Re: [Lcd4linux-devel] Treiber einbinden

Hi Til,

you probably want to subscribe to the (low traffic) lcd4linux mailing lists, otherwise I have to manually accept every 
mail from you to go to the list....

Send me the driver file itself and the output of "svn diff" as described in the "How to write a new driver"

Yes please, add a page in the wiki.

Patches are always welcome!

This has been discussed for ages, there is already some basic functionality in there, but I never had the time to finish it.

As you may have noticed, development and especially releasing is very very slow. The "latest news" on the wiki reads 
"new version soon to be released", a whole year passed by, and nothing happens. This is my fault, because I'm extremly 
busy at my real-life job for more than two years now (you know, I get up between 2 and 3 am every day, which means 
really "every day").

Yes, this is by design. When the string changes, also the string length may change, so that the Marquee Scrolling may no 
longer be necessary (or scrolling may get confused because we're on a scroll position where the new string is completely 
empty).

Maybe we should change the behaviour to reset scrolling only if the length changes?




bye, Michael
