怎样将四块8x8的点阵变成16x16的点阵，以及怎样连接电路，还有给一个c语言程序吧！

这个就看你怎么应用了。假设你想用它来显示一个汉字。你想一下，88的点阵只可以显示简单的汉字，复杂的汉字就只能用更大的点阵了。更大的点阵表现力就更加丰富了。功能不多加叙述。
至于程序，其实还要结合电路。即点阵中有许多发光二极管，行列谁对应高，低电平，要清楚。单片机肯定带不动这个电路，故还有驱动电路。结合以上信息才能定义管脚。

横着看，有点的就相当于二进制1没有的就是0，比如第一行是00000010 00000000 转换成16进制就是02 00。

1616点阵汉字字模需要用32个字节数据表示。

16×16汉字点阵有16×16=256位二进制位来表示一个汉字的字形码。在计算机中，一个字节由8位二进制位组成。所以一个汉字是16 16个比特。一个字节是8比特。16 x16 ÷8 = 32个字节。故一个16×16点阵的汉字字模需以32字节的存储空间存储。

扩展资料：

点阵中的平行六面体称为阵胞。实际上，有许多种方式取平行六面体作为阵胞。描述阵胞的形状和大小采用3个矢量，即若以阵胞某角点为原点，沿3个棱边作3个矢量；通常面对我们的为a，向右为b，向上为c。它们之间的夹角分别为α，β和γ，称a、b、c和α，β和γ为阵胞的点阵参数。阵胞是点阵的基本单元，借阵胞的无限平移可以得到整个点阵。
