建议一般在试验时候，如果没有把握，尽量不要去修改源程序，这样很难判断是程序问题还是连接问题，下面这个程序可以再试试。

用这个程序只能显示红色或者绿色，如果可以正常显示，再给你找找显示双色，一步一步来了。

P1_4=1;//消影。------OE。
P1_7= 1;   // 点亮屏幕------STR.
P1=tab[disrow];   -------P10，P11，P12，P13连接A,B,C,D。                                             
P3_1=1;      //(CLK=P3_1)上升沿595输出 --------CLK
P3_0；-------R或者G。

    【接R口的时候下半屏全亮 上半屏能显示流动的字】
1】因为这个是16X64的程序，你的屏是32X64，所以接R口的时候下半屏全亮，你要把下半屏的R和G接地或者接VCC+5V，试试是不是可以解决。

【接G口的时候 下半屏全亮 但是上半屏闪烁 而且没有感到有绿颜色】
2】和上面一样试试，上半屏闪烁，因为是绿色显示，晶体必须是24M，如果用STC芯片，用6T下载，效果还要好。

3】如果要同时上下屏一起试验，可以把上屏的R  的最后一个595的9脚，和G的最后一个595的9脚，分别连接到输入接口的下屏R和G端口。

4】程序因为是单色显示程序，所以在显示时候，如果用R时候，G必须接地或者接VCC+5V，显示G时候，R必须接地或者接VCC+5V。

我将上面老师给的程序改咯下 改成从右往左移动  字就出现错位 这个是怎么回事呢
还有这句8字是for(s=17+inc;s>=0+inc;s--)
  s的取值我还是没有搞好清楚  这里的8字是指要显示的字为八个么

【这一段空白代码什么作用，一定要么？】主要是考虑屏上电后，有4个字的不显示区，如果不要，上电就在左面开始直接显示了。
