HI all...
I'am interfacing ade7754 to my C8051F120 controller.
I have bought a evaluation kit with which i got familiar with.
The ade7754 is having 2 power supplies AVdd and DVdd.
The problem is :
I have connected THe SPI pins and a reset and irq pin is also needed
to interface with controller.
I need to know weather it is needed to short the grounds of the two devices.
Another problem is the cygnal kit is having 3.5volts as power supply.
but my ade7754 has 5V.
I guess using some buffer will do...But will there be much problem if i short the two grounds directly??
Suggest me a method to interface these two things...I'am sending a schematic. You can make corrections for that and post it in your reply.
Thanking you
