This book is a good introduction to readers who are beginners in the world of embedded programming and real-time operating systems. I have read several books on real-time this is one of the most complete because it references the real time concepts and contain real examples. This is Micirum's first ARM Cortex-M4 book. The information is presented in such a way that it can easily be applied to any RTOS. I like the real medical example based on: Heart Rate Monitor, Blood Glucose, Pulse Oximeter, and Blood Pressure Monitor. It also has a good section about certification process for medical Devices.
All firmware including µC/OS-III source code available for evaluation at:
