Getting Started with μC/OS-III
μC/OS-III provides services to application code in the form of a set of functions that
perform specific operations. μC/OS-III offers services to manage tasks, semaphores,
message queues, mutual exclusion semaphores and more. As far as the application is
concerned, it calls the μC/OS-III functions as if they were any other functions. In other
words, the application now has access to a library of approximately 70 new functions.
In this chapter, the reader will appreciate how easy it is to start using μC/OS-III. Refer to
Appendix A, “μC/OS-III API Reference Manual” on page 375, for the full description of
several of the μC/OS-III services presented in this chapter.
It is assumed that the project setup (files and directories) is as described in the previous
chapter, and that a C compiler exists for the target processor that is in use. However, this
chapter makes no assumptions about the tools or the processor that is used.
