verilog实现的“状态机实现AD574数模转换”-verilog to achieve a " state machine to achieve AD574 digital-analog conversion"

vhdl编写，完成了对ad芯片ad574的控制，并将转化的数据存于fpga的内部存储器中，然后在发送出去。-vhdl prepared, completed ad control chip ad574, and conversion of data stored in the fpga internal memory and then sent.

AD574控制器的VHDL程序，用状态机设计的AD574器件的控制器FPGA硬件设计，可以代替单片机的功能-AD574 controller VHDL program, the state machine design AD574 device controller FPGA hardware design, can replace the function of the microcontroller
