INTRODUCTION With rapid development of information technology that is core of computer technology, communication technology and software technology, embedded systems have been widely applied in various industries, greatly promoted the application of industry permeability. According to IEEE (International Electrical and Electronic Engineers) is defined, embedded system is Devices used to control, monitor, or assist the operation of equipment, machinery or plants .Embedded system is composed of two parts that is embedded hardware and embedded software. Embedded hardware, including embedded microprocessor and peripheral function modules such as the various hardware components, hardware system design of the use of ARM architecture platform which has small size, high reliability and good real-time, storage capacity and other characteristics, is now hardware design of embedded system mainstream. Embedded operating systems including embedded software and embedded applications. People have already familiar with use of Microsoft’s desktop operating system and embedded operating system Windows CE is also increasingly popular. Microsoft launched Windows CE is 32-bit embedded operating system which has powerful compact, efficient, scalable, the main face of a wide range of embedded systems and products. The system has a multithreaded, multitasking, full preemptive characteristics is designed for a variety hardware system of strict resource constraints. In order to connect to operating systems and hardware devices, a driver program is very important which is a link between hardware and so
