分频程序

共两个文件，一个是对网络芯片W5500进行控制的master spi接口，另一个是w5500命令控制逻辑，命令格式按照w5500芯片的要求，分为地址段，控制段和数据段进行统一控制。此外提供w5500芯片初始化及读写控制流程图。(A total of two documents, one is the master SPI interface for network control chip W5500, the other is a w5500 command control logic, command format in accordance with the requirement of w5500 chip, divided into address segment, unified control and data segments. In addition to provide w5500 chip initialization and read and write control flow chart.)

Quartus II软件设计数字电子钟，使用verilog语言编写各个 模块生成symbol files，再用原理图方式制作顶层文件。 完成的功能有：能够显示时、分、秒；具有清零，调节分钟的功能； 具有整点报时功能，声响电路发出叫声； (failed to translate)

说明：  HDB3编码通过verilog实现，通过modelsim仿真(HDB3 coding is implemented by Verilog and simulated by Modelsim)

可以实现DDC各个模块的功能，如内插、抽取、FIR滤波等功能(DDC can realize the function of each module, such as interpolation, extraction, FIR filtering)

说明：  此程序为调试通过的程序，带有I2C总线功能的程序.(this procedure through the debugging process, with I2C bus function procedures.)
