Micrium founder Jean Labrosse has just published a new book about a new release of MicroC/OS: uC/OS-III, The Real-Time Kernel, or a High Performance, Scalable, ROMable, Preemptive, Multitasking Kernel for Microprocessors, Microcontrollers & DSPs (Book & Board Included)

The MicroC/OS (a.k.a., uC/OS) family of real-time operating systems (RTOSes) has ranked in the Top 5 commercial operating systems for embedded software development in each of the past several years. This is because MicroC/OS offers a large value relative to its small price. Whereas other Top 5 embedded operating systems, including Microsoft's Windows CE/Mobile and Wind River's VxWorks, have per-unit licensing royalties and fees of tens of thousands of dollars per developer seat, MicroC/OS is royalty free, and has a total licensing fee less than one seat of those others. MicroC/OS even comes with C language source code and top-notch technical support.

This new book, by MicroC/OS creator Jean Labrosse, explains the design and API of the third generation uC/OS-III RTOS. This edition of the book adds a helpful focus on the design of application tasks that run on top of the RTOS; after all, you don't need to know how to write an RTOS; rather you need to use one. And this edition comes with an ARM-Cortex circuit board, compiler, and debugger so you can start experimenting with the RTOS right out of the box! All of that helps make the book a good value for money, just like the RTOS.

Users of uC/OS-II should note that the uC/OS-III API differs from the older API. In a nutshell, the API has been cleaned up for better internal consistency as well as to make the RTOS easier to use.
