(0016) *  [使用说明]                                              *
(0017) *              1、需要底层硬件驱动函数支持                 *
(0018) *                 基本的宏定义：                           *
(0019) *                 LCD_RS   LCD_RW   LCD_E                  *
(0020) *                 LCD_SET_WRITE_DATA  LCD_SET_READ_DATA    *
(0021) *                 LCD_SEND_HALF_CHAR_HIGH(a)               *
(0022) *                 LCD_SEND_HALF_CHAR_LOW(a)                *
(0023) *                 当处于串行状态下时，只定义LCD_RS         *
(0024) *                 LCD_E LCD_SEND_HALF_CHAR_HIGH(a)         *
(0025) *                 LCD_SEND_HALF_CHAR_LOW(a)                *
(0026) *              2、如果采用8数据位连接，则需要定义数据端口  *
(0027) *                 LCD_DATA_PORT，同时需要定义宏来开启该功  *
(0028) *                 能：_LCD1602_FULL_DATA_MODEL             *
(0029) *              3、需要修改引用宏定义来指定底层硬件驱动     *
(0030) *                 函数库。                                 *
(0031) *              4、本库驱动下的LCD显示支持1602的各种连      *
(0032) *                 接方法。当使用只写模式是请在引用该头     *
(0033) *                 文件之前加上宏定义：                     *
(0034) *                 # define _USE_LCD_ONLY_WRITE             *
(0035) *              5、在调用本库之前，定义RunStringSpeed可     *
(0036) *                 以设置滚屏的速度。通过在引用前定义       *
(0037) *                 FlashTimeOut 和 FlashGIFTimeOut 可以     *
(0038) *                 改变字符闪烁的频率。                     *
(0039) *              6、增加一个GIF字幕特效函数。                *
(0040) *              7、确定没有LCD复位问题。                    *
(0041) *              8、增加对595串行转并行连接的支持。          *
(0042) *                 需要头文件SerialToCollateral.h           *
