[lcd4linux] display problems with CF634 v2.0 in 0.10.1 RC2

[Barry G. <mai...@pe...>]

Hi, I have been running 0.10.0 for a couple of years with my CF634 
v2.0 quite happily.

However, I recently tried 0.10.1 RC2, and I am having problems with 
the display being almost unreadable.

I had problems before (with 0.10.0) in that the v2.0 634 needs a 
5-second delay during initialization; I'm not sure if this is the 
same problem or not.
Did the delay paramater/option ever get added into the code?
(emails from Herbert Rosmanith quoted below)

It is as if the contrast is WAY off, and it is only slightly readable 
at a large angle away from directly facing the LCD.

configuration:
Display CF634 {
     #Icons 1
     Driver 'Crystalfontz'
     Model '634'
     Port '/dev/ttyS1'
     Speed 19200
     Contrast 16
     Backlight 100
     Size '20x4'
}


output of 0.10.1 RC2:

# ./lcd4linux -Fv -f lcd4linux.conf
Version 0.10.1-RC2-796 starting
[KVV] Using station 89
[KVV] Using default port 80
[KVV] Using default refresh interval of 60 seconds

Crystalfontz: using model '634'
Crystalfontz: using port '/dev/ttyS1' at 19200 baud

BTW, the cf634 is missing from the sample config file in 0.10.1 RC2.


Thanks!
