SERIAL_LCDGT Data sheetUniversal controller of Graphic LCD screen3 TEXT and GRAPHIC ScreensThe LCD screen compatible with the SLCDGT must integrate a controller of the T6963C type. This lastmanage a SRAM memory of 64 Ko maximum. Just like the T6963C, it is integrated into the LCD and itcontains the data to be displayed.All the data safeguarded in a SRAM zone, are lost in absence of power supply.This memory is divided into 3 zones: the zone(s) of TEXTE screen(s), the zone(s) of GRAPHIC screen(s)and the TEXT Font zone.The variables « text_home », « graph_home » and « cgram_home » determine the beginning of the zonesinto SRAM ( see « CONFIG_SLCDGT » register ).According to the size of the SRAM, it is possible to define several TEXT screens and/or several GRAPHscreens in definite SRAM zones.The SLCDGT manage 2 address pointers who determine the beginning of the TEXT and GRAPH screensdisplayed on the LCD : « PTR_ECRAN_TEXT » and « PTR_ECRAN_GRAPH ». By modifying these pointers, itis possible to switch from a screen to another.The 2 TEXT and GRAPH screens can be independently lit, extinguished or be combined.The TEXT screen is addressable by characters while the GRAPHIC screen is addressable pixel by pixel.CGRAM Zone : Its size is fixed at 256 * 8 bytes = $0800.TEXT Screen Zone : Its size is a multiple of NBRE_CAR x NBRE_LIGNE.GRAPH Screen Zone : Its size is a multiple of NBRE_PIXELH x NBRE_PIXELV.The « cgram_home » zone beginobligatorily at a multiple address of$0800 :SRAM LCD Size Up to 8Ko Up to 32Ko Up to 64KoCgram_homepossible$0000 – $07FF$0800 – $0FFF$1000 – $17FF$0000 – $07FF$0800 – $0FFF$1000 – $17FF...$E000 – $E7FF$E800 – $EFFF$0000 – $07FF$0800 – $0FFF$1000 – $17FF...$E000 – $E7FF$E800 – $EFFF$F000 – $F7FF$F800 – $FFFFThe screens displayed on the LCD depend on the value of "PTR_ECRAN_TEXT" and "PTR_ECRAN_GRAPH"pointers.SRAMLCD8Ko$2000text_home = $0000$0000zone plan TEXT$077F40x16=x0280 bytescgram_home = $0800graph_home = $1000$1000zone plan GRAPH$1EFF240x128=x0F00 bytes$0000$0280$0500$0780$0800$0900$1000$1F00freefreefree$027F$04FF$077F$07FF$08FF$0FFF$1EFF$1FFFECRANT(0)ECRANT(1)ECRANT(2)CGRAMECRANG(0)LCD 240x128avec 8Ko SRAMTo display on the LCD the TEXT(1) screencontents in SRAM, PTR_ECRAN_TEXT mustbe set with $0280The zone from $0800 to $08FF is reservedfor the redefined TEXT characters (CGRAM).To display on the LCD the GRAPHIC(0)screen contents in SRAM,PTR_ECRAN_GRAPH must be set with $1000SERIAL_LCDGT Specifications Version 1.1 - Juin 2006 Page 12 of 37Last printed 03/06/2006 12:37

SERIAL_LCDGT Data sheetUniversal controller of Graphic LCD screen3.1 TEXT ScreenA text screen consists of ASCII characters. They can come from the internal ASCII table of the T6963Ccontroller or from a table of characters created by the user. What under hears that even on the TEXTscreen, the screen can manage a minimum of graphs (in the form of redefined characters).The size of the text screen is defined by the following parameters:• NBRE_PIXELH : 0

SERIAL_LCDGT Data sheetUniversal controller of Graphic LCD screen3.2 GRAPHIC ScreenThese screens consist of pixels. The maximum definition that the SERIAL_LCDGT can manage is 240x128pixels (limitation of the T6963C in « SINGLE-SCREEN » mode). The SLCDGT can manage all the inferiorsizes.A graphic screen is made up of images directly provided to the SLCDGT, or of graphs drawn by the SLCDGTaccording to commands received from the MASTER.The SLCDGT allows in addition to manage graphical Fonts and Icons.3.2.1 ICONS ManagementThe SLCDGT makes it possible to manage 4 formats of icons : 8x8, 8x16, 16x8 et 16x16 pixels. These iconscan be displayed at any co-ordinates by specifying their higher left corners.The icons are available only if the EEPROM option (– ME OPTION ) is wired on the SLCDGT.Type 0 : 8x8Type 2 : 16x8Type 1 : 8x16Type 3 : 16x163.2.2 Graphic FONTS ManagementThe SLCDGT makes it possible to manage graphic fonts. A character of the graphic font consists of 8x8pixels. These characters support the x2, x3 and x4 ZOOM function and can be displayed at any co-ordinatesby specifying their higher left corners.A font can comprise up to 256 characters of 8x8 pixels. Several font can be declared into EEPROM.The graphic fonts are available only if the EEPROM option (- ME OPTION ) is wired on the SLCDGT.SERIAL_LCDGT Specifications Version 1.1 - Juin 2006 Page 14 of 37Last printed 03/06/2006 12:37

SERIAL_LCDGT Data sheetUniversal controller of Graphic LCD screen5 InstructionsAll the functions require an execution time during which the SLCDGT is unavailable. This time depends onthe size of the task to realize (To trace a circle of radius of 10 pixels is faster than one of radius of 50pixels) and of the LCD size(More faster to delete a 64 x 64 LCD dot than a 240 x 128 LCD dot).5.1 Global Instructions Set ( $00 - $3F )5.1.1 $00 : Reading Version registerCommand$00Reading the version number of the software.Remarks :- The response time at a reading request is skeletal (see command $3F: "CONFIG_SLCDG").- When the I2C mode is selected, after the reading command "ADRM, $00" it is necessary tomake a reading at the address "ADRM + 1" to obtain the data.User Note :5.1.2 $01 : "SET MODE" register ManagementCommand Attribut1$01 NThis command makes it possible to define the operating mode desired between the TEXT plans andGRAPHIC plans as well as the mode of use of the characters generator ( CG mode ).The T6963C can operate according 2 display modes :• TEXTE mode and/or GRAPHIC mode :The two plans can be combined following the logical manners: AND, OR or EXOR.The plans can be managed in an independent way.• TEXT_ATTRIBUT mode : This mode is a TEXT mode whose each character can have differentspecificities of display.
