[lcd4linux] serial HD44780

[Ognjen B. <og...@ma...>]

Hi all,

I want to use a HD44780 2x24 LCD display with a linux box, but without
using up the parallel port (still use it for the
printer). I was wondering what other methods are there of connecting the
displays to the computer.

I know of the USB method, but was wondering of there are any other
methods. I googled about and came across
a project knows as LCD serialiser (project page:
http://www.mindspring.com/~tcoonan/lcd.html).

This seemed to fit my needs except that:

a) I do not have the required components - So does anyone know where I
can buy pre-assembled versions of these boards? I can build it, its just
that I would need to purchase quite a bit of kit (e.g. PIC programmer)
in order to do it.

b) There is no mention on the lcd4linux wiki about supporting this
project in particular (although there are references to serial-based
lcd's such as the lcd terminal emulator). Is there support for this
project in lcd4linux and if not, is it planned at all? looking at the
project it seems that the commands sent are the same (raw) command you
send to a hd44780 on a parallel port, except that its sent down a serial
link.

So is their any support for this? and if not, can anyone recommend an
alternative method of connecting lcd's to the computer.

Cheers.
