The book begins with an overview of the Cortex- M family, giving architectural descriptions supported with practical examples, enabling the engineer to easily develop basic C programs to run on the Cortex- M0/M0+/M3 and M4. It then examines the more advanced features of the Cortex architecture such as memory protection, operating modes and dual stack operation. Once a firm grounding in the Cortex M processor has been established the book introduces the use of a small footprint RTOS and the CMSIS DSP library.
With this book you will learn:
- An Introduction to the Cortex microcontroller software interface standard (CMSIS), a common framework for all Cortex M- based microcontrollers
- Coverage of the CMSIS DSP library for Cortex M3 and M4
- An evaluation tool chain IDE and debugger which allows the accompanying example projects to be run in simulation on the PC or on low cost hardware
Embedded systems engineers, undergraduates and graduates developing embedded applications.

Trevor Martin graduated from Brunel University in 1988 with an Honors degree in electrical and electronics engineering. In the same year, he began work as a junior hardware engineer at Philips Medical Systems. He joined Hitex in 1992 as a technical specialist for 8-bit microcontroller development tools. This included the 8051,68HC11\05\08 microcontrollers. He also gained experience with networking protocols such as CAN, USB, and TCP/IP. Since 2000, he has been supporting ARM-based microcontrollers, initially ARM7 and ARM9 CPU then moving to Cortex-M processor. To promote these devices, he has worked closely with both NXP and ST and also TI and Freescale to a lesser extent. Since 2005, he has written a number of “Insider’s Guide” books that are introductory tutorials to ARM-based microcontroller families such as LPC2000, STR9, and STM32. He also runs regular training courses, a general Cortex Microcontroller workshop and also device-specific courses.
