About this book:

"Embedded Systems Engineering: From Sensors to Real-Time Control" is a comprehensive guide to designing and developing reliable embedded devices. The book begins with foundational concepts, including microcontroller architectures, digital and analog I/O, and the principles of sensors and actuators. It then delves into the critical role of clocks, timers, and interrupts in establishing the temporal rhythm of a system, and the various types of memory (Flash, RAM, EEPROM, external storage) essential for storing code and data. A significant portion is dedicated to software architecture, exploring basic superloops, cooperative scheduling, and the robust framework provided by Real-Time Operating Systems (RTOS) for managing concurrent tasks, scheduling, and inter-task communication.

The text also provides practical insights into hardware and software debugging, covering tools like JTAG, SWD, and real-time tracing, alongside crucial testing methodologies such as unit testing, Hardware-in-the-Loop (HIL) simulation, and continuous integration. Communication protocols like UART, SPI, I2C, and CAN are detailed, followed by an exploration of wireless connectivity options including BLE, Wi-Fi, and Low-Power Wide-Area networks, with a strong emphasis on balancing range, data rate, and power consumption. Essential hardware considerations like power supply design, regulation (LDOs vs. switching regulators), grounding, and low-power optimization techniques are thoroughly covered to maximize battery life and system stability.

Beyond core functionality, the book addresses critical aspects of system resilience and security. It introduces the principles of functional safety, relevant standards (ISO 26262, IEC 61508), and strategies for fault tolerance, diagnostics, and watchdog implementations to ensure safe operation even in the face of failures. Security for embedded devices is explored through threat modeling (STRIDE), secure boot, secure OTA updates, hardware roots of trust, and cryptographic best practices. Finally, the book rounds out with advanced topics like control systems (PID, state machines) and signal processing (filtering, sensor fusion), concluding with the practicalities of production readiness, including manufacturing test, regulatory compliance (EMC, RF, safety certifications), and lifecycle management from provisioning to end-of-life.

Overall, the book emphasizes an end-to-end development philosophy, integrating hardware and firmware design to create dependable, efficient, and scalable embedded products. It aims to equip engineers with the pragmatic knowledge and mental models necessary to navigate the complex trade-offs inherent in designing devices for diverse applications, from IoT sensors to safety-critical industrial control systems.
