How do you use the inertial senser

I am having some troubles programing my inertial senser in vex code pro without a drivetrain. I cant use a drive train because I am using mecanum wheels and you cant do that for mecanum wheels. i just need to turn 90 degrees. PLEASE HELP!!!

Its hard to help without more specific like what you want to do with it and what code platform you are using. Here’s a good article you should read about using the inertial sensor:
