Re: [Lcd-linux] [PATCH 1/1] Connecting HD44780 to AT91RM9200

[Mattia Jona-L. <mat...@gm...>]

Hi,

Great! Thanks writing the patch and testing! Did you also try the
"virtual screen feature", that is the possibility to have a virtual
display larger than the physical one?

Regards,

Mattia

The LCD is connected to the memory port and is mapped to address 0x40000000. The control lines are connected to the I/O lines. I think the code is self explaining and should be a good starting point for people who want to connect a LCD either to the memory port or the I/O ports of an ARM processor.
