verilog hdl写的利用fpga控制ad7865进行多路ad数据采集的程序源代码。

用FPGA控制AD7865的控制逻辑，状态机-AD7865 control logic

AD7865的verilog控制逻辑,可四通道一起采样，16位输出，高两位表示采集的通道号-control logic for AD7865

The AD7865 is a fast, low power, four-channel simultaneous sampling 14-bit A/D converter that operates from a single 5 V supply. The part contains a 2.4 μs successive approximation ADC, four track/hold amplifiers, 2.5 V reference, on-chip clock
