I just replaced an old ethernet shield with the v5 hoping it would cure the reset problem.
Now I can't get proper readings from A0, A1. Turns out on the schematic they're labelled WP and Detect and seem to be in use. They're not mentioned as being used on the shield's webpage though. What are they for? Why are they there? Looks like I'm going to have to rewire my own protoshield to work around this but I really am curious why this has been done.
What is going on???
