Copter: Assan Gunter 8Ch SBUS Receiver support #1120

Closed acanak closed 10 years ago

acanak commented 10 years ago

Assan Gunter 8 Channel Futaba Reciver is not working with 3.2-RC2. It is working fine with 3.1.5 on same hardware.

Attached images from px4io monitor as you can see, "it says this recevier does not allow safe frame detection" 3 1 5 3 2 master

The SBus support is definitely not (completely) broken - I continuously fly the master branch (including 3.2-RC2) using an SBus receiver. Both screenshots contain hints about major communication trouble between FMU and IO (io_reg_get errors, FMU_LOST flag, probably blinking amber B/E LEDs as well). Before troubleshooting SBus, you should try to solve this problem first, as all other information received form the IO might be completely junk under these circumstances.

The best way to do that is to flash an official (stable) firmware from http://firmware.diydrones.com. If the problem is not automatically resolved, try to power up the Pixhawk while holding the safety switch to enforce an update of the IO module. If there are still communication problems I would suggest to look for support here: http://ardupilot.com/forum/

@acanak,

Can you confirm the problem still persists with AC3.2-rc3 loaded through the mission planner's Beta Firmwares link?

rmackay9 commented 10 years ago

@acanak, from talking with the PX4 guys they say the warning is emitted if the inter-packet PPM spacing is close to a PPM frame length. It should output the measured frame lenght as well and ask if you could please run "px4io status" and copy the output here.

So response so closing.
