    Haa, this might explain everything! What's your clock freq.? Too high possibly. Anyway, I'll take a look at the code now.

    Did you know that sub delay100 actually delays only 1,4 ms!!! ? Otherwise code works OK (on PIC18F452). You must add delays:
    - before initializing LCD, about 100mS (use MPLAB-s simulator to check time)
    - delay about 2mS after sending cmd or data to LCD (in the lib file)
    See code.
