Category: C Programming

Overview
In this lab, you will use TI Code Composer Studio (CCS) to program the TC CC3220x LAUNCHXL to control an LED from the serial port using a state machine. This work will build on the concepts you learned during your activities in the zyBook this week.
During this milestone you will use CCS to edit, compile, and load code into the CC32xx board. You will then proceed to use it for debugging. Throughout this process, you explore the components of a CCS project and the CCS code generator (system config). You will also be able to learn more about the UART and GPIO drivers.
Goal: Your objective is to control the red LEDs in the lower right corner of the board (the corner opposite the USB connector). Use this to design a state machine to turn on an LED when a user types ON into the console and to turn off the LED when a user types OFF, using only one byte of RAM. Remember, you receive only one character at a time from the UART and it is not buffered. Then you will code the state machine you created.
Prompt
Begin your work by accessing the Milestone Two UART GPIO Lab Guide PDF document. While this document was written for a Windows interface, the tools can be used on Mac or Linux as well. Note that to accomplish the work outlined in the guide, you will need the following:
TI CC3220x LAUNCHXL
TI Code Composer Studio (installed)
USB connection between the PC and board
Specifically, you must address the following rubric criteria:
Develop code for all of the specified functionality. The goal of this criterion is for the code to result in the expected functionality (note how this is different from the state machine functionality). Both ON and OFF should operate as expected. In your video, show the terminal window and LED to make this clear.
Create code that reads characters from the UART. This must use only one byte at a time with no multi-byte buffering of the serial input. The characters are encoded back.
Create code that controls the LED on and off from the state machine. Note that this involves use of the GPIO peripheral. Partial credit may be awarded if the code does not work but you are able to successfully determine how to turn the LED on and off, then include it in the comments.
Implement (in code) the state machine functionality described by your documentation. The goal of this criterion is for the code to accurately reflect the state machine documentation, rather than for it to have perfect functionality.
Create state machine documentation to describe the operation that matches the technical specifications. This should be completed as a draw.io file and saved as a PDF.
Discuss the questions from the lab. Address all the questions thoroughly and thoughtfully, with supporting evidence from your work.
Apply coding best practices in formatting, commenting, and functional logic.
What to Submit
You will have four different file submissions for this milestone. Once you have completed your lab work, first zip your workspace and submit the zipped file for grading. Second, submit a 10-second video of the LEDs blinking on your board. If you encounter any difficulties filming the lights on your hardware component, reach out to your instructor. Third, submit a document containing your answers to the questions from the Milestone Two UART GPIO Lab Guide. Finally, submit a state machine diagram completed using draw.io and exported in PDF format.

h) Display “The product is” followed by the value of the int variable result.
3 Using the statements you wrote in Exercise 2, write a complete program that calculates the product of three integers
4 Write a single C statement or line that accomplishes each of the following (subtasks a, b, c and d are unrelated)
a) Display the message “Enter two numbers.”
b) Assign the product of variables b and c to variable a.
c) State that a program performs a sample payroll calculation (i.e., use text that helps to document a program).
d) Input three integer values and place them in int variables a, b and c.

Develop a program that will determine the gross pay for each of several employees. The company pays “straight time” for the first 40 hours worked by each employee and pays “time-and-a-half” for all hours worked in excess of 40 hours. You’re given a list of the company’s employees, the number of hours each worked last week and each employee’s hourly rate. Your program should use scanf to input this information for each employee and determine and display the employee’s gross pay. Here is a sample input/output dialog:
Enter # of hours worked (-1 to end): 39
Enter hourly rate of the worker ($00.00): 10.00
Salary is $390.00
Enter # of hours worked (-1 to end): 40
Enter hourly rate of the worker ($00.00): 10.00
Salary is $400.00
Enter # of hours worked (-1 to end): 41
Enter hourly rate of the worker ($00.00): 10.00
Salary is $415.00
Enter # of hours worked (-1 to end): -1Rubric

A palindrome is a number or a text phrase that reads the same backward as forward. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads in a five digit integer and determines whether or not it’s a palindrome. [Hint: Use the division and remainder operators to separate the number into its individual digits.
Please enter a five digit integer: 12345
12345 is a not palindrome number
Please enter a five digit integer: 12321
12321 is a palindrome numberRubric
