Example #2

File: oled.c Project: shenzihao6/myqudx

void OLED_WrCmd(unsigned char IIC_Command)
{
	IIC_Start();
	Write_IIC_Byte(0x78);            //Slave address,SA0=0
	Write_IIC_Byte(0x00);			//write command
	Write_IIC_Byte(IIC_Command);
	IIC_Stop();
}

Example #3

{
   IIC_Start();

Example #4

File: CN_SSD1306.cpp Project: AlcaldeWetPlate/Arduino-Dormitory-Assistant

//IIC写命令 -- 命令操作很少，对速度影响不大
void CN_SSD1306::Write_IIC_Command(unsigned char IIC_Command)

   Write_IIC_Byte(IIC_Command);
   IIC_Stop();
}

Example #5

File: CN_SSD1306.cpp Project: AlcaldeWetPlate/Arduino-Dormitory-Assistant

//设置起始点坐标

{

  Write_IIC_Byte(((x&0xf0)>>4)|0x10);//|0x10
  Write_IIC_Byte((x&0x0f)|0x01);//|0x01
  
  IIC_Stop();//SetPos函数经常被使用,所以采用了这种发送一组命令再关闭IIC总线的方式
}
