The communication system, especially the Internet, is playing a more and more important role in daily life, and it is developing rapidly. Today, Internet access is no longer the exclusive domain of personal computers and network workstations, and many embedded system controlled by microcontrollers (or microcontrollers) have become part of the Internet's network of nodes, often, this embedded system can be called an embedded Internet terminal. Imagine, if through the web browser, can complete the remote control of the Microcontroller, and can receive the signal collected by the Microcontroller, that will bring great convenience to people's lives and greatly promote the development of productivity. CS8900A low power consumption ethernet controller is widely used in industrial computer. Its high integration design (only a few peripheral components are needed in the application) and simple bus interface are very suitable for this design. At present, many ethernet controllers only provide PCI (peripheral component extended interface) interface, and CS8900A can be directly connected to the Microcontroller, so, you can MSP430F149 I / O interface to directly control the CS8900A, as shown in figure 2. In addition, the CS8900A can be powered directly by 3V, which facilitates a level match with the MSP430F149. With the development of network technology, more and more micro embedded Internet terminals are needed for network connection and communication, which can be used not only in daily life, but also in many industrial fields, especially in those scattered, sharing data or need to share some information of the industrial field embedded network terminal technology quality is more obvious. In addition, MSP430 series, SCM, the power consumption is very low, a good solution in some special occasions under the power problem. Speech Recognition Control Circuit Module, the image recognition system recognition function mainly through the software system to achieve, in order to improve the program portability. In order to reserve space for the function expansion of the system in the future, the whole software system adopts the method of sub-module and hierarchical programming, and adopts assembly language to realize the read / write of register and the control of interrupt, and provide a flexible interface for the development of the upper level, the upper level using C language, through calling the lower level functions to operate indirectly on the hardware resources, so that the program is written to make the whole system structure clear, the transplantability and expandability of the program are enhanced, and it takes up less hardware resources, which reserve sufficient space for the expansion and further development of the system function. SPCA563B embedded powerful image color processing DSP, it is very convenient and fast to use it as the main control chip of image recognition system. At the same time, the system has voice output prompt function, the operation is more humanized, and can communicate with PC through USB1.1 interface, cooperate with PC debugging tool, and can greatly shorten the development cycle of image recognition function.
