(BUSY time depends on contents) Backspace 08H Non destructive backspace. Cursor is moved left by the width of the currently select font. If the cursor is at (50 s) the left end of the display, no cursor movement is made. Horizontal Tab 09H Cursor is moved right by the width of the currently select font. If the cursor is at the end of the display, no (50 s) cursor movement is made. Line Feed 0AH Moves the cursor down by the height of the currently selected font. If the cursor is at the bottom of the (50us) display, no cursor movement is made. Home 0BH Moves the cursor horizontal position to 00H, the vertical positioning is dependent on the currently selected (50us) font, allowing for immediate character writing in the top-left corner of the display. Vertical Tab 0CH Moves the cursor up one character row. If the cursor is at the top of the top end of the display, no cursor (50us) movement is made. Carriage Return 0DH Moves the cursor horizontal position to 00H. The vertical position is unchanged. (50us) Clear EOL 0EH Clear all characters from the current cursor position to the end of the display. (3ms) Test 0FH Place module into self-test mode. The module will repetitively show a few test screens. The test mode will (50 s) exist on the next received byte. Cursor Position 10H + xpos + ypos Set the cursor position. (50us) Set Area 11H + xleft + ytop + xright + ybot Fill specified area. All dots within the specified area are illuminated. Please note that the cursor position is (50us + 2ms last byte ) affected with this command. Clear Area 12H + xleft + ytop + xright + ybot Clear specified area. All dots within the specified area are cleared. Please note that the cursor position is (50us + 2ms last byte ) affected with this command. Invert Area 13H + xleft + ytop + xright + ybot Invert specified area. All dots within the specified area are inverted. Please note that the cursor position is (50us + 2ms last byte ) affected with this command. Set Outline 14H + xleft + ytop + xright + ybot Draw box outline. All dots within the specified outline are unchanged. Please note that the cursor position is (50us + 2ms last byte ) affected with this command. Clear Outline 15H + xleft + ytop + xright + ybot Clear box outline. All dots within the specified outline are unchanged. Please note that the cursor position is (50us + 2ms last byte ) affected with this command. Set Pixel 16H Illuminate a single pixel at the current cursor position. (50us) Clear Pixel 17H Clear a single pixel at the current cursor position. (50us) Graphic Write 18H + len + data Write graphical data, length len, direct to display. See write mode command (1AH) for graphic orientation (50us + 350us each data byte ) and cursor movements. Reset 19H Resets display to power-on defaults: - Display is cleared. 5x7 font selected. Write Mode = 00H (1ms) Brightness Level = 7. VFD Power = On. Write Mode 1AH + data Bit 7 = graphic data orientation - 0 = horizontal, 1 = vertical (default = horizontal) (50us) Bit 6 = cursor movement - 0 = horizontal, 1 = vertical (default = horizontal) Bit 5 = cursor direction - 0 = forward, 1 = backwards (default = forwards) Bit 4 = underscore cursor - 0 = off, 1 = on (default = off) Bit 3 = underscore cursor - 0 = static, 1 = flash (default = static) Bit 1/0 = pen type - 00 = overwrite, 01 = AND, 02 = OR, 03 = XOR (default = overwrite) Set Macro 1BH + macro + len + data Send macro data to EEPROM. macro = 00H - 07H. Macro0 is executed at power-up only. A maximum of 480 (50us 1BH , 10ms macro , 50us bytes is allowed for macro data. The display may flicker whilst writing macro data. len , 5ms data , 20ms last byte ) Brightness 1BH + level Set the display brightness. level = F8H - FFH. F8H = display off. F9H = minimum, FFH = maximum (default). (50us) Erase Macros 1BH + 4DH Clear all downloaded macros in EEPROM. Screen may blank momentarily while macro data is being erased. (100ms) Lock/Unlock EEPROM 1BH + 4CH / 55H All data contained within the non-volatile EEPROM is locked (4CH), and no changes are possible until the (50us + 5ms last byte ) unlock command (55H) is executed. Checksum 1BH + 43H All data received is added to the checksum. This command will read the lower 8-bits of that checksum, (50us) before being cleared. Please note that the checksum is cleared when executing the test mode. Power On/Off 1BH + 50H / 46H 50H = Turn on VFD power supply (default). (50us) 46H = Turn off VFD power supply, displays contents will be preserved. Hex/Binary Mode 1BH + 48H / 42H 48H = Enable hex receive mode, character 60H is interpreted as a hexadecimal prefix. (50us) 42H = Disable hex receive mode. Hex mode is enabled at power up. Set Comms 1BH + 49H + data Set asynchronous communication baud rate and parity. Takes effect at power-up or hardware reset. (50us + 5ms last byte ) Bit 7 = Automatic I/O send (0=off, 1=on). Bits 1&0 = baud rate (00=4800, 01=9600, 02=19200, 03=38400). Bit 2 = Parity (1=even, 0=none) (factory default = 19200 with no parity, automatic I/O send is off) Enable I/O Port 1BH + 44H + data Set I/O port direction. A 1 indicates an input, a 0 an output. All output lines are immediately set low. All (50us + 5ms last byte ) input lines have their pull-ups enabled. This value is store in EEPROM and will automatically be set at power up. Set Port Lines 1BH + 4FH + data Set Output lines on I/O port, a 1 will set 5V on the output ports, or enable the pull-ups on the inputs. (50us) Read Port 1BH + 52H Read current I/O port status. A single byte is transmitted showing the current state of the I/O lines. (50us) Enable Key Scanning 1BH + 4BH Set I/O port to key scanning. The I/O ports are continuously scanned for any key press. This mode is stored (50us + 5ms last byte ) in EEPROM and will automatically be selected at power up. Select Font (50us) 1CH / 1DH / 1EH Select font. 1CH = proportional mini font. 1DH= fixed spaced 5x7 font. 1EH = fixed spaced 10x14 font. Graphic Area Write 1FH + xl + yt + xr + yb + data Write graphic data within defined area. See write mode command (1AH) for graphic orientation and cursor (50us + 350us each data byte ) movements. Note: This command is available on software version 3 only. Hex Prefix 60H + dhH + dlH Write to the display module using a 2-byte hexadecimal number. dhH = high nibble, dlH = low nibble. (50us + 50us + command BUSY) E.g. Sending 19 will reset the display. Character Write (800us) 20H - 7FH Display character from selected font. Notes: - Busy times are not inclusive of a 100us scan period, this must be taken into consideration. If the cursor is enabled, busy times will increase by a further 50us. All coordinates are absolute. The origin (00H, 00H) is the top left of the display. All data shown is in hexadecimal format. NORITAKE ITRON VFD MODULES GU126x64F-K612A4
