@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

@Eric-Katzfey For turtle mode with a joystick you need to set VOXL_ESC_MODE to 1 and, while not armed, press a button and keep it pressed while arming. For flight modes that should all be handled through QGC.

Jetson Nano

@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-dev is the name of the branch. The version will be a number, such as 1.14.0-8.104.3. 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 the voxl-fpv-dev branch 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)

@Eric-Katzfey Thank you for the support. I will test it out and get back to you encase of any further queries.

@Eric-Katzfey
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

Jetson Nano

@Eric-Katzfey @Alex-Kushleyev
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

@Jetson-Nano What do you see if you go to the MAVLink console in QGC and look at the manual_control_setpoint topic? (listener manual_control_setpoint)?

Eric Katzfey

@Eric-Katzfey Also, there is a parameter called VOXL_ESC_T_ON. How is that set? It determines which button will be used for turtle mode. The code is here: https://github.com/modalai/px4-firmware/blob/ea098200d3c09b7af548bf7be29fda245fad8f17/src/modules/mavlink/mavlink_receiver.cpp#L2083

@Eric-Katzfey 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"?

What is the parameter COM_RC_IN_MODE set to?
