4、SPI接口按键烧录

在正常点亮的函数后增加：

Get_BurnKey();

if(memcmp("0x01"))

{

Set_SPI(8,8);

//****OTP////////////////

Set_RESET(0,1);

Write_LCD_REG(0x0000,0x00F1);

Write_LCD_REG(0x0000,0x004c);

Write_LCD_REG(0x0000,0x0001);

Write_LCD_REG(0x0000,0x0028);

Write_LCD_REG(0x0000,0x0000);

Set_RESET(1,1);

Delay(2);

。。。。。。。。 OTP 代码。。。。。。。。

Delay(150);

Set_GPIO2(0); // GPIO2 SET STBYB low

Delay(150);

Set_POWER(1,1,0,1);//1.8V ON, 2.8V ON, 5V OFF, BL ON

Delay(150);

Set_POWER(1,0,0,1);//1.8V ON, 2.8V OFF, 5V OFF, BL ON

Delay(150);

Set_POWER(0,0,0,0);//1.8V OFF, 2.8V OFF, 5V OFF, BL OFF

Set_RESET(1,0);//MIPI RESET 1, LCD RESET 0

Delay(50);

Set_RESET(0,0);//MIPI RESET 0, LCD RESET 0

Delay(50);

Set_GPIO2(0); // GPIO2 SET STBYB low

Delay(50);

Set_POWER(1,0,0,0);//1.8V ON, 2.8V OFF, 5V OFF, BL OFF

Delay(50);

Set_POWER(1,1,0,0);//1.8V ON, 2.8V ON, 5V ON, BL OFF

Delay(50);

Set_RESET(1,1);//MIPI RESET 1, LCD RESET 1

Delay(50);

Set_RESET(1,0);//MIPI RESET 0, LCD RESET 0

Delay(50);

Set_RESET(1,1);//MIPI RESET 1, LCD RESET 1

Delay(50);

Set_GPIO2(1); // GPIO2 SET STBYB H

Delay(200);

}

5、I2C接口

（1）连接方式

（2）I2C书写格式

（3）I2C读的格式

读page7的00，设置值0X00=3C, 返回值也为3C。
