Each bit in byte n corresponds to a particular setting as follows:- (BUSY = 350us) Bit 1 Set font 0 = 5x7 , 1 = 10x14 Bit 2 Font mode 0 = Normal , 1 = Inverse Bit 3 Cursor position 0 = Increment , 1 = Decrement Bit 4 Cursor move 0 = Horizontal , 1 = Vertical Bit 5 Graphic write 0 = Horizontal , 1 = Vertical Bit 6,7 Write mode 00 = Overwrite , 01 = AND , 10 = OR , 11 = XOR (The power-on default display mode is 00H). XON 11H Asynchronous serial transmit enable (default). Ignored if using hardware handshaking, or synchronous serial communications. Set I/O C3-C0 12H + 43H + n Set port direction for user I/O lines C3C0. 0=Output, 1=Input. (Bits 4 to 7 are ignored). (BUSY = 350us, 4ms last byte ) This setting is stored in EEPROM. Factory default is all inputs. Set I/O D7-D0 12H + 44H + n Set port direction for user I/O lines D7D0. 0=Output, 1=Input. (BUSY = 350us, 4ms last byte ) This setting is stored in EEPROM. Factory default is all inputs. Key Scan Mode 12H + 46H Key scan enable. Key codes are automatically sent to the asynchronous serial port. (BUSY = 350us, 4ms last byte ) Key codes are in the form of: - 4BH + n1H + n2H (n1H = C3-C0, n2H = D7-D0) This mode is stored in EEPROM. I/O Mode 12H + 47H Disable key scanning and enable general I/O control. (BUSY = 350us, 4ms last byte ) This mode is stored in EEPROM. This mode is the factory default. Read Key 12H + 48H Poll keyboard. Returns current key status. (BUSY = 350us) Key codes are in the form of: - 4BH + n1H + n2H (n1H = C3-C0, n2H = D7-D0) Read Inputs D7-D0 12H + 54H Request to read data from user I/O lines D7 D0. (BUSY = 350us) Responds with:- 52H + nnH (nnH = D7-D0 pin status) Read Inputs C3-C0 12H + 55H Request to read data from user I/O lines C3 C0. (BUSY = 350us) Responds with:- 52H + nnH (nnH = C3-C0 pin status) Set RS232 12H + 59H + n Set baud rate and parity. Settings are stored in EEPROM and only take effect at power up. (BUSY = 350us, 4ms last byte ) Baud Rate Bit 6 Bit 5 Bit 4 Parity Bit 3 Bit 2 Handshaking Bit 0 2400 0 1 0 NONE 0 0 Hardware 0 4800 0 1 1 ODD 0 1 Software 1 9600 1 0 0 EVEN 1 1 1440 1 0 1 19200 1 1 0 38400 1 1 1 XOFF 13H Asynchronous serial transmit disable. Ignored if using hardware handshaking, or synchronous serial communications. Active Area 14H + left + top + right + Set active area. This defines the area in which all subsequent character and graphic writes (BUSY = 350us) bottom occur. Current writing (cursor) position is always relative to the top left of the active area (0,0). Any data written that exceeds the active area is not displayed. (The default is set to full display area). Cursor Position 15H + xpos + ypos Position cursor. Sets the writing position within the current active area. (default is 0,0) (BUSY = 350us) Luminance 16H + n Set luminance. Set one of 32 levels of brightness. (BUSY = 350us) 00H Display off 01H Lowest brightness 1FH Highest brightness (default) Invert 17H Active area invert. Note: Display mode has no effect on this command. (BUSY = 800us) Fill 18H Active area fill. Note: Display mode has no effect on this command. (BUSY = 800us) Outline 19H Draw box outline around active area. Note: Display mode has no effect on this command. (BUSY = 900us) Graphic Write 1AH + len + data Write graphic bytes. The format in which each byte is written and the action of the writing (BUSY = 350us, 500us data ) position between bytes is determined by values set using the set display mode command. len = number of graphical bytes to write. Reset 1BH + 00H Clear display and reset all settings to default values. (BUSY = 700us) PSU Off 1BH + 01H Switch internal PSU off. Display data is retained. (BUSY = 350us) PSU On 1BH + 02H Switch internal PSU on. (Default) (BUSY = 350us) Set Outputs D7-D0 1BH + 03H + n Writes data byte n to user I/O ports D7D0. (BUSY = 350us) Set Outputs C3-C0 1BH + 04H + n Writes data byte n to user I/O ports C3C0. (Bits 4-7 are ignored). (BUSY = 350us) RS232 Out 1BH + 05H + n + 00H + Directs data byte n from synchronous serial port to asynchronous serial port. A status byte is th (BUSY = 350us) 00H return on the 5 byte (00H). Returned status byte: - 53H successful 46H failed. Character Write 20H 7FH Write ASCII characters. (BUSY = 600us) Jumper links : SPI enable link JP5. NORITAKE ITRON VFD MODULES GU128x18F-K612A2
