Hello,

is it possible, to run a LCD 40x4 with HD44780 (Samsung chip) and winamp 
wiring with a backlight switch? The wiring uses pin 17 for EN2 which is also 
used for backlight.

hd44780-winamp.c:
...
|* Backlight
|* SEL  (17)      backlight (optional, see documentation)

I've tried to change the backlight pin to number 14, 'cause i don't use nRW 
at the LCD (it's grounded).

         p->backlight_bit = (state?0:nLF);

but that doesn't work. ;) I must say, that i'm not a coder...

I'm using lcdproc-0.5.2.

Any hints?
