Hi!

Here is one of routines which I have been using for cursor's positioning for 4x20 characters display.

void GotoXY(char x, char y)
{
char addr;

switch (y) {
case 0:
addr = 0x80+x;
break;
case 1:
addr = 0xC0+x;
break;
case 2:
addr = 0x94+x;
break;
case 3:
addr = 0xD4+x;
break;
}
LcdCtrlRegister = addr;
LcdWait();
}

Regards,
Jacek
