篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了十在屏幕上显示字符相关的知识，希望对你有一定的参考价值。
显示字符需要先实现绘点功能，然后用取模工具对需要显示的字符取模，我用的取模工具为PCtoLCD2002，设置如下图：
封装的函数最好比较容易使用，最好能选择字体，具体细节再此不详述，直接附上程序。

附上显示效果：
我在程序中实现了16,24,32,48,64这5种字体，支持的字符为“0123456789-: ”这13个字符，因为只要显示时间，所以就只实现了这13个字符，需要实现其他字符的话只需要修改对应的字体文件就可以了。需要支持其他字体也很方便，在draw.c第20行后面声明新字体的绘制函数，并在__g_draw_font_tab数组中将绘制字体的函数与相应字体大小关联起来。在draw.h第15行中的枚举类型中加入字体大小，需要注意的是字体大小一定要是偶数。
