A COMPREHENSIVE AND ACCESSIBLE INTRODUCTION TO THE DEVELOPMENT OF EMBEDDED SYSTEMS AND INTERNET OF THINGS DEVICES USING ARM(R) MBED(TM) Designing Embedded Systems and the Internet of Things (IoT) with the ARM (R) Mbed(TM) offers an accessible guide to the development of ARM(R) Mbed (TM) and includes a range of topics from the basic to the advanced. ARM(R) Mbed(TM) is a platform and operating system based on 32-bit ARM(R) Cortex-M microcontrollers. This important resource puts the focus on ARM (R) Mbed(TM) NXP LPC1768 and FRDM-K64F evaluation boards. NXP LPC1768 has powerful features such as a fast microcontroller, various digital and analog I/Os, various serial communication interfaces and a very easy to use web-based compiler. It is one of the most popular kits that is used to study and create projects. FRDM-K64F is relatively new and largely compatible with NXP LPC1768 but with even more powerful features. This comprehensive text is an ideal guide, divided into four sections: Getting Started with the ARM(R) Mbed(TM), Covering the Basics, Advanced Topics and Case Studies. This guide: * Offers a clear introduction to the topic * Contains a wealth of original and illustrative case studies * Includes a practical guide to the development of projects with the ARM(R) Mbed(TM) platform * Presents timely coverage of how to develop IoT applications Designing Embedded Systems and the Internet of Things (IoT) with the ARM (R) Mbed(TM) offers students and R&D engineers a resource for understanding the NXP LPC1768 evaluation board.Hinweis: Dieser Artikel kann nur an eine deutsche Lieferadresse ausgeliefert werden.
