This book can assist you to learn about embedded systems using an MSP432 microcontroller. This fourth edition was written based on the use of an MSP432P401R MCU and Code Composer Studio. This book can be used as one of the supporting materials for microcontroller and embedded system courses. This book covers MSP432P4, GPIO, timers, display, interrupt, and ADC. Moreover, this book covers topics of software architectures, PWM, motor control, serial communications, TI Driver library, TI RTOS, Power management, and embedded system security. This book was written for undergraduate engineering students and the audience with prior knowledge about microcontroller applications.
