[lcd4linux] Re: [Lcd4linux-devel] unable to compile CVS version

[Xavier V. <xav...@fr...>]

Hello Alex and Barry !

Barry : In fact, the mysql plugin is work in progress and Michael didn't
modify the configuration stuff to make it work, so if you have the mysql
headers installed it will fail. Just do as Alex says for the moment

Yes. I think I've been a little too verbose with this plugin, don't care
about these warnings.
The claim is that by now all 'plugins' and drivers are hard linked into
the lcd4linux executable, but there's no configure switch to choose
which ones to compile.
In the future (after 0.10.0), we'll try to make plugins dynamicaly
loaded, and configure switches to select plugins just as it's possible
for drivers, but wait a little.

Michael : Maybe you should think about this configure switch for 0.10.0
? I'll try to do it myself if I can.

Bye !

[lcd4linux] problems with CrystalFontz 634 v2.0 (CVS Version)

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

Hi, in 0.98, I had to add a 5.0second sleep to the CrystalFontz.c driver.

Otherwise the display never initializes correctly.

In the current CVS version, I've had to do it again.

Line 675:
   // Fixme: why such a large delay?
   usleep(350*1000);
sleep(5); // needed for 634 V2.0

Now it is working.
The scrolling speed is too fast though (for the first line- OS/kernel 
info); it flickers too much to read.

Also, the Curses & PNG displays are missing from the sample config file.

BTW, does anyone have a sample config for showing 3 nics, or 3 nics + total?

Thanks,
Barry Gould

I'm still looking for someone with deep autoconf knowledge :-)

No, I've a better idea:just move this initialisatin stuff into the 
data-fetch function, and execute it on the first call only. This way the 
plugin_init() function does nothing but register the plugin.

Same goes for all other plugins! (Nico? are you listening?)


bye, Michael
