单片机16x16点阵广告牌设计(含仿真+源码+论文+原理图) -

第一，如何取得代码。现在针对点阵的取字模软件很多，我们只需要打开软件，写入需要取字模的字，然后注意取字模的顺序，是横向还是纵向就行了。我们这里采用纵向取模，设置字模为C51格式。这样当写入的字确定后，我们就可以直接复制字模到程序中来实现相应功能。如“老”的字模就为：{0x02,0x10,0x22,0x10,0x22,0x20,0x22,0x20,0x22,0x40,0x22,0x7C,0xFE,0x92,0x23,0x12,0x23,0x22,0x22,0x22,0x26,0x42,0x2A,0x42,0x72,0x02,0x22,0x0E,0x02,0x00,0x00,0x00,/*"老",2*/}。
