+ * *** Noritake Itron GU128x32-311 ***
+ * A 128x32 VFD (Vacuum Fluorescent Display).
+ * It is driver by a Hitachi microcontroller, with a specific

+ * The datasheet can be easily found on the internet by searching for the
+ * the name of the display, it's a PDF file that describe the timing, and
+ * the protocol to communicate with the Hitachi microcontroller.
+ *
+ * The display support 2 modes (that can be mutiplexed), one text mode
+ * thanks to an integrated character generator, and provide 4 lines of
+ * 21 caracters.
+ * There is also a graphical mode that can be used to switch on or off
+ * each one if the 128x32 pixels. (monochrome).
+ *
+ * The protocol include the possibility to clear the display memory quickly,
+ * change the luminosity, swich the display on or off (without affecting the
+ * content of the memory) and finally change the "page" or the caracter
+ * generator. Two pages are available in the ROM, all the characters are
+ * listed in the documentation.
+ *
+ * This driver support only the character mode at the moment.
+ * A future release will support the graphical mode as an option.
+ *
+ * This driver is released under the GPL.
