LCD wont work :(

Normally the contrast likes things on the "-" side. If you have a pot wire it like the example in the PBP manual. If not just try it going to the zero rail (-).

And PORTC 0-3 needs to be digital.

ANSEL = %00000000
That should turn all ADC off.
I think...

If I set Vo (contrast) to GND, I wont even get the black squares at start.

ANSEL = %00000000 <- I try that, no change.

If I use a voltmeter on PortC 0-3 all are logic low (0volt) idle. In start before the LCD initailized portC 0-3 are logic high (5volt), is that right?
