503	---help---
504	  Say Y here if you have an HD44780 or KS-0074 LCD connected to your
505	  parallel port. This driver also features 4 and 6-key keypads. The LCD
506	  is accessible through the /dev/lcd char device (10, 156), and the
507	  keypad through /dev/keypad (10, 185). Both require misc device to be
508	  enabled. This code can either be compiled as a module, or linked into
509	  the kernel and started at boot. If you don't understand what all this
510	  is about, say N.

516	default "0"
517	---help---
518	  This is the index of the parallel port the panel is connected to. One
519	  driver instance only supports one parallel port, so if your keypad
520	  and LCD are connected to two separate ports, you have to start two
521	  modules with different arguments. Numbering starts with '0' for LPT1,
522	  and so on.

529	---help---
530	  To ease configuration, the driver supports different configuration
531	  profiles for past and recent wirings. These profiles can also be
532	  used to define an approximative configuration, completed by a few
533	  other options. Here are the profiles :
534
535	    0 = custom (see further)
536	    1 = 2x16 parallel LCD, old keypad
537	    2 = 2x16 serial LCD (KS-0074), new keypad
538	    3 = 2x16 parallel LCD (Hantronix), no keypad
539	    4 = 2x16 parallel LCD (Nexcom NSA1045) with Nexcom's keypad
540	    5 = 2x40 parallel LCD (old one), with old keypad
541
542	  Custom configurations allow you to define how your display is
543	  wired to the parallel port, and how it works. This is only intended
544	  for experts.

552	  This enables and configures a keypad connected to the parallel port.
553	  The keys will be read from character device 10,185. Valid values are :
554
555	    0 : do not enable this driver
556	    1 : old 6 keys keypad
557	    2 : new 6 keys keypad, as used on the server at www.ant-computing.com
558	    3 : Nexcom NSA1045's 4 keys keypad
559
560	  New profiles can be described in the driver source. The driver also
561	  supports simultaneous keys pressed when the keypad supports them.

569	   This enables and configures an LCD connected to the parallel port.
570	   The driver includes an interpreter for escape codes starting with
571	   '\e[L' which are specific to the LCD, and a few ANSI codes. The
572	   driver will be registered as character device 10,156, usually
573	   under the name '/dev/lcd'. There are a total of 6 supported types :
574
575	     0 : do not enable the driver
576	     1 : custom configuration and wiring (see further)
577	     2 : 2x16 & 2x40 parallel LCD (old wiring)
578	     3 : 2x16 serial LCD (KS-0074 based)
579	     4 : 2x16 parallel LCD (Hantronix wiring)
580	     5 : 2x16 parallel LCD (Nexcom wiring)
581
582	   When type '1' is specified, other options will appear to configure
583	   more precise aspects (wiring, dimensions, protocol, ...). Please note
584	   that those values changed from the 2.4 driver for better consistency.

607	range 1 40
608	default 40
609	---help---
610	  Most LCDs use a standard controller which supports hardware lines of 40
611	  characters, although sometimes only 16, 20 or 24 of them are really wired
612	  to the terminal. This results in some non-visible but addressable characters,
613	  and is the case for most parallel LCDs. Other LCDs, and some serial ones,
614	  however, use the same line width internally as what is visible. The KS0074
615	  for example, uses 16 characters per line for 16 visible characters per line.
616
617	  This option lets you configure the value used by your LCD in 'custom' profile.
618	  If you don't know, put '40' here.
619
620config PANEL_LCD_HWIDTH

623	range 1 64
624	default 64
625	---help---
626	  Most LCDs use a single address bit to differentiate line 0 and line 1. Since
627	  some of them need to be able to address 40 chars with the lower bits, they
628	  often use the immediately superior power of 2, which is 64, to address the
629	  next line.
630
631	  If you don't know what your LCD uses, in doubt let 16 here for a 2x16, and
632	  64 here for a 2x40.

639	---help---
640	  Some controllers such as the KS0074 use a somewhat strange character set
641	  where many symbols are at unusual places. The driver knows how to map
642	  'standard' ASCII characters to the character sets used by these controllers.
643	  Valid values are :
644
645	     0 : normal (untranslated) character set
646	     1 : KS0074 character set
647

655	---help---
656	  This driver now supports any serial or parallel LCD wired to a parallel
657	  port. But before assigning signals, the driver needs to know if it will
658	  be driving a serial LCD or a parallel one. Serial LCDs only use 2 wires
659	  (SDA/SCL), while parallel ones use 2 or 3 wires for the control signals
660	  (E, RS, sometimes RW), and 4 or 8 for the data. Use 0 here for a 8 bits
661	  parallel LCD, and 1 for a serial LCD.
