AD7606是一款8通道最高16位200ksps的AD采样芯片。5V单模拟电源供电，真双极性模拟输入可以选择±10 V，±5 V两种量程。支持串口与并口两种读取方式。

硬件连接方式：

配置引脚	引脚功能	详细说明
OS2 OS1 OS2	过采样率配置	000 1倍过采样率 200K 011 2^3 8倍过采样率 200K/8=25K
RANGE	模拟信号量程配置	0表示正负5V, 1表示正负10V
STBY	待机省电	0有效可开启省电或关断，需配合RANGE脚， RANGE=1 待机 RANGE=0 关断
RESET	复位信号	典型值高脉冲50ns,上电后需给出，给出后转换中断，输出寄存器清零
CONVSTA	前半通道转换开始信号	控制前一半通道V1-V4，过采样末开启时启作用
CONVSTB	后半通道转换开始信号	控制后一半通道V5-V8。CONVSTA，CONVSTB可以并联使用
PAR/SER/BYTE SEL	并行/串行/字节选择	0 并行。1串行（DB15=0）或字节（DB15=1）串行时RD/CLK 作为时钟输入 DB7,DB8作串行输出字节模式下DB14=1 先高8位后低8位，0时相反串行或字节模式下不用数字接口需要接地
RD/SCLK	读取/时钟	并行模式：RD输入，RD=0 CS=0时开启输出总线串行模式：CLK时钟输入
CS	片选位	低电平有效
REF SELECT	外部/内部基准选择	0：外部基准 REF需要输入2.5V 1：内部基准 REF端可提供2.5V基准。
BUSY	忙信号	转换开始变高，转换完成变低。一般用下降沿来读数
FRSTDATA	首数据输出	首数据时为高，首数据结束时为低，初始为高阻态

并口读取STM32F407硬件连接
