Here’s a reverse engineering project that is instructive re: how to parse out several channels of IR commands issued to control an indoor helicopter.
From PetaVolt , via Hack A Day :
After seeing all of the Syma 107′s hacked I thought I would try to decode the IR protocol on my Propel ExecuHeli. Here are my findings.
For accuracy purposes I decided to find the signal on the controller board. I traced the IR LEDs through a transistor to pin 6 of the micro.
Unfortunately, there are no markings of any kind on the micro. It looks like it was manufactured without them.
Before digging into the protocol I thought I would have a look at what frequency the data is modulated at for the three different channels….
