• RE: ADE7880数据校准问题

    谢谢您,问题一后来我想了一下,确实是,交流电流电压是没有方向的,虽然他们的寄存器(XIRMS,XVRMS)里24位带符号位的数据。

    有功功率和无功功率还有电能读数完全不正确我也想可能是有些寄存器设置问题,但是不知道有哪些地方需要设置的,我所有的寄存器设置都是采用默认值。具体如下:

    void ADE7880Cfg()

      {

       ADE7880.Write2byte_ADE7880(Gain,0x0000);

       ADE7880.Write2byte_ADE7880(CONFIG,0x0002…

  • RE: ADE7880 Power Up

    Hello Amit,

    Just to confirm, this is with the ADE7880?

    With the ADE7880, after you perform a hardware reset, you will need to perform the 8 steps I outlined above. The reset will reset the communication port and all the registers to the default settings…

  • Feed the ADE7880 through the ADC ?

    Hi,

    For my project, I am using the ADE7880. Everything works as I expected but I just have a little question.

    In my application, in some case the sensors will be plugged while there is no alimentation in the ADE7880's VDD.

    So there will be +-500mV…

  • RE: ADE7880 evaluation board software contents

    Good Morning Skating

    Some of the CD cntent are available on the ADE7880 webpage:

    http://www.analog.com/ade7880

    You will find the data sheet on this page.  If you then click on evaluation boards and tools and you will find the ADE7880 evaluation software…

  • RE: Resetting the cpu

    Hi Sanjay,

    I recommend you to configure ADE7880 to have CF outputs and observe the CF pin on oscilloscope with the inputs present. If ADE7880 resets, there will be no transitions on CF pin. This way you can determine if its ADE7880 or MSP430.

    What voltages…

  • RE: ADE7880 energy accumulation in case of power off

    Hi mallik

    ADE7880 will loose the data if there is no supply provided to the IC. Hence, in such a scenario, you would want to run the ADE7880 on battery when the power failure occurs, so that the accumulation continues seamlessly. Then you should save…

  • Polyphase Energymeter with Total Harmonic distortion

    Hi,

    We are using ADE7758 for our exist meter. In our new project we have chosen ADE7880 for poly phase with Total Harmonic distortion,

    1) Can we use ADE7880 for this application with SPI communication?

    2) ADE7880 is active for future production?

  • RE: Evaluation of ADE7858 and ADE7880 on the same evaluation Hardware

    Hi Meir,

    That is correct for the most part, the ADE7880 has the extra harmonic engine for detailed harmonic analysis, which is a strong point for that part. Although the ADE7858 measures only the total reactive energy while the ADE7880 only has a measurement…
