Nc = Do Not Connect

The module defaults to an 8 line of 21 character display using the 5x7 font with single pixel spacing. The cursor position auto increments after each character write. The bottom left of a character is placed at the cursor x,y. The M(odule) Busy line indicates the module is busy when high. Connect the H(ost) Busy input to the MBusy to disable handshaking. Use the button to select the configuration, which is then stored in EEPROM. To send commands as hexadecimal, prefix the 2 bytes using character 60H.

Example: `10`3F`01 = Position dot x=64 y=1. To send character 60H to the display, send 60H twice.

NORITAKE ITRON VFD MODULES	GU126x64D-K610A4

	Dot Graphic VFD Module	GU126x64D-K610A4

GU126x64D-K610A4 SETUP

The VFD module features two serial ports (synchronous & asynchronous) and a parallel port, all interfaces are TTL compatible. Interface selection/set-up can be made using the single push button switch on the back of the module. Pressing the switch for the first time will display the initial configuration menu. On each subsequent switch press the menu pointer will advance. The current menu item will be selected if the switch is not pressed within 2 seconds.

To select the required interface, press the switch until the ‘COMMS’ item has been selected.

Wait 2 seconds for the communication menu to be displayed. Press the switch until the required interface is selected. The factory default interface is SPI.

Wait another 2 seconds to display the related communication settings. The current configuration is displayed first.

Interface selection example.

SYNCHRONOUS SERIAL COMMUNICATION

With synchronous communications enabled, data can be clocked into the VFD module using the rising or falling edge of SCK. This is selectable by the push switch on the rear of the module, which also sets the data order. By default, data is clocked in on the rising edge with the most significant bit sent first. The host must provide adequate delays for the module to process the data, these busy times are specified in the software command section. Alternatively the host can monitor the MB (Module Busy) line.

The /SS pin can be used as an enable pin if other devices are connected to the serial line, and also allows byte synchronisation. The use of the /SS line is optional, and can be permanently pulled low if required.

TTL Synchronous serial communication.

ASYNCHRONOUS SERIAL COMMUNICATION

The asynchronous communication speed and parity can be set with the push switch on the rear of the module, or with the ‘UART SETUP’ command. The default settings are 19200 baud with no parity. Again the host most provide adequate delays for the module to process the command and data. The module busy line (MB) will go high when data is currently being processed.

TTL Asynchronous serial communication from VFD module to host system.

The 8 I/O lines can be configured as a slow parallel interface. Data on PA0-7 is clocked into the module with the Enable line, this can be set to either a rising or falling edge trigger by the push switch on the back of the module. The host must keep the data stable for the time period indicated in the timing diagram. The module busy line (MB) can be used in parallel communication mode.
