ucos ii英文教程,My first book, “μC/OS, The Real-TIme Kernel” is now 6 years old and the publisher has sold wellover 15,000 copies around the world. When I was asked to do a second ediTIon, I thought it wouldbe a fairly straightforward task; a few correcTIons here and there, clarify a few concepts, add afuncTIon 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’tsatisfied with minor corrections. Also, when my publisher told me that this time, the book wouldbe a ‘hard cover’, I really wanted to give you your moneys worth. In all, I added more than 200new pages, and re-wrote the majority of the pages I did keep. I added a porting guide to help youport μC/OS-II to the processor of your choice. Also, I added a chapter that will guide you throughupgrading a μC/OS port to μC/OS-II.The code for μC/OS-II is basically the same as that of μC/OS except that it contains a number ofnew and useful features, is much better commented, and should be easier to port to processorarchitectures. μC/OS-II offers all the features provided in μC/OS as well as the following newfeatures:·  A fixed-sized block memory manager,·  A service to allow a task to suspend its execution for a certain amount of time(specified in hours, minutes, seconds and milliseconds),·  User definable ‘callout’ functions that are invoked when:a task is created,a task is deleted,a context switch is performed,a clock tick occurs.·  A new task create function that provides additional features,·  Stack checking,·  A function returning the version of μC/OS-II,·  And more.
