This is a "plugin" for the Video Disk Recorder (VDR).

Description: Output to LCD modules that are supported by LCDproc
-------------------------------------------------------------------------
vdr -Plcdproc or -P"lcdproc -h <host> -p <port>" ... makes vdr connect to a LCDd.
Current channel info and menus are then displayed on the LCD too.
I had a 4x20 character display in mind but it should
work with 4x16 up to 4x40.
LCDd can be used in an xterm or console too, so it
might be useful even without having the hardware.
( ./LCDd -d curses )
lcdtranstbl-xxx.h is used to map characters for output to LCDd.
Depending on the LCD hardware some characters may not displayed
correctly, you can fix that by altering this table ...
use lcdtranstbl-nomap.h if you don't want anything mapped.
what table is used can be selected at compile time:
e.g. ... LCDTRANS=CFontz make plugins ...
values for LCDTRANS are 'hd44780', 'CFontz' and 'nomap' ('hd44780' is the default value).
Thanks to Stephan Schreiber <stephan@sschreiber.de> for lcdtranstbl-CFontz.h.
LCDproc is available at http://lcdproc.omnipotent.net/
or here http://sourceforge.net/projects/lcdproc/
What's needed to run a LCD?
Hardware:
I used a single 4x20 LCD that works with the hd44780 8-bit driver on
the printer port.
( availible at http://www.conrad.com/ product ID: 187275
or see http://www.lcd-module.de/eng/doma/standard.htm )
printer port LCD
----------------------------------------------------------------------
GND (1) (used the PC's power suppy (black cable))
+5V (2) (used the PC's power suppy (red cable))
Vadj (3) (contrast, conneced to GND works fine for me)
D0 (2) D0 (7)
D1 (3) D1 (8)
D2 (4) D2 (9)
D3 (5) D3 (10)
D4 (6) D4 (11)
D5 (7) D5 (12)
D6 (8) D6 (13)
D7 (9) D7 (14)
nSTRB (1) EN (6)
INIT (16) RS (4)
RW (5) (connected to GND (1) of the LCD)
GND (18-25)
--- optional for LCDs with background illumination ---
LED+ (15) (connected to +5V over a 100Ohm resisitor
to make it not too bright)
LED- (16) (connected to GND)
Software:
Last tested with lcdproc-0.4.1 ( http://prdownloads.sourceforge.net/lcdproc/lcdproc-0.4.1.tar.gz )
LCDd -d HD44780 "-p 0x3bc -c winamp"
should run LCDd for the hardware described above conneceted to the
printer port (in my case the port's base address is 0x3bc).
