点阵

原理图

分类: 电子科技

网上的资料很少出现完整配套的16×16点阵的原理图和程序,而且这是经过桥哥实践验证了的,因此在此含泪托出。。呵呵。

成品整体照

原理图(由于图太大缩小了看不清,因此分块来发)

下面是驱动模块电路图

1、三极管部分

2、74HC595部分

3、引出接到点阵的排针

嗯硬件电路就是这样了,下面是程序。

 }
}

下面是上面程序用到的74HC595的头文件

//SCK上升沿读取数据(由高位送数据),RCK上升沿输出锁存数据  。没有严格的时间要求
sbit SI=P2^4;//数据口
sbit SCK=P2^6;//数据输入时钟线
sbit RCK=P2^5;//数据输出时钟线
void  Input(unsigned char dat)
{
 char i;
 for(i=0;i<8;i++)
 {
  dat=dat<<1;
  SCK=0;
  SI=CY;//取出最高位
  SCK=1;//上升沿
 }
}
void Output()
{
 RCK=0;
 RCK=1;//上升沿输出锁存数据
}

至此,点阵的完整资料已经给出来了,有不足和还需改进的地方或者错误还希望看到这篇文章的达人指出。。
