[lcd4linux] Re: lcd4linux dependencies

Hi Adrian,

First, please post such questions to the mailing list.

No, I'm afraid I can't. There are some dependencies for special display
drivers (ppdev, libusb, X11, libgd, ...) but that depends on which
display you wanna use.

Most of the dependencies should be detetcted by autoconf, it shoud
deactivate drivers and plugins whose dependencies are not fulfilled.

I' suggest you download lcd4linux, try a 'configure --with-drivers=<your
driver>' (e.g. 'HD44780') and see what happens.

If you have any further questions, please let us know!

I'd be glad if you could summarize your experiences (and maybe a
'microhowto') about lcd4linux on smoothwall in the wiki!


bye, Michael

[lcd4linux] Support for Sharp Graphic LCD?

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

I all,

I just found a graphic display (320x240) which I want to use with lcd4linux,

Now It says that the display uses 4-bit mode and two drivers, as stated:

Segment driver: LH1560F3*2 (SHARP)
Common driver: LH1562F4*1 (SHARP)

Is this Graphic LCD display supported? I dont know whether the sharp
drivers are the same as the toshiba ones,

Here is a link to the datasheet if you need more info:

Hi there,

320x240 would be cool! Where have you got the display from?

I'm afraid it is not, at least not at the moment.

If you mean the T6963 by "Toshiba", I'm quite sure they're not.

Well, this is probably the funniest data sheet I've ever seen: It
contains a process diagram of their quality assurance department, but no
real technical description of the display.

At the moment the farnell page is down (at least I cannot reach them),
but yesterday I did a bit googeling on the "PG320240" IIRC, and found
some pages about VDR's graphlcd-plugin... I read something about SED1330...

If you can provide any additional info about this display, I'm shure we
can write a driver together.


bye, Michael

I havent got It yet, its selling on ebay and I wanted to check if its
supported before I bid.

perhaps that why the product failed ;)  The farnell page states that the
product is no longer sold.

The product can be seen here:

the auction states that its made by a company called Powertip. And I
know about the existence of the SED display controllers so hopefullly it
is of a more well known design.

Well, I havent got the display yet, we will see how much it goes for. If
lucky and I get it I wouldnt mind helping you (after all I do want it to
work with linux :) ).

As long as I dont have to do any coding, becuase I havent got a clue
about C programming (still learning python :P ) .
