了解MCU代码中使用的字体头文件-解网

问：

MCU代码中有字体文件，用于在LED martrix显示屏上显示文本。

我想了解以下代码的包含字符宽度、字体数据、第一个字符、字符计数等。代码如何使用这些？我的最终目标是显示英语以外的语言。

让我们看一下 50 的条目，它适用于 ASCII 的。将 50 的线分成两行：'2'

0x18, 0x1C, 0x1E, 0x06, 0x86, 0xFE, 0xFC, 0x78,
0x18, 0x1C, 0x1E, 0x1F, 0x1B, 0x19, 0x18, 0x18, // 50 = '2'

从左到右，上行编码字形的上 8 行，下行编码字形的下 8 行，方式如下：

将每列的两个字节组合成一个 16 位的字节值，然后位 0 编码第一行，位 1 编码下一行，依此类推。

使用位 0 绘制字形，并使用位 1 的半字节值绘制字形，将出现字母的图片：.2
