//********************************************************************************
//V1.2修改说明
//支持了SPFD5408的驱动,另外把液晶ID直接打印成HEX格式.方便查看LCD驱动IC.
//V1.3
//加入了快速IO的支持
//修改了背光控制的极性（适用于V1.8及以后的开发板版本）
//对于1.8版本之前(不包括1.8)的液晶模块,请修改LCD_Init函数的LCD_LED=1;为LCD_LED=1;
//V1.4
//修改了LCD_ShowChar函数，使用画点功能画字符。
//加入了横竖屏显示的支持
//V1.5 20110730
//1,修改了B505液晶读颜色有误的bug.
//2,修改了快速IO及横竖屏的设置方式.
//V1.6 20111116
//1,加入对LGDP4535液晶的驱动支持
