Re: [Lcd-linux] Connecting HD44780 to AT91SAM9260

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

Hi,

low level functions are contained in the driver only, not in lcd-linux.c.

Therefore to make it work with (I presume) memory mapped access, you just need
to rewrite __read_display() and __write_display() in hd44780.c

Please tell me the outcome of your tests. It would be interesting to
add more platforms
to lcd-linux.

Regards,

Mattia
