Chapter contents:
Chapter 1, Sample Code
This chapter is designed to allow you to quickly experiment with and use µC/OS-II. The chapter starts by showing
you how to install the distribution diskette and describe the directories created. I then explain some of the coding
convent ions used. Before getting into the description of the examples, I describe the code used to access some of the
services provided on a PC.
Chapter 2, Real-Time Systems Concepts
Here, I introduce you to some real-time systems concepts such as foreground/background systems, critical sections,
resources, multitasking, context switching, scheduling, reentrancy, task priorities, mutual exclusion, semaphores,
intertask communications, interrupts and more.
Chapter 3, Kernel Structure
This chapter introduces you to mC/OS-II and its internal structure. You will learn about tasks, task states, task control
blocks, how µC/OS -II implements a ready list, task scheduling, the idle task, how to determine CPU usage, how
µC/OS-II handles interrupts, how to initialize and start µC/OS-II and more.
Chapter 4, Task Management
This chapter describes µC/OS-II’s services to create a task, delete a task, check the size of a task’s stack, change a
task’s priority, suspend and resume a task, and get information about a task.
Chapter 5, Time Management
This chapter describes how µC/OS-II can suspend a task’s execution until some user specified time expires, how such
a task can be resumed and how to get and set the current value of a 32-bit tick counter.
Chapter 6, Intertask Communication and Synchronization
This chapter describes µC/OS-II’s services to have tasks and ISRs (Interrupt Service Routines) communicate with one
another and share resources. You will learn how sempahores, message mailboxes and message queues are
implemented.
Chapter 7, Memory Management
This chapter describes µC/OS-II’s dynamic memory allocation feature using fixed-sized memory blocks.
Chapter 8, Porting µC/OS -II
This chapter describes in general terms what needs to be done to adapt µC/OS-II to different processor architectures.
