Analog tab
The Analog tab contains settings that are specific to operation in Analog mode. Each of the four analog
inputs has the same options. Also, if in a different mode a pin is set for analog input, it is configured
here.
Calibration
Depending on what is generating the input signal, different calibration types are most appropriate.
Which other settings are active depends on the calibration type selected for the input.
Fixed Calibration
With Fixed calibration, the voltage levels for minimum speed, maximum speed and zero speed are pre-
defined and do not change during operation. This would be used with a potentiometer, a DAC or other
inputs that are well known and repeatable. Most of the time in Analog mode you will use Fixed
calibration. When using Fixed calibration, you can change the Input Min, Input Max and Input Center
values. For example, if you are controlling the Sabertooth from a DAC which has a maximum output
voltage of 3.0 volts, you would want to change Input Max to 3.0 and Input Center to 1.5.
Automatic Calibration
With Automatic calibration, the voltage levels are re-learned every time the motor driver is powered up.
This should only be used with input signals that self-center, such as joysticks. When powered up, after a
