Lab 1 – Digital Logic Implemented on a Microcontroller Preparation Download, load into CCS, and run these five projects: GPIO_MSP432asm – Simple output InputOutput_MSP432asm – More complex with inputs and outputs Squarewaves_MSP432asm – Output to two pins SSR_MSP432asm – Output to one pin Switch_MSP432asm – Simple input from a switch and output to an LED Watch the related video(s) here Purpose The general purpose of this lab is to familiarize you with the software development. You will learn how to perform digital I/O on parallel ports of the MSP432. Software skills you will learn include port initialization, logic operations, and unconditional branching. Procedure The basic approach to this lab will be to develop and debug your system on the LaunchPad. Find the five example projects listed above. Compile, download and run all five projects on your LaunchPad and choose the one that best matches the problem. These four example project codes show the basic template for the first few labs. Make a copy of one that projects and rename it Lab 1. You will not need global variables in this lab. Write a flowchart for this program (see eq.(1)). I expect 5 to 15 symbols in the flow chart. Put this in Part 3.a of the lab report (see
the template document). Write pseudo code for this program (see eq.(1)). I expect 5 to 10 steps in the pseudo code. You may use any syntax you wish, but the algorithm should be clear. Put this in Part 3.b of the lab report (see the template document). You will write assembly code (see eq.(1)) that inputs from P1.1 and P1.4, and outputs to P1.0. If eq.(1) is true, then the red LED should be on. Otherwise, the LED should be off (see this video to see how it should work). Put this in Part 4 of the lab report (see the template document). P1.0 = (not(P1.1)) and (not(P1.4)) (1) Demonstration During the demonstration, you will be asked to run your program to verify proper operation. You should be able to single step your program and explain what your program is doing and why. You need to know how to set and clear breakpoints. You should know how to visualize Port 1 I/O in the debugger. Lab Report The lab report is how I will grade you on your labs. Usually, the report is due 1 week following the completion of the lab. However, do to unforeseen circumstances, due dates may change. I will try my best to keep everyone informed of any changes. With this said, it is your responsibility to turn the report in during the scheduled due
