User Mode
A major advance in the third generation Sabertooth motor drivers is the ability to have user-defined
operating modes. These are set up using a graphical scripting language in the DEScribe PC software and
uploaded over USB. In many cases, this removes the need for an additional microcontroller entirely. For
example, you could have main control be from a PC over USB, with a radio control override, or an analog
mode that only operates when the A2 input is between 2.2 and 2.5 volts.
Setup tab
To create a custom mode, the first thing that must be done is set up the inputs. On the Setup tab, select
how you would like each of the six inputs configured. If you will not be using that input, you may leave it
set as the default.
Signal Inputs
The options for each input will change depending on the Mode selected. These options are the same as
for that mode’s tab (Analog, R/C or Serial).
Indicator Outputs
Additionally, S2 and A2 can be configured as on/off 20 milliamp logic outputs. This is used to drive
external LEDs or signal to a host processor. If the mode is set to Indicator, you must select the source
that controls it.
