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

[Arjan Vroegop]

Hi,

According to the datasheet the memory address of the 2nd line should be 
0x40. For more information (and the datasheet) about the display I'm using 
see http://www.voti.nl/winkel/catalog.html?LCD-10

I've tried to send a very long string (80 or more chars) to the display, but 
nothing appears on the second line. Maybe this is an issue with the LCD 
itself and not the software or Ethernut board... I'll contact the shop where 
I've bought this LCD, maybe they have an answer.
