Grumpy_Mike:
Not very valid. The Arduino code is open source, you already have the source code for that function in the IDE already. If you want to know what happens then look at the code you already have.
That's what I did, but I did a copy-paste error.
And things like that happen easily, as you have to work through heaps of pin-mapping and other stuff.
There there are tons of initialization code, I thought my code didn't work because of some stuff from there.
But I am sure you have never made a mistake like that, so I apologize for my stupid behaviour.
I am only human and I thought, the purpose of this forum is to ask questions.
Now I understand, it's here to praise you.
Grumpy-Mike, you are the best!
