4.7.2.5 ST_Vars_t

This is a structure that contains the user interface variables that should be used to operate on the SpinTAC components. This structure should not be declared in the main source file. It is already declared as part of MOTOR_Vars_t in main.h and main_position.h. More information about MOTOR_Vars_t can be found in the lab documentation.
