[lcd4linux] can you please make a lcd4linux conf?

[Koma <ko...@em...>]

Hi i've tried for 4 days to make a .conf file  but the only results i've ha=
ve its a strange symbol repetute.. =20
I put here the wire configuration and the modl of dysplay:

Display "HD44780"
Port "/dev/lp0"
Size "16x2
http://www.camscode.org/images/lcd/th_schaltplan.jpg

if you can reply to me at kom4[=E6]email.it

/dev/lp0 is wrong. Either use /dev/parport0 (or dev/parports/0 with 
devfs) or the hex port adress (e.g. 0x378)

If it still doesn't wortk, I need the whole lcd4linux.conf and the 
output of 'lcd4linux -Fvv'

bye, Michael

look ok to me.

looks fine, too.


Maybe there's a wiring fault, but the picture quality of your schematics 
is too bad:

>>> http://www.camscode.org/images/lcd/th_schaltplan.jpg

I can't read the pin names. Have you got a better image?

Thanks!

Hi everybody,

(sorry Michael, I hit "reply" instead of "reply all" by mistake).

Maybe I'm too old to read the fine-print on the image - but what I _can_ 
read at http://www.camscode.org/images/lcd/th_schaltplan.jpg doesn't 
look like 4-Bit mode to me.

Does setting it to 'Bits "8"' help?

Just a thought

Martin

The language actually wasn't the problem - more the fact that the image 
was so small that it was very hard to read.

Ok, looking at the schematic you sent, your config looks way off. It if 
you wired it like on the schematics (and if I didn't screw up reading 
the schematics), it should look like this:

Port "0x378"
Size "16x2"
Bits "8"
Wire.RW "AUTOFD"
Wire.RS "INIT"
Wire.ENABLE "STROBE"
Wire.ENABLE2 "GND"
Wire.GPO "GND"

I hope that helps
