//液晶字符、汉字输出
//液晶显示基本函数
/***********************************************************************
公司名称:  泰克通信
模 块 名： 液晶显示字符、汉字输出           LCD 型号：NHC-01 
创 建 人：        输入输出模块组            日期：2004-03-17
修 改 人：        输入输出模块组            日期：2004-03-23 
功能描述： 1、输出汉字
           2、输出英文字符、数字
           3、输出字符串，可以包含数字及几个标点
其他说明： 本程序在atmag128和nhc-01上调试通过
