OLED显示_oled setcursor精确到y像素

OLED显示16*16汉字

16*16点阵

void Draw_16x16(unsigned char x,unsigned char y,unsigned char N)//显示16*16汉字
{
	
unsigned int Num =N*32;
	unsigned int i = 0;
	OLED_SetCursor(y,x);		
	for ( i = 0; i < 16; i++)
	{
		OLED_WriteData(Tab16_16[Num]);		
			Num+=1;
	}
	
	OLED_SetCursor(y+1,x);		
	for (i = 0; i < 16; i++)
	{
		OLED_WriteData(Tab16_16[Num]);		
			Num+=1;
	}
}

OLED由128*64个像素组成

有8行,18行8个像素

显示32*64灵感:

OLED_SetCursor(y,x);        
    for ( i = 0; i < 16; i++)
    {
        OLED_WriteData(Tab16_16[Num]);        
            Num+=1;
    }

32*64字模一行有32个像素,有8行

"好"

 编写程序

void Point_32x64(unsigned char x,unsigned char y,unsigned char N)//显示32*64汉字
{
	
	unsigned int Num =N*256;			//定义一个汉字256像素
	 int i = 0;
	OLED_SetCursor(y,x);				//显示第一行
	for ( i = 0; i < 32; i++)
	{
		OLED_WriteData(Tab_32x64[Num]);		
			Num+=1;
	}
	
}

烧录后显示:

汉字宽度32,高度64,程序只写了1行,符合预期,使用for循环编写完整程序

void Point_32x64(unsigned char x,unsigned char y,unsigned char N)//显示32*64汉字
{
	
	unsigned int Num =N*256;
	 int i ,j;
	
	for( j=0;j<8;j++)
	{
		OLED_SetCursor(y+j,x);	
		for (i = 0; i < 32; i++)
		{
		OLED_WriteData(Tab_32x64[Num]);		
		Num+=1;
		}
	}
}
