1、595，他是移位寄存器。要懂他的基本工作原理，他是如何级联的。
2、懂扫描，看清扫描方式。因扫描方式不同而导致的推送方式不同。
看左侧，col，这里说的是列，是控制列显示，看我给你摘下来的图片。他是控制一行中某列显示。
看右侧，row，这里说的是行，是控制行显示，看我给你摘下来的图片。他是控制一行显示。
综上，看我给你摘下来的图片。我截出的点阵，控制第一行，第三列。
在这个原理上，你想看一下他的具体流程，你这样弄
void display(unsigned char *p)
{
unsigned char i;
for(i=0;i<32;i++)
{
if(i<16)
{
send_data_row(0x0000);
send_data_col(sel);
send_data_row(*p);
p++;
delay(2);
}
else
{
send_data_row(0x0000);
send_data_col(sel[i-16]);
send_data_row((*p)<<8);
p++;
delay(2);
}
}
}
第一：屏蔽else里面的东西。看如何分屏显示。
第二：加大延时看分屏扫描方向。
结合原理和调试方法，你就能看出他的显示方法了。但个人感觉，这个程序做的一般，你想看看我的程
序吗，我有一份自己编写的，比这个好看，但是放哪了，我忘了，如果你想的话，说一声，我抽空帮你
写一个。
