My first book, “µC/OS, The Real-Time Kernel” is now 6 years old and the publisher has sold
well over 15,000 copies around the world. When I was asked to do a second edition, I thought it
would be a fairly straightforward task; a few corrections here and there, clarify a few concepts,
add a function or two to the kernel, etc. If you have a copy of the first edition, you will notice
that “µC/OS-II, The Real-Time Kernel” is in fact a major revision. For some strange reason, I
wasn’t satisfied with minor corrections. Also, when my publisher told me that this time, the
book would be a ‘hard cover’, I really wanted to give you your moneys worth. In all, I added
more than 200 new pages, and re-wrote the majority of the pages I did keep. I added a porting
guide to help you port µC/OS-II to the processor of your choice. Also, I added a chapter that
will guide you through upgrading a µC/OS port to µC/OS-II.
