8.6 Set Axis Velocity Profile (#28)
Firmware Version:
Version 5.04 and up
Command Number:
28
Data Bytes:
1 to use linear profile
2 to use squared profile
3 to use cubed profile
0 to toggle through the different profiles
Reply Data:
1, 2, or 3 depending on the current velocity profile.
Note:
This setting affects only the active axis. See the Set Active Axis (#25) command
for instruction on how to select an axis. This setting is stored in non-volatile
memory and will persist after power-down or reset.
This setting allows the user to select the desired relationship between the angular displacement of the active
joystick axis and the velocity of the unit controlled by that axis.
When the joystick is displaced from the neutral position, the T-JOY3 reads the angular position and
calculates how fast and in which direction the corresponding units should be instructed to move. There are
three different profiles that can be selected:
-
1 – Linear
-
2 – Squared (factory default)
-
3 – Cubed
The maximum velocity is set by the Set Axis Velocity Scale (#29) command. Squared and cubed curves
offer finer control at slow speeds, but still allow maximum velocity when the joystick is fully deflected.
