The best reference for uC/OS-II is the following book:

MicroC OS II: The Real Time Kernel

Here are some tutorials on the subject:

What microcontroller (MCU) or processor are trying to development an uC/OS-II application?

Hi dhivya,

Rtos can be executed in simulated environment on the IDE itself ... the output can be seen on the PC. the other way or the real time output are seen by porting the RTOS and the user written program on a microcontroller and executing it for a real time application..

Since you are new to RTOS, its better you do it on simulator windows and then later go to controllers part..

read the attachment.. once you are done with it i will share more documents to you...

Micro-c OS II is very simple and easy to learn. it is also spelled as "ucos-c". once you learn it then you can port this on some 32 bit controller like lpc2129 or any version and run your program along with OS

Hi i need the link to downloadf the iDE for µcos-ii ..
 

There is no specific IDE for uC/OS-II. It is a source code package which you must, define tasks, configure and compile. So you could use several Embedded C IDEs, depending on the MCU you are porting the code.

you can use keil IDE if you are comfortable. or any IDE you are aware of... go to microc os website and download set of files called "ports" for specific target device and IDE and start using it... these files have to added in your project and compiled with your normal code....

Micrium - NXP

select the controller and download the required port code....
 

i did not get you bigdogguru... sorry for that... these ports are free and can be used easily on keil or IAR workbench... you just need to add these files to your project and complie it... where did Uclinux come here???

either i am mistaken or ????
 

Here are some tutorials which discuss the porting of uC/OS-II to ARM:
