硬件介绍

4针口的OLED

取模软件

下面这个.exe

打开后

显示效果

2.取模软件使用

设置

（1）字宽 20 ；字高 16；取消勾选"等比缩放"

（2）内部设置

点击这个齿轮

配置以下

生成字模

（1）在红色框中输入想要显示的中文，点击"生成字模"

（2）复制绿色框中显示对应中文的数组

具体为以下：

【这是多行多组的写法，此写法keil运行会乱码】

（3）易错：将刚刚复制多行多组的数组传给ai，帮我们转成单行连续

复制代码

3.代码

在 OLED.c 文件中添加显示中文函数 OLED_ShowCN

（注意：此时的字宽是20）

复制代码

//显示中文
void OLED_ShowCN(uint8_t Line, uint8_t Column, uint8_t Num)  
{      	
	uint8_t i;
	uint8_t wide=20;//字宽
	
	OLED_SetCursor((Line-1)*2, (Column-1)*wide);		//参数1:把光标设置在第几页. 参数2:把光标设置在第几列
	for (i = 0; i < wide; i++)
	{
		OLED_WriteData(OLED_F10x16[Num][i]);			//显示上半部分内容
	}
	
	OLED_SetCursor((Line-1)*2+1,(Column-1)*wide);		
	for (i = 0; i < wide; i++)
	{
		OLED_WriteData(OLED_F10x16[Num][i+wide]);		//显示下半部分内容
	}
 
}

在 OLED_Font.h 文件中添加显示对应中文的字模数组

注意 $40$

这里我的设置是字宽 20 ；字高 16，所以是40

若字宽 16 ；字高 16，应对应是32

复制代码

//对应中文的数组
const uint8_t OLED_F10x16[][40]=
{ 
    /* "董",0 */
    {0x00,0x40,0x44,0x44,0xC4,0xE4,0x64,0x5E,0x54,0xE4,0x54,0x54,0x5E,0x56,0xD4,0xC4,
     0x44,0x44,0x40,0x00,0x00,0x00,0x40,0x40,0x5F,0x5A,0x5B,0x5B,0x5B,0x7F,0x5B,0x5B,
     0x5B,0x5B,0x5A,0x5F,0x40,0x40,0x00,0x00},

    /* "哥",1 */
