fixed bits
16 variable bits (use varies by function)
4 bit checksum (add all the nibbles)

Here's a zip of all the files that I used to build the upgrade:
