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 and 2x40.
2x16+ displays should work too but are NOT fully supported.
LCDd can be used in an xterm or console too, so it
might be useful even without having the hardware.
( ./LCDd -d curses )
lcdtranstbl.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 selecting a in the setup menu: (Charmap)
0 ... nomap no mapping, useful for the curses driver
1 ... hd44780
2 ... CFontz Thanks to Stephan Schreiber <stephan@sschreiber.de>
lcdkeyconf.h is used to configure the plugin for a keypad.
you can use a different file instead with
LCDKEYCONF=/path/to/your/lcdkeyconf.h
during compile time.
Mattia Rossi <mattia@technologist.com> added support for the output pins
that some Matrix Orbital displays have (lcdm001 and glk driver).
So the card status among other things can be indecated by led.
Brief description of the setup menue:
FullCycle / TimeDateCycle
during recording the some displays toggle between time/date and card status
FullCycle (seconds) is the time for a complete cycle while
TimeDateCycle (seconds) is the duration where time/date is shown.
VolumeKeep
( 1/10 seconds ) how long the volume is shown on the display
Scrollwait
( 1/8 seconds ) duration before scrolling is started
Scrollspeed
( 1/8 seconds ) higher value means slower scrolling
Charmap
see above.
AltShift
when a keypad is used and a shiftkey is defined the type of shiftkey
indication ( done by LCDproc's 'heartbeat' ) can be changed.
BackLight
backlight on/off
OutputNumber
implemented by Mattia Rossi <mattia@technologist.com>
sets how many output pins should be used to indicate
states like on/off, card status, ...
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).
