Can't initialize a Qapass 1602A LCD with PIC18F4620
Hi to everyone, I can't initialize a QAPASS 1602A LCD with a PIC18F4620, I always get square blocks on both lines. At the beginning I tought the LCD was broken so I got a new one but the outcome is the same. I use a logifind PIC 40 Mini develpment board connected to PC through a PICkit3, everything else is working fine on every port but not the LCD.
Thanks a lot for your help.
