[lcd4linux] LCD with icon support

[Michael M. <im...@im...>]

Hi everyone,

I'm about to buy a new LCD for my linux box for different kind of monitor=
ing.
I've got some questions I hope you can answer:

- Are crystal fontz graphic lcds supported? (I assume no?)
- Which LCDs support the logos announced in the news? (animated gifs)
- Can anyone point me to a LCD that is working great with lcd4linux with
an external case? (I like the CF 634XE, but I didnt manage to find a shop
in Germany offering that one).

Thanks in advance!

best regards,
Michael

Hi Michael,

> - Are crystal fontz graphic lcds supported? (I assume no?)
I'm afraid not at the moment. I don't have such a thing. But if anybody
out there owns one, I could write a driver 'blindly', but I need a tester...

> - Which LCDs support the logos announced in the news? (animated gifs)
All Displays that support user-defined chars (there are only very few
that don't, and these do not support bars, too.

This device looks cool! (but it's a bit expensive)

Sorry, I hit 'send' too early :-(

If you wanna have an external display, USB is the best choice (because
the power supply is taken from USB, too).

There are some USB-to-HD44780 adapters, one is the USBLCD
(http://www.usblcd.de) but this company seems to be out of business.
Another one is BWCT (http://www.bwct.de/lcd.html) and Trefon
(http://www.trefon.de/)

I hope I did not forget one...


HTH, Michael

Hi Michael,

thanks for your fast reply.

Very good. I just attempted to use Icons with the ncurses display driver
and got the message that the icon class is not supported by the widget
which seemed to be caused by the display driver. Are you planning on
improving the ncurses driver to support icons as well? With the image
display driver it working fine.

yeah, unfortunately :( And nowhere near available. Taxes and shipping
costs from the US would probably exceed the lcd's worth.

I wrote a mail to usblcd some days ago but got no answer so I think you'r=
e
right. BWCT and Crystalfontz (634) both offer nice usb lcds (no case but
if everything else fails, I'll try to build one myself).

Yes it did indeed. Thanks a lot.

It's impossible to use icons with the curses driver, because there's no
way the change the bitmap of a character in curses (at least not to my
knowledge).

The X11 driver does support icons.

I did build one. It's a standard HD44780 4x20, with blue backlight, I
used the USBLCD (I got one years ago), and I used a plastics case from
Conrad. It's quite easy, the only issue is the clearance for the display.


bye, Michael
