基于DM9000网口芯片的DSP6713B网口扩展

Method for DSP6713B Ethernet Port Expansion Based on DM9000

网口在很多硬件板上已经被广泛运用。针对DSP6713B没有自带的网口问题,提出一种基于DM9000网口芯片扩展网口的方案。在该方案中,解决了DM9000网口芯片的驱动问题,完成了LWIP网口通信协议移植,实现了DSP6713B与PC机的TCP通信。实验结果证明,所提出的方案稳定、可靠。

Ethernet port is widely used in many hardware board. A mothed based on the network interface chip DM9000A is introduced in this paper in order to resolve the problem that DSP6713B doesn＇t have its own ethernet port. In this scheme, the driving problem of DM9000A is sloved, then completes the transplantion of LWIP ethernet port communication protocol, and achieves the TCP communication between DSP and PC. Experimental result shows that the system is high stable.
