Serial Gimbal settings via CLI won't accept negative values #10572
Description
Current Behavior
Using CLI to center pan/tilt if using serial gimbal on UART (GM3 / C20T) gives very bad values.:
set gimbal_pan_trim = 50
gimbal_pan_trim set to 50
set gimbal_pan_trim = -50
gimbal_pan_trim set to 65486
set gimbal_roll_trim = 50
gimbal_roll_trim set to 50
set gimbal_roll_trim = -50
gimbal_roll_trim set to 65486
set gimbal_sensitivity = -16
gimbal_sensitivity set to -16
set gimbal_sensitivity = 15
gimbal_sensitivity set to 15
Steps to Reproduce
Try setting negative value for gimbal trim for pan and roll.
Expected behavior
Accept negative values if entered via CLI
