config PANEL

	tristate "Parallel port LCD/Keypad Panel support"

	depends on PARPORT

	---help---

	  Say Y here if you have an HD44780 or KS-0074 LCD connected to your

	  parallel port. This driver also features 4 and 6-key keypads. The LCD

	  is accessible through the /dev/lcd char device (10, 156), and the

	  keypad through /dev/keypad (10, 185). Both require misc device to be

	  enabled. This code can either be compiled as a module, or linked into

	  the kernel and started at boot. If you don't understand what all this

	  is about, say N.



config PANEL_PARPORT

	int "Default parallel port number (0=LPT1)"

	depends on PANEL

	range 0 255

	default "0"

	---help---

	  This is the index of the parallel port the panel is connected to. One

	  driver instance only supports one parallel port, so if your keypad

	  and LCD are connected to two separate ports, you have to start two

	  modules with different arguments. Numbering starts with '0' for LPT1,

	  and so on.



config PANEL_PROFILE

	int "Default panel profile (0-5, 0=custom)"

	depends on PANEL

	range 0 5

	default "5"

	---help---

	  To ease configuration, the driver supports different configuration

	  profiles for past and recent wirings. These profiles can also be

	  used to define an approximative configuration, completed by a few

	  other options. Here are the profiles :



	    0 = custom (see further)

	    1 = 2x16 parallel LCD, old keypad

	    2 = 2x16 serial LCD (KS-0074), new keypad

	    3 = 2x16 parallel LCD (Hantronix), no keypad

	    4 = 2x16 parallel LCD (Nexcom NSA1045) with Nexcom's keypad

	    5 = 2x40 parallel LCD (old one), with old keypad



	  Custom configurations allow you to define how your display is

	  wired to the parallel port, and how it works. This is only intended

	  for experts.



config PANEL_KEYPAD

	depends on PANEL && PANEL_PROFILE="0"

	int "Keypad type (0=none, 1=old 6 keys, 2=new 6 keys, 3=Nexcom 4 keys)"

	range 0 3

	default 0

	---help---

	  This enables and configures a keypad connected to the parallel port.

	  The keys will be read from character device 10,185. Valid values are :



	    0 : do not enable this driver

	    1 : old 6 keys keypad

	    2 : new 6 keys keypad, as used on the server at www.ant-computing.com

	    3 : Nexcom NSA1045's 4 keys keypad



	  New profiles can be described in the driver source. The driver also

	  supports simultaneous keys pressed when the keypad supports them.



config PANEL_LCD

	depends on PANEL && PANEL_PROFILE="0"

	int "LCD type (0=none, 1=custom, 2=old //, 3=ks0074, 4=hantronix, 5=Nexcom)"

	range 0 5

	default 0

	---help---

	   This enables and configures an LCD connected to the parallel port.

	   The driver includes an interpreter for escape codes starting with

	   '\e[L' which are specific to the LCD, and a few ANSI codes. The

	   driver will be registered as character device 10,156, usually

	   under the name '/dev/lcd'. There are a total of 6 supported types :



	     0 : do not enable the driver

	     1 : custom configuration and wiring (see further)

	     2 : 2x16 & 2x40 parallel LCD (old wiring)

	     3 : 2x16 serial LCD (KS-0074 based)

	     4 : 2x16 parallel LCD (Hantronix wiring)

	     5 : 2x16 parallel LCD (Nexcom wiring)



	   When type '1' is specified, other options will appear to configure

	   more precise aspects (wiring, dimensions, protocol, ...). Please note

	   that those values changed from the 2.4 driver for better consistency.



config PANEL_LCD_HEIGHT

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1"

	int "Number of lines on the LCD (1-2)"

	range 1 2

	default 2

	---help---

	  This is the number of visible character lines on the LCD in custom profile.

	  It can either be 1 or 2.



config PANEL_LCD_WIDTH

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1"

	int "Number of characters per line on the LCD (1-40)"

	range 1 40

	default 40

	---help---

	  This is the number of characters per line on the LCD in custom profile.

	  Common values are 16,20,24,40.



config PANEL_LCD_BWIDTH

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1"

	int "Internal LCD line width (1-40, 40 by default)"

	range 1 40

	default 40

	---help---

	  Most LCDs use a standard controller which supports hardware lines of 40

	  characters, although sometimes only 16, 20 or 24 of them are really wired

	  to the terminal. This results in some non-visible but addressable characters,

	  and is the case for most parallel LCDs. Other LCDs, and some serial ones,

	  however, use the same line width internally as what is visible. The KS0074

	  for example, uses 16 characters per line for 16 visible characters per line.



	  This option lets you configure the value used by your LCD in 'custom' profile.

	  If you don't know, put '40' here.



config PANEL_LCD_HWIDTH

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1"

	int "Hardware LCD line width (1-64, 64 by default)"

	range 1 64

	default 64

	---help---

	  Most LCDs use a single address bit to differentiate line 0 and line 1. Since

	  some of them need to be able to address 40 chars with the lower bits, they

	  often use the immediately superior power of 2, which is 64, to address the

	  next line.



	  If you don't know what your LCD uses, in doubt let 16 here for a 2x16, and

	  64 here for a 2x40.



config PANEL_LCD_CHARSET

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1"

	int "LCD character set (0=normal, 1=KS0074)"

	range 0 1

	default 0

	---help---

	  Some controllers such as the KS0074 use a somewhat strange character set

	  where many symbols are at unusual places. The driver knows how to map

	  'standard' ASCII characters to the character sets used by these controllers.

