If you look at the code you can see that
I use port3 entirely for the lcd so r/w, rs and e are connected to that port too. I connected everything to one port because you can't drive 2 ports at the same time and i thought that this was neccisary.

Contrast schould be ok. the first line is black at startup and the second is white.

but after init the cursor should blink and this is not happening.

Are mij init bits ok?
