Hi friends,
How to measure isolated mains voltage without using isolated transformer?
can we put an opto isolator on port pin?
you
regard
whatever "I Can't Spell Quartus" has to do with
can we put an opto isolator on port pin? the answer is yes, read datasheets till you find one that match the isolation and gain you need

The big question here: Should someone who don't have the electrical knowledge about different methods to measure mains voltage really measure mains voltages?
ni hao friends.
that why asking for opto isolator. no mains for me ^-^
Quartus method splits problem for easy solution.
Does it?
