Problem 1. Blink LEDs with Timer0. • Follow the Getting Started document “[login to view URL]” to create a new CCS project for the MSP432 LaunchPad. You may name the new CCS project as Lab2_1. • Delete the “main.c” file if you have generated that file automatically when you were creating your new CCS project. • Copy the source code file “Lab2_1_main.c” into your project folder. • Build, load, and run your project on the LaunchPad. • Observe the LED blinking pattern on LaunchPad. Explain the code line-by-line. 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 line 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. • Stop debugging so your CCS returns back to the CCS Edit perspective. Problem 2. Blink LEDs with SysTick timer. • Follow “[login to view URL]” to create a new CCS project with the name of Lab2_2. • Delete “main.c” if you have generated the file automatically. • Copy the source code “Lab2_2_main.c” into your project folder. • Build, load, and run your project on LaunchPad. • Explain the code line-by-line in your report. Problem 3. Square wave signal generation with SysTick timer. • Follow “[login to view URL]” to create a new CCS project with the name of Lab2_3. • Delete “main.c” file and then copy the source code “Lab2_2_main.c” into your project folder. • Make the following changes in the “Lab2_2_main.c” file: o Set DCO_FREQ to 48MHz o In addition to using P1.0 as an output, configure P3.7 as output pin. Then, toggle output on pin P3.7 at the same rate as P1.0.
