If the cursor is at the left end of the display the cursor moves to the right end 6us of the line above. If the cursor is at the left end of the top line no cursor movement is made. Horizontal Tab 09H Moves the cursor right by one character. If the cursor is at the right end of the display the cursor moves to the left end 6us (40us on scroll) of the line below. If the cursor is at the right end of the bottom line the action depends on the write mode currently selected. In DC1 mode the cursor moves to the left end of the top line. In DC2 mode the entire display contents is scrolled up by one line, the bottom line is cleared and the cursor moves to the left end of the bottom line. Line Feed 0AH Moves the cursor down by one line. If the cursor is at the bottom of the display the action depends on the write mode 6us (40us on scroll) currently selected. In DC1 mode the cursor moves to the top line. In DC2 mode the entire contents of the display is scrolled up by one line and no cursor movement is made. Form Feed 0CH Moves the cursor to the top left end of the display. 6us Carriage Return 0DH Moves the cursor to the left end of the current line. 6us Clear 0EH Clear all displayed characters. No cursor movement is made. 65us Overwrite mode (DC1) 11H Specifies character overwrite mode. (default) 6us Vertical scroll mode (DC2) 12H Specifies vertical scroll mode. 6us Cursor off (DC4) 14H No cursor is displayed. (default) 6us Cursor on (DC5) 15H A blinking full block is displayed at the cursor position. The blink rate can be specified using the Blink Speed Control 6us command. Cursor off (DC6) 16H No cursor is displayed. 6us Cursor off (DC7) 17H No cursor is displayed. 6us International Font 18H All subsequent characters displayed will be from the International font. This font can also be selected as the default by 6us using the JA hardware jumper link (OPEN). KATAKANA Font 19H All subsequent character displayed will be from the KATAKANA font. This font can also be selected as the default by 6us using the JA hardware jumper link (LINKED). Euro Symbol 1AH This command enables the Euro currency mark at location ADH in the International font. Sending the International 7us (40us on scroll) Font command (or after a reset) restores the character at location ADH to a blank (this is the default condition). This will affect any existing ADH characters already on the display. User Defined Font 1BH Define a user character. Up to 16 user characters can be defined and stored by 6us (1BH) + 43H the module. The specified character code can be 00H – FFH. Command codes 4us (43H) Dot assignment + character code can be overwritten with a UDF so be aware that doing so will disable that 6us (byte 1) 6us (byte 2) + data byte 1 command. All UDF’s are lost on power off or reset. If more that 16 UDF’s are P1 P2 P3 P4 P5 6us (byte 3) + data byte 2 defined the older definitions are overwritten. 6us (byte 4) 15us (byte 5) + data byte 3 P6 P7 P8 P9 P10 Bit / Byte assignment + data byte 4 P11 P12 P13 P14 P15 + data byte 5 7 6 5 4 3 2 1 0 Byte 1 P8 P7 P6 P5 P4 P3 P2 P1 P16 P17 P18 P19 P20 Byte 2 P16 P15 P14 P13 P12 P11 P10 P9 P21 P22 P23 P24 P25 Byte 3 P24 P23 P22 P21 P20 P19 P18 P17 P26 P27 P28 P29 P30 Byte 4 P32 P31 P30 P29 P28 P27 P26 P25 P31 P32 P33 P34 P35 Byte 5 - - - - - P35P34P33 Cursor Moving 1BH The cursor is moved to the specified position. The relationship between the position value and the display is as 6us (1BH) + 48H follows:- 4us (48H) nd rd + position 4us (position) Left end 2 col 3 col - Right end Top 00H 01H 02H - 13H nd 2 row 14H 15H 16H - 27H rd 3 row 28H 29H 2AH - 3BH Bottom 3CH 3DH 3EH - 4FH Luminance 1BH The display luminance can be set to one of 4 levels. 6us (1BH) + 4CH luminance = 00H – 3FH specifies 25% 4us (4CH) + luminance luminance = 40H – 7FH specifies 50% 4us (luminance) luminance = 80H – BFH specifies 75% luminance = C0H – FFH specifies 100% (default) Flickerless Writing Mode 1BH Set flickerless write mode. By default, priority is given to data communication and display flicker can occur if data is 6us (1BH) + 53H sent to the display continuously. If flickerless writing mode is specified, priority is given to display refresh to avoid 6us (53H) possible flicker. Command and data busy times will be up to 200us longer when this mode is set. Blink Speed Control 1BH The blink rate of the cursor can be specified. Rate = speed x 30ms. (default=14H) 6us (1BH) + 54H 4us (54H) + speed 6us (speed) Initialise 1BH Clear the display, erase any defined characters, set the cursor position to the top left of the display and reset all 6us (1BH) + 49H settings to defaults. 65us (49H) Character Write 20H – FFH Display the specified character from the currently selected font (or UDF is defined) at the current cursor position. After 7us (40us on scroll) the character is written to the display a horizontal tab automatically follows. NORITAKE ITRON VFD MODULES CU20049-KTW220A
