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