DS1302与LCD之间如何数据传输，函数调用？

我的ＬＣＤ经过我的一番努力终于能调出显示啦！可是我的DS1302和LCD之间的数据传输，函数调用却出了问题！我现在就不懂ＬＣＤ怎样才能读出ＤＳ１３０２的时钟数据？我的ＬＣＤ是用并口的！请高手出招！！！！！！

7个数据都读出来了，先看RAM中对否，对了
就查表送数据显示啊

你这几天留意下我的blog吧，我会将整个测试程序发在我的BLOG上。
有LCD1602、DS18B20、DS1302、240x、UART、KEY、ADC0832等等驱动~~~~

DS1302驱动程序->接口数据->数据转换为字符串->调用LCD驱动程序显示

简单的LCD驱动程序：
一般包含：
  MoveTo(x,y)移动到指定位置
  DisplayStr(char *str)在当前位置显示字符串
  DisplayStr内部又调用更低层的DisplayChar( char c );

DisplayChar( char c )实现又需要字模数据：一个2维数组Font[windth][height]。Font[windth]中每BIT代表一个象素点，一个字节代表8个点，12点宽度的话，高字节的高4位无效，一般=0。
  程序中依靠宽度、高度写进LCD中象素位置，

  完成。

请问那DS1302已经启动，且读出的时钟数据正常，但我希望在半途中改变现有时间，比如用按键1，每按一下键位，那分钟位就上调一分钟，那该怎么去弄程序？？？
