@Jetson-Nano Are you using QGC to map joystick buttons to functions? What version of PX4 are you running on your FC v2?
@Eric-Katzfey yes , I am using the QGC to map joystick buttons. I am using the voxl-fpv-dev version from the modalai px4 repo. I am using the FPV 4-in-1 ESC. I am not able to get more than 2 toggle switches and also not able to assign them two way.

@Jetson-Nano
voxl-fpv-devis the name of the branch. The version will be a number, such as1.14.0-8.104.3. Most of the joystick button mapping is handled by QGC directly. It maps them to commands that are sent over Mavlink. But the turtle mode is something specific built into the ESC driver. For the joystick buttons to work for turtle mode you need to set VOXL_ESC_MODE to 1. For newer versions of thevoxl-fpv-devbranch you can also set VOXL_ESC_MODE to 2. The verify that the button mapping is working you can look at the manual_control_setpoint topic in px4 and see if the aux1 / aux2 fields are changing between 0.0 and 1.0. (e.g.px4-listener manual_control_setpoint) -

I tested what you asked me, since i am using external Fc and doodle labs, I am not able to assign AUX to any button, is there any work around on how to assign AUX -

hey guys, just a random thought, can I enable turtle mode through a button instead of taking AUX 1 into consideration. just a thought, any guidance and help would be greatly appreciated. -

@Eric-Katzfey I am not able to see the option you have mentioned

@Eric-Katzfey I am not able to see the option you have mentioned
VOXL_ESC_T_ON@Jetson-Nano said in doodle labs and joystick setup:
I am not able to see the option you have mentioned VOXL_ESC_T_ON
In the Mavlink console what do you see with "param show VOXL_ESC_*"?
And what about "ver all"?

@Eric-Katzfey Hey hope you are doing fine, I checked the code and various branches of PX4, I noticed I was able to see the parameter
VOXL_ESC_T_ONbut the option only showcased button 1 for assignment . what to do if I want to assign another button. -

@Eric-Katzfey Thank you for reverting back, The options only show one option button 1. I tested with button one but the drone was not taking in the command for enabling the turtle mode.
I want to know whether the code was tested out, so that I can be sure about not missing out on any parameter or setup -

In QGC you can look at the joysticks tab and see as you press each button which number it is. Then set the parameter to that number.

@Eric-Katzfey I am not able to setup multiple buttons, it is only showing one option of
button 1.
Also after assigning the button one and trying to enable and use turtle mode, it is not working.
Is there any particular version of px4 that this works with.
My setup is VOXL 2 ---> TELEM 1 --> Flight core v2 --> TELEM 2 --> FPV ESC
In normal setup the motors are working and rotating, but when I try to keep the drone upside down and enable the turtle mode , the QGC is still showingnot readymessage. Also I am not able to ARM because of this.
Is there anything I am missing out? -

@Jetson-Nano Let's try to walk through this and see where it is going wrong. Please provide answers to all of the following questions. Go to the joystick tab in QGC and press the button on the joystick that you want to use for turtle mode. Which number lights up when you press the button? Next, go to the MAVLink console and provide the output of these commands:
ver all,listener manual_control_setpoint,param show VOXL_ESC_MODE,param show VOXL_ESC_T_ON, andparam show COM_RC_IN_MODE. If VOXL_ESC_T_ON is not set to the number of the button you just discovered on the joystick tab then change it to the value you want. For example, by default VOXL_ESC_T_ON is set to 9. If you want to use button 10 instead then doparam set VOXL_ESC_T_ON 10. If you had to change that parameter then reboot and verify that it is now set correctly. You should see the aux1 value in manual_control_setpoint change from 0.0 to 1.0 when you press the button that you have chosen. Can you verify that you are seeing that? -
@Eric-Katzfey could you please help me out here
@Jetson-Nano If all that seems to be working then press the turtle button and arm (with drone right side up, not upside down) and verify that with turtle mode enabled the propellers are spinning in the opposite direction and the drone won't lift off. Of course, you must be extremely careful when running this test!!! Make sure that the drone is in a location where it cannot cause damage or injure someone if it goes out of control. It would be best to completely remove the propellers and just verify that the motors are spinning in the opposite direction of normal flight.
