[Lcd4linux-devel] The HD66712-thing...

[<An...@t-...>]

Hello List.

Okay, i do some experiments. I still have no success with icons.
I compare it to the ouput of the XWindow Driver where all seems
to be okay. Just only the icons wont appear on the display. 
The bars and all other work fine. I would love the EKG in one
corner or anything like that. =)

I attached the Config File and the output of lcd4linux with -vvv
option. I dont think this helps much, cause i can see any 
relevant information regarding the Icons...?

Anyway i attached both, the config-file and the output.
The config file is nearly unchanged like its in the archive as i said.
The errors are okay, i guess since i configured nothing in this direction.

I would be glad if i can help this thing get to work.

Thanks in advance,
Andreas

Hello Andreas !

As I suspected, it's a configuration problem. As there are only 8
user-defined chars in these displays, Michael decided to have a "Icons"
config option which defines how many chars must be kept for icons, and
the other are used by bars. If you don't set "icons", you don't get
icons ;)

My lcd4linux.conf looks like this :
----------------------------------------------------------------------
display HD44780 {
    driver 'HD44780'
    model 'generic'
    port '/dev/parports/0'
    bits '8'
    size '16x2'
    icons '2'         <----- here's the claim
}
----------------------------------------------------------------------

And here's is the log I get about HD44780 :
----------------------------------------------------------------------
HD44780: controlling 0 GPO's
HD44780: using display with 1 controllers
HD44780: using 8 bit mode
CPU supports Time Stamp Counter
CPU runs at 600.061000 MHz

Hello Xavier !

Hm. I dunno why the Icons Option wasnt in the conf-file anymore.
But now ive managed it. The Icons work fine here how. I didnt
realized that ive to use the Icon-Options in Drivers together
with the Icons itself, thought, that if i put the Icons Option in, that
i get one of hmmm kinda test-icon with that number or so.
Now ive understand and can use it and i find this fascinating. =)

Now i would like to use the scrolling thing. But i dunno where and howto
declare it. Also in the drivers section and just fill more Rows
than my display have? Or in the Layout Section?

Thanks for your fine help.

Regards,
Andreas

If you look at the "Status" file, you can read :
For 0.10.1 :
- add events/input layer
- support "virtual rows" (will be done with events)
