将字模代码添加到工程中
user→gui.c→oledfont.h→cfont 16[]

代码实现
test.c→test.h声明一个新的函数void TEST_name(void)；

然后在test.c中实现

void TEST_name(void)
{ 	
	GUI_ShowString(0,16,"631807060512",16,1);
	GUI_ShowCHinese(0,32,16,"浮空花园",1);
}

main函数

int main(void)
{ 	
	delay_init();	    	       //延时函数初始化 
	NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);	 //设置NVIC中断分组2:2位抢占优先级，2位响应优先级 
	OLED_Init();			         //初始化OLED 
	OLED_Clear(0);             //清屏（全黑）
	while(1) 
	{ 	
		TEST_name();
		delay_ms(1500);		
	  delay_ms(1300);
	}
}

函数说明——
GUI_ShowString() 的参数

• 参数一：X 坐标
• 参数二：Y 坐标
• 参数三：字符串（ASCLL码中的）
• 参数四：bit（表示字符显示格式，这里我用的 16 ，和汉字一样高）
• 参数五：显示样式（1：白字黑底；0：黑字白底）

GUI_ShowChinese() 的参数

• 参数一：X 坐标
• 参数二：Y 坐标
• 参数三：汉字点阵大小（这里使用的是 16×16 的，参数应该是 16）
• 参数四：要显示的汉字
• 参数五：显示样式（1：白字黑底；0：黑字白底）

显示效果

二、左右滚动长字符

代码实现
main函数

int main(void)
{ 	
	delay_init();	    	       //延时函数初始化 
	NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);	 //设置NVIC中断分组2:2位抢占优先级，2位响应优先级 
	OLED_Init();			         //初始化OLED 
	OLED_Clear(0);             //清屏（全黑）
	while(1)
	{ 
		OLED_WR_Byte(0x2E,OLED_CMD);        //关闭滚动
		OLED_WR_Byte(0x27,OLED_CMD);        //水平向左或者右滚动 26/27
		OLED_WR_Byte(0x00,OLED_CMD);        //虚拟字节
		OLED_WR_Byte(0x00,OLED_CMD);        //起始页 0
		OLED_WR_Byte(0x07,OLED_CMD);        //滚动时间间隔
		OLED_WR_Byte(0x01,OLED_CMD);        //终止页 1
		OLED_WR_Byte(0x00,OLED_CMD);        //虚拟字节
		OLED_WR_Byte(0xFF,OLED_CMD);        //虚拟字节
		TEST_name();
		OLED_WR_Byte(0x2F,OLED_CMD);        //开启滚动
		delay_ms(1500);
		delay_ms(1350);
	}
}

TEST_name

void TEST_name(void)
{ 	
	GUI_ShowCHinese(0,0,16,"重庆交大",1);
	GUI_ShowString(0,16,"631807060512",16,1);
	GUI_ShowCHinese(0,32,16,"浮空花园",1);
}
