MSP430 Microcontroller Lab Manual

This book is a practical reference for using Texas Instruments MSP430 microcontrollers. It provides a series of hands-on laboratory exercises. The labs may be completed in a traditional laboratory setting or at home using the Digilent Analog Discovery 2 Test Instrument. This book can be used as a reference for planning future projects using the MSP430 microcontroller. The authors focus on applications of the main peripheral modules available on the MSP430 microcontroller – CPU clock, Basic Input/Output, Timer, Analog-to-Digital Converter. They also provide examples of how to develop Pulse Width Modulation signals, and how to use Interrupts. 978-3-031-26643-0 1 Preface Background Approach and Organization Synopsis of Labs Synopsis of Helpful Reference Documents Acknowledgments Contents 978-3-031-26643-0_1 1 Lab 1: MSP–EXP430G2ET LaunchPad and Energia 1.1 Purpose 1.2 Energia IDE 1.3 Getting Started 1.4 Further Exploration 1.5 Post Lab Activities 978-3-031-26643-0_2 2 Lab 2: Introduction to TI Code Composer IDE 2.1 Purpose 2.2 Getting Started Guide 2.3 Prelab 2.3.1 Task A 2.3.2 Task B 2.4 Empty Project (with main.c) 2.5 Task C 2.6 Post Lab Activities 978-3-031-26643-0_3 3 Lab 3: Introduction to the GP Digital I/O Pins 3.1 Purpose 3.2 Discussion 3.3 Reading a Logic High Voltage at P1.4 3.4 Reading a Logic Low Voltage at P1.4 3.5 Switch Bounce 3.6 PreLab 3.6.1 Task A 3.6.2 Task B 3.6.3 Task C 3.7 Post Lab Activities 978-3-031-26643-0_4 4 Lab 4: Exploring the MSP430G2553 Basic Clock Module 4.1 Purpose 4.2 Discussion 4.3 PreLab 4.3.1 Task A 4.4 Task B 4.5 Task C 4.6 Task D 4.7 Post Lab Activities 978-3-031-26643-0_5 5 Lab 5: Interfacing a 16x2 LCD to the MSP430G2553 5.1 Purpose 5.2 Discussion 5.3 Prelab 5.3.1 Task A 5.4 Task B 5.5 Post Lab Activities 978-3-031-26643-0_6 6 Lab 6: MSP430G2553 ADC Module 6.1 Purpose 6.2 Discussion 6.3 Part 1: ADC Demonstration with LED (C Code) 6.4 Part 2: Demonstration with LCD Display (Assembly Code) 6.5 Post Lab Activities 978-3-031-26643-0_7 7 Lab 7: Timer_A Module of the MSP430G2553 (Introduction to Interrupts) 7.1 Purpose 7.2 Discussion 7.3 Capture/Compare Registers of Timer_0 and Timer_1 7.4 Up Mode 7.4.1 TIMER_UPMODE Code Listing 7.5 Continuous Mode 7.5.1 TIMER_CAPTURE Code Listing 7.6 Up/Down Mode 7.7 Interrupts 7.8 Post Lab Activities 978-3-031-26643-0_8 8 Lab 8: MSP430G2553 Timer_A Module (Pulse Width Modulation) 8.1 Purpose 8.2 Discussion 8.3 PWM_OSCOPE Code Listing 8.4 PWM_LED Code Listing 8.5 Post Lab Activities 978-3-031-26643-0_9 9 Lab 9: MSP430G2553 UART Serial Communication 9.1 Purpose 9.2 Discussion 9.3 Setting up the UART Demonstration 9.4 Post Lab Activities 978-3-031-26643-0_10 10 Lab 10: MSP430G2553 Applications 10.1 Introduction 10.2 Project 1: External Clock Sources 10.2.1 32.768 KHz Crystal Oscillator 10.2.2 Clock Oscillator 10.3 Project 2: 12 Button Keypad Matrix 10.3.1 How the Keypad Matrix Works 10.3.2 Sample Code: Reading a Positive Voltage at P1.4 (Switch Pushed) 10.3.3 Sample Code: Reading When the Switch Has Been Released (a ``0'') at P1.4 10.3.4 Digital Lock 10.4 Project 3: Reading the Contents of a Register 10.5 Project 4: Reading an LM34 Temperature Sensor 10.6 Post Lab Activities 1 (1) Appendix A Introduction to Digilent Analog Discovery 2 A.1 Purpose A.2 Introduction A.3 Overview A.4 Setting up the Wave Generator Function A.5 Setting up the Oscilloscope Function A.6 Setting up the Logic Analyzer Function A.7 Saving Images of the Screen Appendix B Distance Learning Lab Kit Appendix C MSP430G2553 Header File Appendix D Debug in Code Composer Appendix E Controlling a 16times2 LCD Display E.1 Introduction E.2 Interfacing the MSP430G2553 and the NHD–0216K1Z E.3 Sending Instructions to the LCD Display E.4 Configuring the LCD Display E.4.1 Commands and Examples Appendix F LCD Display Using C with the MSP430G2553 F.1 Overview F.2 Hardware Connections F.3 LCD Display C Code Appendix G How to Add Files into Code Composer Appendix H Tidbits–Useful Miscellaneous Information H.1 Introduction Appendix I Operators in C I.1 General Operations I.2 Arithmetic Operations I.3 Logical Operations I.4 Bit Manipulation Operations I.5 Unary Operations Appendix J UML Activity Diagram J.1 References
