Microcontrollers are embedded into larger systems to provide benefits such as better performance, more features, better efficiency, lower costs and better dependability. This textbook introduces students to creating microcontroller-based embedded systems featuring an ARM Cortex-M CPU core.
Chapter 1 introduces students to the concepts of MCU-based embedded systems, and how they differ from general-purpose computers. It then introduces the ARM Cortex-M0+ CPU, the Kinetis KL25Z MCU, and the low cost FRDM-KL25Z MCU development board.
Chapter 2 presents the general purpose I/O peripheral to provide an early, hands-on experience with reading switches and lighting LEDs using C code. It also introduces the CMSIS hardware abstraction layer, which simplifies software access to peripherals.
Chapter 3 introduces multitasking on the CPU, with the goals of improving responsiveness and software modularity while reducing CPU overhead. The interplay of interrupts, peripherals and schedulers (both cooperative and preemptive) is examined.
Chapter 4 presents the ARM Cortex-M0+ processor core, including organization, registers, memory, and instruction set. It then discusses interrupts and exceptions, including CPU response and hardware configuration. Designing software for a system with interrupts is discussed, including program design (including partitioning work), interrupt configuration, writing handlers in C, and sharing data safely given preemption.
Chapter 5 first gives an overview of tool-chain which translates a program from C source code to executable object code. It then shows side-by-side the source code and the object code the tool-chain has generated to implement it. Topics covered include functions, arguments, return values, activation records, exception handlers, control flow constructs for loops and selection, memory allocation and use, and accessing data in memory.
Chapter 6 presents analog interfacing, starting with theory and ending with practical implementations. Quantization and sampling are presented as a foundation for digital to analog conversion, and analog to digital conversion. The DAC, ADC and analog comparator peripherals are presented and used.
Chapter 7 presents timer peripherals and their use for generating a periodic interrupt or a pulse-width modulated signal, or for measuring elapsed time or a signal’s frequency. Watchdog timers, used to detect and reset an out-of-control program, are also discussed. The SysTick, PIT, TPM and COP timers are examined.
Chapter 8 discusses serial communications, starting with the fundamentals of data serialization, framing, error detection, media access control and addressing. Software queues are introduced to show how to buffer data between communication ISRs and other parts of the program. Three protocols and their supporting peripherals are investigated next: SPI, asynchronous serial (UART) and I2C. UART communication is demonstrated using the FRDM-KL25Z’s debug MCU as a serial port bridge over USB to the PC. I2C communication is demonstrated using the FRDM-KL25Z’s built-in 3 axis accelerometer with I2C interface.
Chapter 9 introduces the direct memory access peripheral and its ability to transfer data autonomously, offloading work from the CPU and offering dramatically improved performance. Examples include using DMA for bulk data copying, and for DAC-based analog waveform generation with precise timing.
An appendix covers how to measure the power and energy use on the FRDM-KL25Z board, including disconnecting the debug MCU to reduce power. Energy measurement using an ultracapacitor is also presented.
For use in ECE, EE, and CS departments.

Give your students an understanding of the most important topics in embedded systems design using a coherent, compelling and hands-on approach. Now in its 2nd edition, this textbook has been updated on a new development board from STMicroelectronics - the Arm Cortex-M0+ based Nucleo-F091RC. Designed to be used in a one- or two-semester introductory course on embedded systems, the textbook covers fundamental topics including the CPU, interrupt systems, peripherals, serial communication and multi-tasking. Software examples in this textbook are written in C and the free version of Arm's Keil MDK-ARM integrated development environment is used throughout the materials.

Embedded microcontrollers enable products with sophisticated control, precise timing, low unit cost, low development cost, and high design flexibility. This book shows how to design and optimize embedded systems using the energy-efficient RL78 family of microcontrollers from Renesas Electronics Inc. The book is suitable for practicing engineers and both undergraduate and graduate classes on embedded systems. The first section of the book provides an introduction to developing embedded systems efficiently. - Basic microcontroller concepts - Processor core, instruction set architecture and interrupt system - Peripherals for digital and analog interfacing, serial communications, timing control, system robustness and acceleration, clock system control and low-power standby modes - Software development concepts including software engineering, development tool-chain, and compiler concepts The second section dives into optimizing embedded systems for three different goals. - Program speed depends on designing an efficient program and then helping the compiler generate fast object code. Execution time profiling finds the slow parts of the program quickly and guides speed optimization efforts. Examining object code helps determine if the compiler is working well enough. - Program responsiveness to events depends on the task scheduling approach and the use of preemption and prioritization. Real-time system analysis enables the calculation of response times and schedulability. - System energy efficiency depends on balancing a system's static and dynamic power consumption. A good design will trade off supply voltage, operating frequency, standby and shutdown modes to meet energy or power goals.

Billions of microcontrollers are sold each year to create embedded systems for a wide range of products. An embedded system is an application-specific computer system which is built into a larger system or device. Using a computer system offers many benefits such as sophisticated control, precise timing, low unit cost, low development cost, high flexibility, small size, and low weight. These basic characteristics can be used to improve the overall system or device in various ways: • Improved performance • More functions and features • Reduced cost • Increased dependability This book uses the Renesas RX62N family of processors to demonstrate concepts with hands-on examples complete with source code targeting the YRDKRX62N evaluation board. The 32-bit RX processor core provides remarkable instruction throughput, with high clock rates and hardware support for floating-point and digital-signal processing instructions. The core is also quite agile, responding to fast interrupts in 5 clock cycles. These processors offer a wide range of sophisticated peripherals to simplify interfacing with and controlling external devices.
