[En-Nut-Discussion] Multiline LCD: How to write on second line?

Do you have a datasheet? Perhaps your display uses a different memory
layout. Will say line two does not start at memory location 0x40 but
anywhere else... Try so send a long string with 80characters and figure
out where your second line starts. Next patch the hd44780 driver
appropriate (the part where the dcb is defined). You'll need to change
the virtual line width.
