I am using the evaluation board for testing the ADE7878 and I have seen the "Quick Startup" function in the Evaluation Board Software.
Could I use this function to calibrate all the necessary Registers into the ADE7878 ?
I got the ADE7878 working.
I think the problem is with the ground connection. I got a new ADE7878 IC and dead bug soldered it on a prototype board. Now everything works fine. There was nothing wrong with the crystals.
I have a old relay…
I am developing an energy metering system. At the moment I use the ADE7878 evaluation board with a
STM32 microcontroller. Currently I use the optocoupler on the ADE7878 board. I am at the point
that I have to think about designing a pcb.
I have a problem during calibrating for ADE7878:
I used to calibrate ADE7878 and xVRMS, xIRMS operates right and my input voltage = 240 V and Current = 5A,PF =1. I expected value near WATTHR =1200. but the xWATT registers always give the wrong val…
I have attached the Gerber files for the ADE7978 board and the file for the layout surrounding the ADE7878. I don't have the full evaluation board layout for the ADE7878, although I am not sure if that would be useful since the ADE7878 eval…
When using ADE7878 for voltage and current aquisition,we met some problems.The input voltage is coupled to ADE7878 by PT,when its range changes from 0 to 220V in a very short time,we found that the data from HSDC is incorrect.Below is the schematics…
I am working on interfacing ADE7878 with PIC24 microcontroller through SPI communication.I am able to read and write into any of the ADE7878 registers.
Now i want to monitor the VRMS , IRMS etc. , calibrate the values to respective inputs, hence…
