Hi Coline, thank you very much, I found out that, 500, was the neutral value as you said. My problem was that the behaviour in manual mode was different and confused me.
Now I can control the drone (in the simulator) using the manual_control message and the POSCTL flight mode, as expected.
The only dubt now, is about tha yaw. In the message description says:
R-axis, normalized to the range [-1000,1000]. A value of INT16_MAX indicates that this axis is invalid. Generally corresponds to a twisting of the joystick, with counter-clockwise being 1000 and clockwise being -1000, and the yaw of a vehicle.
To me it’s not clear the corresponding degree value. I mean, is 1000 corresponding to a 360° yaw or what?
And [-1000,1000] is the real range of values? (the message description says -1000,+1000 even fro the ‘z’ but the right range is 0-1000)
Do you have an idea?
