Design Of Embedded System Platform Based On TMS320LF2407A And Applications Of Networks

Embedded system is based on application-centered hardware design and software development facing application. Embedded systems are widely applied in such areas as manufacture, process control.With the development of information, networks and IC technology, the direction of development of embedded system is multimedia and networks, especially, combination of Internet or wireless networks. It is convenient for people to enjoy the pleasure of life anytime and anywhere. "Embedded System+Intemet" have been the feature of the time of "post-PC".DSP is an important research field in embedded application.It has strong computation and control ablity. Adding network function will make DSP have strong communication ablity at same time. The data DSP input or DSP output can share with other network devices directly.On the chance of the development of networks based on embedded system, the thesis discusses the thought of the design of embedded system, in the background of reconstruction of network in the industry control system. This design built a hardware platform with ethernet communication system using TMS320LF2407A DSP and fast ethernet controller LAN91C111. Implement LCD,serial comunication and PWM of the system. Finally, implementation of the LwIP TCP/IP stack with its API functions, an embedded web server is built on this system. A detailed analysis of two kinds of network communication modes: C/S and B/S. In VC++ IDE, the GUI is given based on socket.Many models and porcessing flows in this design have much reference value, will offer some help in other embedded system except DSP.All of these efforts have prepared to discuss farther problems such as: the function expansion for embedded system, the connection and conversion between different networks and different protocols, the implementation of remote control, and etc.
