You stated: 12f628. It should be PIC16F628 - big difference!

For you there is no difference between the PIC16F628 and PIC16F628A.

only one big black block.

check the source ... the

Code:

Contrast con   10       'regolazione contrasto display

line defines contrast as 10 - change this (use numbers between 0 and 250 .. 120 is much more likely to work then 10) - and you should have the picture on your screen.
