OLED显示一张图片

1.思路:

        void Oled_Show_Image(unsigned char *image) //
{
   unsigned char i;    //-128 ~ 127位
   unsigned int j;    //j要重新定义，因为要到达图片的最后一位
                                       //行 i没有问题，j有问题 i为1时，j要从128开始这样子才会刷屏
   for(i=0;i<8;i++)
   {
       Oled_Write_Cmd(0xB0 + i);   //page0 -- page7

       //每个page从第0列开始
       Oled_Write_Cmd(0x00);
       Oled_Write_Cmd(0x10);

       //每个page从0列到127列，依次写入0，每写入数据，列地址自动偏移
       for(j = 128*i;j<(128*(i+1));j++) //列 i等于0的时候，j<128 //i到7的时候 i+1=8, 其实就是j<8（i+1）最后j要<128*8
       {
           Oled_Write_Data(image[j]);
       }
   }

}

bug:

code unsigned char bmpImager[]={}；数组后面要加分号

效果演示：

代码:

#include "reg52.h"
#include "intrins.h"

sbit scl = P0^1;
sbit sda = P0^3;

void IIC_Start()
{
	scl = 0; //防止雪花
	sda = 1;
	scl = 1;
	_nop_(); //耗时5个微妙
	sda = 0;
	_nop_();
}
 
void IIC_Stop()
{
	scl = 0; //防止雪花
	sda = 0;
	scl = 1;
	_nop_(); //耗时5个微妙
	sda = 1;
	_nop_();
}

char IIC_ACK()
{
	char flag;
	
	sda = 1;   //就在时钟脉冲9期间释放数据线
	_nop_();
	scl = 1;
	_nop_();
	flag = sda;
	_nop_();
	scl = 0;
	_nop_();
	
	return flag;

}

void IIC_Send_Byte(char dataSend) //发送一个字节
{
	int i;
	for(i = 0 ;i<8;i++)
	{
		scl = 0;//scl 拉低，让sda做好数据准备
		sda = dataSend & 0x80;       // 1000 0000 获得datasend的最高位
		
		_nop_(); //发送数据建立的时间
		scl = 1;//scl拉高开始发送
		_nop_(); //数据发送时间
		
		scl = 0; // 发送完毕拉低
		_nop_();//
		
		dataSend = dataSend <<1;
