0 CDA3331C Intro to Microcomputers Lab Assignment Name/Semester: Grade: 15 [5] 0) This lab is designed to help students get acquainted with the MSP430 Launchpad microcontroller training kit. Type the following sample assembly language program which starts at address 0x0200 (&0200h), or simply $200. The program adds the contents of three consecutive memory locations starting at address $200. The sum is stored at location $206. In the following subsections, various commands are listed for you to explore. In the Code Composer, create a new Assembly Project and insert the following code into section label Main loop here. You can also copy the entire skeleton program from the text file provided on your Canvas course.
