We are trying to configure a gimbal with PX4 1.7.3 on a Drotek Pixhawk 3 Pro.
Currently, the control is reacting in yaw, roll and pitch using passthrough RC channels but we are facing unexpected behaviour with the translation between the input and the output. We extracted a real-time preview displaying in green the RC channel (from min to max) and the corresponding output in blue which seems wrong. The same error can be observed for the other axises.
We tried to change values for MNT_OFF_YAW, PITCH and ROLL from 0 to higher or lower but it seems to not fixing this “offset”.
Thanks in advance for any feedback,
Hi there !
Any idea on this specific issue ?
Again, thanks in advance for any input that can help :).
Does changing MNT_OFF_YAW make a difference? Did you also try to change MNT_RANGE_YAW?
Changing the mentioned parameters - MNT_OFF_YAW - is indeed applying a offset to the value translated but still, the range for the output are incoherent.
The last try was to disable the MNT_MODE_IN, which is therefor using direct passthrough instead of the control group for gimbal. In this case, there is no “translatation” and value is correctly transfered.
Is there a way to know what is the correction applied by firmware when mount mode is active ?
Thanks in advance,
