lcd320.c

在移植成功ucos核的基础上扩充了该操作系统的许多没有功能。如文件系统

/*----------------------------------------------------------------------------------
    #说明: 液晶屏驱动程序for uCos-II
    #接口函数
		void LCD_Cls(); //文本模式下清除屏幕?
		void LCD_ChangeMode(U8 mode);
		void LCD_Refresh();

		void LCD_Init();
		void LCD_printf(const char *format,...);

		void LCDBkLight(U8 isOpen);
		void LCDDisplayOpen(U8 isOpen);
		void LCD_TestShow();
	----------------------------------  Bug  --------------------------------------

	----------------------------------  TODO list  --------------------------------------

	----------------------------------修正--------------------------------------
	2003-11-21	添加了640x480 LCD驱动程序，定义了LCDTYPE_640x480x256STN类型
				修正了LCD_ReFresh中超范围的bug
	2003-10-9	在LCD320.h中添加定义LCDTYPE，来控制LCD类型。整合了
				320x240 16级灰度的液晶屏和320x240 256色的液晶屏驱动程序
    2004-4-15   修正了文本输出的一些BUG，比如原来只能整行输出,滚屏错乱等
