一个项目工程，硬件包含XINLINX FPGA，配置FLASH，串口，SDRAM,与以太网芯片DM9000A，实现数据采集，以太网传输，电路验证完全正确，请放心使用，SPARTAN 3E 的BGA引脚320个，不容易布板，可以参考使用的。要FPGA实现网络通信也可以参考电路，B因为产品升级了所以公开原来的电路的。 -A project engineering, hardware contains XINLINX FPGA, configuration FLASH, serial port, SDRAM, and Ethernet chips DM9000A, data acquisition, Ethernet transmission, circuit verification is completely correct, please rest assured that the use of, SPARTAN 3E' s 320-pin BGA it is not easy layout, you can reference to use. To achieve network communication FPGA also can refer to the circuit, because the product upgrades so publicly.
