Answer 1

void rwe ()
{
temp = num[z][i*2];
io_595();
temp = num[z][i*2+1];
io_595();
i = i%16;
}
在这里，temp是16位的，num虽然定义是16位的，但实际有效数据是8位的，
改成一下试试：
void rwe ()
{
temp = num[z][i*2];
temp<<=8;
temp += num[z][i*2+1];
io_595();
i = i%16;
}

首先，先谢谢你的建议。
但可能还有错误哦
我把它写成这样
void rwe()
{
te = num[z][i*2];
te = te << 8;
mp = num[z][i*2+1];
temp = te | mp;
io_595();
i = i%16;
}
效果跟你的建议一样

追答

现在是什么样的，能上图片不？

追问

好吧，是我取模那弄错了，程序现在是木有问题的。谢谢你哈

追答

从图片看，16*16的LED已经全部可以点亮了，会不会是你的字模和你的程序不配套啊。

根据字模我画了好几个图，终于有一个像个字的：

所以，你的程序按以下试试：

void rwe ()

{

temp = num[z][i];

temp<<=8;

temp += num[z][16+i];

io_595();

i = i%16;

}

 

刚才在画图，没注意，你已经搞定了啊

追问

void rwe()
{
te = num[z][i*2];
te = te << 8;
mp = num[z][i*2+1];
temp = te | mp;
io_595();
i = i%16;
}
觉得这个比较好理解

追答

你是说“或”和“+”的问题，字模的问题？
或和加对于操作数0x00来讲是一样的，但是对于非0的来讲是有区别的。
至于字模，只要程序配合就行了。恭喜试验成功啊
