Two of my customers have trouble setting up the Pixhawk - I myself have a Pixhawk, but don't use a Futaba receiver, thereby I can't replicate the problem (I would like to find out if the problem is connected to the receiver they use, or something else).
Both use a Futaba R7008SB receiver.
Both managed to upload the Firmware to their Pixhawks - but they are not able to do the radio calibration (the Pixhawk doesn't "see" the receivers, the bars in the calibration are all grey).
They have nothing else connected to the Pixhawk, except receiver (connected to the right port / RC), buzzer, safety switch and USB cable.
The Pixhawk signals via the big LED "pre-arm check failed" (which makes sense ;)
They power the Pixhawk via USB and at the same time with a LiPo (via the Power Module).
The receiver is "found" by the remote, the LEDs are on, the setting of receiver and remote (regarding the use of the SBUS) seems to be right. They use the right port of the receiver to connect to the Pixhawk.
I am happy about any suggestions ...
Thanks a lot in advance
When assigning Flight modes my three position Switch SE on my futaba radio is linked to flight modes 1,4, and 6. My other switches are not doing anything assuming they are already assinged to a port in my transmitter. How do I assign one of the other switches to operate the other 3 flight modes, 2,3, and 5. RC out puts are going to be tricky but Im not going to get into that yet. I assume the other switches on my transmitter I have could be assigned to the RC outputs once I have power to them?? Right now the other switches are assigned to Auxilary ports 9-14 on my transmitter but do not do anything in Mission planner.
To configure flight modes and switches see this
This allows you to configure a six position selection.
Thank you Martin I really appreciate it, a big help!
Thank you! I put a lot of thought into it. Here she is with the GPS mast we were talking about before.
Oh and lastly, if you use 5.8 tx anywhere on the machine, keep it well away from the gps- it causes big issues. Best to mount well away and pointing down.
Let me know how you go!
I have the same issue. Could you please elaborate how can I connect another supply to the output to resolve this issue. Will you be able to share a snapshot of your circuit?
thank you in advance
Most simple way to supply power to the servo rail is to use a bec from an esc or a separate bec supply module from any rc store. Just use a spare connection on your rail, red to pos and black to neg. I don't have any pictures but if you check out the setup guide at http://copter.ardupilot.com/wiki/common-powering-the-pixhawk/ (bottom of the page)
Hope this helps
