Hi,
I use ULRS http://www.itluxembourg.lu/site/ultimate-lrs-2-0-beta/ as my receiver.
Before librepilot, I used openpilot with my CC3D and it work fine. Now I use librepilot and it can't get the ULRS PPM signal.
I ask the author of ULRS, he said that PPM frame pulse of librepilot is too short. With ULRS it's 3 ms.
I'm not sure that, could you please check that?
thanks.

Hi, welcome.

Double check which input you set in Hardware tab and select the right pin in receiver port according to Oneshot or not.

Take a look here:
