please this assignment is for code design studio to use with msp 432 launchpad.

ONLY NEED STEP D E F

Blink LEDs with Timer0

A. Follow the Getting Started document Getting_Started_CCS.pdf to create a new CCS project for the MSP432 LaunchPad. You may name the new CCS project as Lab2_1.

B. Delete the main.c file if you have generated that file automatically when you were creating your new CCS project.

C. Copy the source code file Lab2_1_main.c into your project folder.

D. Build, load, and run your project on the LaunchPad.

E. Observe the LED blinking pattern on LaunchPad. Explain the code. The references that you will need to read are listed on the page titled References in the lecture notes. You will need to develop a habit of keeping those references handy and look up information frequently from those files. What you need to explain in your report include what the code in that file does, where the function is defined, what is the definition of the function, what are the input parameters, why the parameters are given the values as in the source code.

F. Stop debugging so your CCS returns back to the CCS Edit perspective.

this is the code
