DK900-220 is one of the Evaluation and Demonstration Boards and Kits that can offer a quick and easy platform for evaluation, testing, design, and debugging. This device features an ARM9 26-bit CPU design pre-programmed with driver and sample code to construct an embedded system. It also features many peripherals such as LCD, Flash, Ethernet, and IDE connector for mounting 2.5 inch hard drive. With the use of DK900-220, users are able to develop an embedded system for real-time operation with the help of multiple debugging and programming tools.

The application fields for this Evaluation and Demonstration Board and Kit are quite varied. It can be used for the development of industrial automation, telecommunications, consumer electronics, power supply, and other related embedded systems. The basic features of DK900-220 include fast data transfer rate, low power consumption, low noise, and advanced debugging tools.

The basic working principle of DK900-220 is quite simple. It consists of a main board, a set of driver and sample code, an LCD panel, two Ethernet ports, and a Flash drive. The driver and sample code are designed to control all of the board\'s features and peripherals. The driver provides basic functions for controlling pins and port address settings, while the sample code offers functions such as access to memory, external I/O, and communication via the Ethernet ports. This is done by having the board act as a master device that is able to talk to other devices on the network.

In order to program the driver and sample code, users need to connect the board to a PC via Serial port interface. Once connected, users can use a debugging and development tool to upload the program, monitor the activity, and debug the system. This tool helps users implement functions such as creating driver, accessing registers, and more complex operations. Furthermore, the Flash drive allows users to store programs and data, while the LCD panel provides users with visual feedback.

In conclusion, the DK900-220 is an Evaluation and Demonstration Board and Kit that can offer a quick and easy platform for evaluation, testing, design, and debugging. With the wide range of features and comprehensive debugging tools, users are able to develop an integrated embedded system for their applications. This board works on the principle of providing a master device that acts as an interface between external devices and the board itself and controls all of the features and peripherals with its set of drivers and sample code.
