Hi guys
I am currently doing a design project which has an energy metering system. A subsection requires me to configure the analogue inputs for the ADE7757 in the datasheet the current channel requires a 350uohm resistor however i am using a 1000:1 current transformer. I need some assitance calibrating/configuring the chip. I need to select a base current for a 40amp max current and obtain the value to calculate frequency output using the CF output which is being interfaced with an atmega16.
Any advice will be of help.
Thanks
NB. I cannot use adruino
