PPM Encoder - Update - ArduCopter User Group

Posted by Daniel Estes on July 14, 2013 at 9:15am

Should I update my APM with the newer PPM encoder before installing ver. 3.0.1 firmware? Note: I purchased Ardupilot Mega 2.5+ before March 1.

Thanks.

Hi All. How can I check which version I have? There´s no clear answer anywhere. Thanks a lot!

Does this new encoder allow failsafe with the Turnigy 9x stock package?

Another issue but unrelated to ver 3.0.1

Some RC transmitter/receivers (Futaba, Spektrum DX8) with more than 6 channels cannot be decoded reliably with the older PPM firmware. Has to do with overlapping PCM signals and interrupt handling. The new firmware corrects this. Symptoms with older firmware are random glitches on some channels. Best to upgrade if you are using more than 6 channels.

I was also wondering the same thing. I got my board last October.
