• AD7790: Shift signals

    Sensor output is amplified so that signal lies between -3 and +3 V. System
    voltage is 3 V, -3V available from a voltage converter.
    Is it possible in some way to use the AD7790 as ADC in that case? What other
    possibilities are there to convert…

    Hi, 

    Thank you for your post but can we clarify which product are you referring? The title say AD7790 but the post it self uses AD7190 and I also see AD7730 in the code. Please let us know so we can help you better or we can re-direct you to the responsible…

  • SPI cannot get correct data from AD7790

    Hello, everyone:

         I'm using AD7790 for A / D conversion, and get data from AD7790 using the SPI function of STM32F103.

          I configured it according to its Timing Diagram. However, I could not get correct data from AD7790. I think I configured all the…

  • AD7790数据采集问题

    我在使用AD7790过程中,能够正常读到状态寄存器、模式寄存器、滤波寄存器的值,但是在读数据寄存器中,遇到了一个问题。

    读完一次数据寄存器后,再读状态寄存器判断数据是否就位时,就会始终无法得到数据就位的状态。

    我使用的是SPI通信,配置的是8位数据模式。

    AD7790除了数据寄存器是16位外,其他都是8位寄存器,我想是否和这个有关。

    求问我应该怎么配置才能一直得到数据寄存器的值?

  • AD7790用SPI采集不到数

    大家好,我最近在尝试用AD7790采集模拟电压进行AD转换。

    我使用STM32F103上的SPI与AD7790进行通信,按照它的时序图:

    我配置为第二个跳变沿采样,时钟极性设置为了高电平。

    具体配置如下:

    我按照AD7790的寄存器说明,先后对其进行了初始化、模式寄存器配置、滤波寄存器配置。

    但在通过数据寄存器读数时,无论怎样调试,我都无法通过SPI获得正确的数据。我甚至怀疑前面的配置根本没有成功。

    想请教一下,我应该如何配置,才能让AD7790正常工作。
