Re: [Lcd-linux] lcd over gpio

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

Hi,

the implementation of GPIO lines would certainly be a valuable feature
to add to lcd-linux. Presently there is no plan to go in that
direction but it can be put in the TODO list. Another feature would be
to add an input line by using the input pins of the parallel port but
in my opinion the most urgent feature is to move from a parallel port
connection to something more modern and universal like USB.
Unfortunately for this you need to connect the display to a
controlling board. There is a wide choice of these boards but there is
no standard on their implementation so it is hard to tell what can be
supported or implemented.

Best

Mattia
