Rover and gimbal use

Posted by Raimo Noormaa on September 1, 2014 at 12:25pm

Hi,

I have successfully connected 2 servos to RC9 (tilt) and RC10 (roll, later will connect to RC11 aka pan), stabilization works.

I have a 7ch Spektrum DX7se and sat connected to Pixhawk. How can I map tilt(RC9) to Pitch(RC_MAP Pich, ch3) and roll (RC10) to Yaw (RC_MAP Yaw, ch4) stick. From the drop down menu I can select RC5 to RC8 but RC5 to RC7  have already been preserved for other functions.

Chould I be using from Full Parameter List RC9_FUNCTION and RC10_FUNCTION for configuring?

Regards,

Raimo

    Hi Raimo,

    How did you connect to the Pixhawk RC9 and RC10 channels when the Pixhawk only has eight primary servo outputs?

    Did you follow these Rover Wiki Pixhawk instructions for attaching a gimbal: Link

    There are six Aux servo outputs that can be used to control a gimbal and they have virtual channel numbers 50 (1) to 55 (6) Link

    Please carefully RTFM before proceeding any further to help prevent damage to your Pixhawk.

    Regard,

      Hi,

      Physical pins are aux 1 and aux 2, RC9 and RC10 I can select from the drop down menu in MP. I will go through the manual once more to see if I missed something. I can see the ch6 stuff but that's not what I'm looking for.

      • Power
        • Ideal diode controller with automatic failover
        • Servo rail high-power (7 V) and high-current ready
        • All peripheral outputs over-current protected, all inputs ESC protected

        Comprehensive power system with redundancy and extensive protection.

        • The Pixhawk is supplied with an in line power supply with voltage and current sensor outputs.
        • Ideal diode controller with redundant power supply inputs and automatic fail-over.
        • Servo rail high-power (max. 10V) and high-current (10A+) ready.

      And now what, Can I control gimbal with my left stick or it's just not possible? I can see that only signal and ground are connected and power should be on a separate wire with the PX4, what about the Pixhawk? Also I can see that the "+" and "-" rail is connected from pin aux1 to RC so why should I use separate wire for power?

      Regards,

      Hi,

      What I forgot to point out is that I have separate power supply connected to the servo rails. Servos and that sort of things get power from separate power supply (ESC BEC) and additionally I have the power module connected to the pos 6 on the picture from where the board, GPS etc gets its power from.

      Regards,

      Raimo
