Embedd-system Base On μC/OS-Ⅱ

With the arrival o f Post-PC times, the application of embedded system becomes popular. Now embedded technology has been the focal point of research. Embedded product have possessed great proportion in IT field. The embedded technology based on ARM has become a spot light of current embedded field.The paper mainly studies the implement of embedded real-time operating systems (μC/OS-Ⅱ) basing on the ARM7 LPC2104 and then designs the Embedded Systems Building Block based on LPC2104 and μC/OS-Ⅱ.1. Give the definition of embedded system and analyzes it.2. Analyzes the structure of μC/OS-Ⅱ' s nucleus and its code.3. Explains the approach and procedure about how to porting μC/OS-Ⅱ base on LPC2104 .4. Designs the working of COM port and PID controller base on LPC2104 and μC/OS-Ⅱ.5. At last, summarize the work had done and discuss the practice and development of Embedded System.
