秋大佬详细解释一下下面的代码，oled写数据

void OLED_WrDat(unsigned char IIC_Data)
{
IIC_Start();
Write_IIC_Byte(0x78);
Write_IIC_Byte(0x40); //write data
Write_IIC_Byte(IIC_Data);
IIC_Stop();
}
oled写命令
void OLED_WrCmd(unsigned char IIC_Command)
{
IIC_Start();
Write_IIC_Byte(0x78);
Write_IIC_Byte(0x00);
Write_IIC_Byte(IIC_Command);
IIC_Stop();
}
oled写坐标
void OLED_Set_Pos(unsigned char x, unsigned char y)
{
OLED_WrCmd(0xb0+y);
OLED_WrCmd(((x&0xf0)>>4)|0x10);
OLED_WrCmd((x&0x0f));
//OLED_WrCmd((x&0x0f)|0x01);
}
oled全屏
void OLED_Fill(unsigned char bmp_dat)
{
unsigned char y,x;
for(y=0;y<8;y++)
{
OLED_WrCmd(0xb0+y);
OLED_WrCmd(0x01);
OLED_WrCmd(0x10);
for(x=0;x<X_WIDTH;x++)
OLED_WrDat(bmp_dat);
}
