Reverse engineered SAC9010QC/SAC12010QC IR protocol

Reverse engineered IR protocol for HomeFit Living / Alaska SAC9010QC/SAC12010QC remote control based on an NEC 756504012 IC.

If you want to go straight to the juicy parts, go checkout Docs/Protocol.md.

The Docs directory contains the reverse engineered protocol description, the SAC9010QC/SAC12010QC manual and other resources used. In the IRDumper directory you'll find a quick'n'dirty tool I used to dump the binary values the remote sends to the AC unit. I put this all in a spreadsheet and used that to 'decipher' the protocol. The Photos directory contains some photos of the remote control, it's PCB and my test setup. SignalDumps contains a few dumps of the IR signal as captured by my oscilloscope.

This is the actual remote:

It is apparently also known as the "Gree Y502 / Y512" remote.
