压缩包内为AD7190的通讯代码，使用模拟SPI程序编写，有很好的实用性~~~~~~~

此为AD7190的读写程序，并把读到的数据进行显示，存储。

AD7190原理图，做称重模块用的，只有原理图，经实测过可试用。

stm32 SPI 读取 AD7192

AD7190是一款适合高精密测量应用的低噪声完整模拟前端。它集成一个低噪声、24位Σ-Δ型模数转换器(ADC)。片内低噪声增益级意味着可直接输入小信号。 这款器件可配置为两路差分输入或四路伪差分输入。片内通道序列器可以使能多个通道，AD7190按顺序在各使能通道上执行转换，这可以简化与器件的通信。片内4.92 MHz时钟可以用作ADC的时钟源；或者，也可以使用外部时钟或晶振。该器件的输出数据速率可在4.7 Hz至4.8 kHz的范围内变化。 在1KHz时能得到16位无噪声分辨率，提供STM32例程，移植简单，非常适合力传感器的输出信号处理。
