problem with dac channels
Posted: Sat Dec 11, 2021 4:52 pm
Hello everyone, I hope you can help me in some way.
The behavior of the dac channels is very confusing for me, and I would like to know if I miss something or it could be a fault on the board.
it turns out that when I use the dacWrite (25, 0);
I get 2.39v
and dacWrite (25,255);
will result in 0v;
I'm confused, because apart from it works in the opposite way, I don't get the 3.3v that I should get.
Any suggestion?
