Final project – motor control program

To demonstrate all the concepts we have covered so far, let's build a motor control program. The program will simulate five motors. The motors will be in an array and the program will set the speed of the motors based on a persistent variable. To begin, let us create a motor structure:

TYPE motorStruct :
STRUCT
     motorStateMsg : STRING[20];
     motorState    : BOOL;
     motorSpeed    : INT;
END_STRUCT
END_TYPE

This code will create a structure that will dictate whether the motor is on with a Boolean variable, the motor speed (which will be set with an enum value), and a string that will tell which state the motor is in. After this structure is created, add an enum named motorSpeeds. Once you create the enum, add the code to match the snippet:

{attribute 'qualified_only'}
{attribute 'strict&apos...
