I know this is maybe embarrassing but I'm really newbie at this.. The pin S1,S0 description at ADE 7751 said "These logic inputs are used to select one of four possible frequencies for the digital-to-frequency conversion" and so G1, G0 with their logic input for gain selection.. My question is...
I'm using an AD7751 energy metering IC and ATMega32. I connect the PIN22 (CF) from AD7751 to PIN1 ((T0/XCK)PB0) from ATMega32. I want to calculate the energy by calculating the frequency from CF, how do I make this happen? I've set the operation mode to synchronous but I'm confused how to...
I don't know with for sure because this is my first time designing a energy meter. It will be used for measuring electric vehicle and pv, do you have any suggestion what will be the max DC current?
I have project to design a tool to measure DC energy meter foe electric vehicle and pv. Please tell me which IC and microcontroller I should use. And If you have any references for this project, please share.
Thanks.
