AC 3.2.1 ppm frames

Hello, tried to install qczek lrs ppm system on apm ArduCopter 3.2.1 and channels has no reaction, but apm ArduPlane 3.4.0 works fine. So question what is the difference between AC and AP ppm decoders, what is the required AC3.2.1 ppm sync time, low pulse, frame lenght…?

You will need to change to source code of arducopter 3.2.1, recompile it and upload it to APM board in order to get that feature running. You can take a look at the source code of Arduplane 3.4 to see how it is done.

Or you buy a new 30 US$ board ( http://ardupilot.org/copter/docs/common-autopilots.html ) and update to ArduCopter 3.6.9 and get it running out-of-the box.

Hello, thanks for your reply, please point me to ppm decoding source code of AC3.2.1 and AP3.4.0
