The 600 driver will be registered as character device 10,156, usually 601 under the name '/dev/lcd'. There are a total of 6 supported types : 602 603 0 : do not enable the driver 604 1 : custom configuration and wiring (see further) 605 2 : 2x16 & 2x40 parallel LCD (old wiring) 606 3 : 2x16 serial LCD (KS-0074 based) 607 4 : 2x16 parallel LCD (Hantronix wiring) 608 5 : 2x16 parallel LCD (Nexcom wiring) 609 610 When type '1' is specified, other options will appear to configure 611 more precise aspects (wiring, dimensions, protocol, ...). Please note 612 that those values changed from the 2.4 driver for better consistency. 613 614config PANEL_LCD_HEIGHT 615 depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" 616 int "Number of lines on the LCD (1-2)" 617 range 1 2 618 default 2 619 ---help--- 620 This is the number of visible character lines on the LCD in custom profile. 621 It can either be 1 or 2. 622 623config PANEL_LCD_WIDTH 624 depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" 625 int "Number of characters per line on the LCD (1-40)" 626 range 1 40 627 default 40 628 ---help--- 629 This is the number of characters per line on the LCD in custom profile. 630 Common values are 16,20,24,40. 631 632config PANEL_LCD_BWIDTH 633 depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" 634 int "Internal LCD line width (1-40, 40 by default)" 635 range 1 40 636 default 40 637 ---help--- 638 Most LCDs use a standard controller which supports hardware lines of 40 639 characters, although sometimes only 16, 20 or 24 of them are really wired 640 to the terminal. This results in some non-visible but addressable characters, 641 and is the case for most parallel LCDs. Other LCDs, and some serial ones, 642 however, use the same line width internally as what is visible. The KS0074 643 for example, uses 16 characters per line for 16 visible characters per line. 644 645 This option lets you configure the value used by your LCD in 'custom' profile. 646 If you don't know, put '40' here. 647 648config PANEL_LCD_HWIDTH 649 depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" 650 int "Hardware LCD line width (1-64, 64 by default)" 651 range 1 64 652 default 64 653 ---help--- 654 Most LCDs use a single address bit to differentiate line 0 and line 1. Since 655 some of them need to be able to address 40 chars with the lower bits, they 656 often use the immediately superior power of 2, which is 64, to address the 657 next line. 658 659 If you don't know what your LCD uses, in doubt let 16 here for a 2x16, and 660 64 here for a 2x40. 661 662config PANEL_LCD_CHARSET 663 depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" 664 int "LCD character set (0=normal, 1=KS0074)" 665 range 0 1 666 default 0 667 ---help--- 668 Some controllers such as the KS0074 use a somewhat strange character set 669 where many symbols are at unusual places. The driver knows how to map 670 'standard' ASCII characters to the character sets used by these controllers. 671 Valid values are : 672 673 0 : normal (untranslated) character set 674 1 : KS0074 character set 675 676 If you don't know, use the normal one (0). 677 678config PANEL_LCD_PROTO 679 depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" 680 int "LCD communication mode (0=parallel 8 bits, 1=serial)" 681 range 0 1 682 default 0 683 ---help--- 684 This driver now supports any serial or parallel LCD wired to a parallel 685 port. But before assigning signals, the driver needs to know if it will 686 be driving a serial LCD or a parallel one. Serial LCDs only use 2 wires 687 (SDA/SCL), while parallel ones use 2 or 3 wires for the control signals 688 (E, RS, sometimes RW), and 4 or 8 for the data. Use 0 here for a 8 bits 689 parallel LCD, and 1 for a serial LCD. 690 691config PANEL_LCD_PIN_E 692 depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1" && PANEL_LCD_PROTO="0" 693 int "Parallel port pin number & polarity connected to the LCD E signal (-17...17) " 694 range -17 17 695 default 14 696 ---help--- 697 This describes the number of the parallel port pin to which the LCD 'E' 698 signal has been connected.

This is useful on appliances 788 where a simple 'Starting system' message can be enough to stop a customer 789 from worrying. 790 791 If you say 'Y' here, you'll be able to choose a message yourself.
