MIPI Bridge Initial Code

1. 向2828 写command/data

// SSD2828 Command Mode (LP) Initial 
void Initial_SSD2828_CMDMode(void)
{
	SPI_2828_WrCmd(0xb9);
	SPI_WriteData(0x00);//1=PLL disable
	SPI_WriteData(0x00);
	// Configure setting
	SPI_2828_WrCmd(0xb7);
	SPI_WriteData(0x00);	
	SPI_WriteData(0x00);   
	// VC setting
	SPI_2828_WrCmd(0xb8);	
	SPI_WriteData(0x00);	
	SPI_WriteData(0x00);   
	// PLL setting
	SPI_2828_WrCmd(0xBA);//PLL=(TX_CLK/MS)*NS 8228=480M 4428=240M  061E=120M 4214=240M 821E=360M 8219=300M
	SPI_WriteData(0x14);//D7-0=NS(0x01 : NS=1)
	SPI_WriteData(0x42);//D15-14=PLL范围 00=62.5-125 01=126-250 10=251-500 11=501-1000  DB12-8=MS(01:MS=1)
	// LP clk setting
	SPI_2828_WrCmd(0xBB);//LP Clock Divider LP clock = 400MHz / LPD / 8 = 240 / 8 / 4 = 7.5MHz
	SPI_WriteData(0x03);//D5-0=LPD=0x1 – Divide by 2
	SPI_WriteData(0x00);

	SPI_2828_WrCmd(0xb9);
	SPI_WriteData(0x01);//1=PLL enable
	SPI_WriteData(0x00);
	// Channel number setting
	SPI_2828_WrCmd(0xDE);//通道数
	SPI_WriteData(0x00);//11=4LANE 10=3LANE 01=2LANE 00=1LANE
	SPI_WriteData(0x00);

	TimerDelay(100);

}

 

 

2. 发送RGB信号前Initial (Video信号配置)

	SPI_2828_WrReg(0xB3, 0x080c  );  	//H V  //HFP/VFP 
	SPI_2828_WrReg(0xB4, 0x0438  );		 //1200	   	V  
	SPI_2828_WrReg(0xB5, 0x0780  ); 	 //1920		H

	SPI_2828_WrCmd(0xb9);
	SPI_WriteData(0x00);	//1=PLL disable

	SPI_WriteData(0x00);
	// Color order setting
	SPI_2828_WrCmd(0xD6);//  05=BGR  04=RGB
	SPI_WriteData(0x05);//D0=0=RGB 1:BGR D1=1=Most significant byte sent first
	SPI_WriteData(0x00);

	// Delay setting
