(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. */ /* * * exported fuctions: * * struct DRIVER drv_Noritake * */ #include "config.h" #include #include #include #include "debug.h" #include "cfg.h" #include "qprintf.h" #include "plugin.h" #include "widget.h" #include "widget_text.h" #include "widget_icon.h" #include "widget_bar.h" #include "drv.h" #include "udelay.h" #include "drv_generic_text.h" #include "drv_generic_parport.h" static char Name[] = "Noritake"; typedef struct { int type; char *name; int rows; int cols; int xres; int yrex; int goto_cost; int protocol; } MODEL; static int Model, Protocol; static MODEL Models[] = { {0x01, "GU311", 4, 21, 6, 8, 5, 1}, {0x02, "GU311_Graphic", 4, 21, 6, 8, 6, 1}, {0xff, "Unknown", -1, -1, -1, -1, -1, -1} }; static unsigned char SIGNAL_CS; /* Chip select, OUTPUT, negative logic, pport AUTOFEED */ static unsigned char SIGNAL_WR; /* Write OUTPUT, negative logic, pport STOBE */ static unsigned char SIGNAL_RESET; /* Reset, OUTPUT, negative
