This book describes the design and implementation of mC/OS-II (pronounced "Micro C O S 2") which stands for
Micro-Controller Operating System Version 2. μC/OS -II is based on μC/OS, The Real-Time Kernel which was first
published in 1992. Thousands of people around the world are using μC/OS in all kinds of applications such as
cameras, medical instruments, musical instruments, engine controls, network adapters, highway telephone call boxes,
ATM machines, industrial robots, and many more. Nu merous colleges and Universities have also used μC/OS to
teach students about real-time systems.
μC/OS-II is upward compatible with μC/OS (V1.11) but provides many improvements over μC/OS such as the
addition of a fixed-sized memory manager, user definable callouts on task creation, task deletion, task switch and
system tick, supports TCB extensions, stack checking and, much more. I also added comments to just about every
function and I made μC/OS -II much easier to port to different processors. The source code in μC/OS was found in two
source files. Because μC/OS-II contains many new features and functions, I decided to split μC/OS-II in a few source
files to make the code easier to maintain.
If you currently have an application (i.e. product) that runs with μC/OS, your application should be able to run,
virtually unchanged, with μC/OS-II. All of the services (i.e. function calls) provided by μC/OS have been preserved.
You may, however, have to change include files and product build files to ‘point’ to the new file names.
This book contains ALL the source code for μC/OS-II and a port for the Intel 80x86 processor running in Real-Mode
and for the Large Model. The code was developed on a PC running the Microsoft Windows 95 operating system.
Examples run in a DOS compatible box under the Windows 95 environment. Development was done using the
Borland International C/C++ compiler version 3.1. Although μC/OS-II was developed and tested on a PC, mC/OS-II
was actually targeted for embedded systems and can easily be ported to many different processor architectures.
