1. 使用PCtolLCD2003制作字库

注意,我们开始取模前一定要记得设置取模方式,这个取模方式和我们显示屏的显示方式要一致

1. 设置字体为宋体,字体大小为16*16(这里当然可以设为别的)

2. 输入想要显示的字

3. 点击生成字模

u8 shuai[] = {0x10,0x04,0x10,0x04,0x12,0x04,0x12,0x04,0x92,0x3F,0x92,0x24,0x92,0x24,0x92,0x24,
0x92,0x24,0x92,0x24,0x92,0x24,0x90,0x2C,0x88,0x14,0x08,0x04,0x04,0x04,0x02,0x04};

接下里我们来分析字模如何显示:

1. 字体大小为16*16,每一行用两个字节来表示,总共16行,也就时2*16 = 32个字节.

2. 第一个字节为0x10,二进制位0001 0000,我们想要显示出字体,只需要判断每一个bit对应的值是0还是1,当为0是显示背景色,为1时显示字体颜色,依次类推就可以显示出完整的一个字了

3. 由于我设置的时低位在前,因此第一个点是字节的最低位,如果选择高位在前,拿第一个点是字节的最高位.程序设计时要注意一下,否则显示的字会有乱码

2.显示16*16的字体

#define MID_FONT_H
#include "dev_lcd.h"/*****************************宏替换屏蔽硬件接口*************************/#define FONT_SET_WINDOWS(x, y, x1, y1)        LCD_SetWindows(x, y, x1, y1)

}