	  Valid values are :



	     0 : normal (untranslated) character set

	     1 : KS0074 character set



	  If you don't know, use the normal one (0).



config PANEL_LCD_PROTO

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1"

	int "LCD communication mode (0=parallel 8 bits, 1=serial)"

	range 0 1

	default 0

	---help---

	  This driver now supports any serial or parallel LCD wired to a parallel

	  port. But before assigning signals, the driver needs to know if it will

	  be driving a serial LCD or a parallel one. Serial LCDs only use 2 wires

	  (SDA/SCL), while parallel ones use 2 or 3 wires for the control signals

	  (E, RS, sometimes RW), and 4 or 8 for the data. Use 0 here for a 8 bits

	  parallel LCD, and 1 for a serial LCD.



config PANEL_LCD_PIN_E

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" && PANEL_LCD_PROTO="0"

        int "Parallel port pin number & polarity connected to the LCD E signal (-17...17) "

	range -17 17

	default 14

	---help---

	  This describes the number of the parallel port pin to which the LCD 'E'

	  signal has been connected. It can be :



	          0 : no connection (eg: connected to ground)

	      1..17 : directly connected to any of these pins on the DB25 plug

	    -1..-17 : connected to the same pin through an inverter (eg: transistor).



	  Default for the 'E' pin in custom profile is '14' (AUTOFEED).



config PANEL_LCD_PIN_RS

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" && PANEL_LCD_PROTO="0"

        int "Parallel port pin number & polarity connected to the LCD RS signal (-17...17) "

	---help---

	  This describes the number of the parallel port pin to which the LCD 'RS'

	  signal has been connected. It can be :

	      1..17 : directly connected to any of these pins on the DB25 plug

	    -1..-17 : connected to the same pin through an inverter (eg: transistor).



	  Default for the 'RS' pin in custom profile is '17' (SELECT IN).



config PANEL_LCD_PIN_RW

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" && PANEL_LCD_PROTO="0"

        int "Parallel port pin number & polarity connected to the LCD RW signal (-17...17) "

	range -17 17

	default 16

	---help---

	  This describes the number of the parallel port pin to which the LCD 'RW'

	  signal has been connected. It can be :



	          0 : no connection (eg: connected to ground)

	      1..17 : directly connected to any of these pins on the DB25 plug

	    -1..-17 : connected to the same pin through an inverter (eg: transistor).



	  Default for the 'RW' pin in custom profile is '16' (INIT).



config PANEL_LCD_PIN_SCL

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" && PANEL_LCD_PROTO!="0"

        int "Parallel port pin number & polarity connected to the LCD SCL signal (-17...17) "

	range -17 17

	default 1

	---help---

	  This describes the number of the parallel port pin to which the serial

	  LCD 'SCL' signal has been connected. It can be :



	          0 : no connection (eg: connected to ground)

	      1..17 : directly connected to any of these pins on the DB25 plug

	    -1..-17 : connected to the same pin through an inverter (eg: transistor).



	  Default for the 'SCL' pin in custom profile is '1' (STROBE).



config PANEL_LCD_PIN_SDA

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" && PANEL_LCD_PROTO!="0"

        int "Parallel port pin number & polarity connected to the LCD SDA signal (-17...17) "

	range -17 17

	default 2

	---help---

	  This describes the number of the parallel port pin to which the serial

	  LCD 'SDA' signal has been connected. It can be :



	          0 : no connection (eg: connected to ground)

	      1..17 : directly connected to any of these pins on the DB25 plug

	    -1..-17 : connected to the same pin through an inverter (eg: transistor).



	  Default for the 'SDA' pin in custom profile is '2' (D0).



config PANEL_LCD_PIN_BL

	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1"

        int "Parallel port pin number & polarity connected to the LCD backlight signal (-17...17) "

	range -17 17

	default 0

	---help---

	  This describes the number of the parallel port pin to which the LCD 'BL' signal

          has been connected. It can be :



	          0 : no connection (eg: connected to ground)

	      1..17 : directly connected to any of these pins on the DB25 plug

	    -1..-17 : connected to the same pin through an inverter (eg: transistor).



	  Default for the 'BL' pin in custom profile is '0' (uncontrolled).



config PANEL_CHANGE_MESSAGE

	depends on PANEL

	bool "Change LCD initialization message ?"

	default "n"

	---help---

	  This allows you to replace the boot message indicating the kernel version

	  and the driver version with a custom message. This is useful on appliances

	  where a simple 'Starting system' message can be enough to stop a customer

	  from worrying.



	  If you say 'Y' here, you'll be able to choose a message yourself. Otherwise,

	  say 'N' and keep the default message with the version.



config PANEL_BOOT_MESSAGE

	depends on PANEL && PANEL_CHANGE_MESSAGE="y"

	string "New initialization message"

	default ""

	---help---

	  This allows you to replace the boot message indicating the kernel version

	  and the driver version with a custom message. This is useful on appliances

	  where a simple 'Starting system' message can be enough to stop a customer

	  from worrying.



	  An empty message will only clear the display at driver init time. Any other

	  printf()-formatted message is valid with newline and escape codes.
