Hi,
We are using an ADE 7878 development board and a 3.3V Arduino to communicate with it using SPI.
We were communicating with it successfully for a period of time but it has now stopped communicating at all.
PM0 is high and PM1 is low putting it into PSM0 mode.
I have noticed that the voltage on the DVDD pin is sitting at 1.5V.
AVDD =2.5V and Vref =1.2 V as expected.
I am not entirely sure what this shows. Is the ADE7878 not powering up properly?
Any guidance what to look at to try and resolve this would be greatly appreciated.
Kind Regards
Chris
