Lt7911d type-c/dp to Mipi scheme is mature and can provide technical support

 

One 、MIPI TX part

1、timing Partial reference Page2, Exactly the same .

2、Mipi video Mode selection and lane The configuration of numbers

// The following is MIPI Related configuration of , apply LT6911 and LT7911 series , about LVDS No configuration for output

MIPI g_MipiSetStr =

{ Port_4lane//Port_4lane & Port_3lane & Port_2lane & Port_1lane

, NonBurst_SyncPulse_Mode//Burst_Mode & NonBurst_SyncPulse_Mode & NonBurst_SyncEvent_Mode

, NonContinuousClock//ContinuousClock & NonContinuousClock

};

Lane Several parts must be connected with the back end MIPI Screen or SOC Corresponding ,Video The pattern combination is as follows , The specific choice depends on the back-end requirements ：

Burst_Mode+NonContinuousClock： Actually measured MIPI Clock It's discontinuous

NonBurst_SyncPulse_Mode+NonContinuousClock： Actually measured MIPI Clock Is a continuous

NonBurst_SyncEvent_Mode+NonContinuousClock： Actually measured MIPI Clock Is a continuous

3、mipi Format is set

void main(void)

{

g_GpioMode = GPIO_AS_OUTPUT;//GPIO_AS_INPUT & GPIO_AS_OUTPUT GPIO5 Output mode configuration ,DSI Used to reset the control panel

g_DisplayMode = VideoCopyMode ;//VideoCopyMode & SideBySideMode( double Port Screen use SideBysideMode Left and right pictures , single Port Screen output selection

VideoCopyMode)

g_OutputMode = RGB; //RGB & YUV422 & YUV444

g_MipiFormat = RGB888; //RGB888 & YUV422_8bit

g_MipiType = DSI;

//DSI & CSI

g_Pattern_TX_SEL = Pattern_MIPI_TX; //Pattern_LVDS_TX( apply 6211 and 7211 series ) & Pattern_MIPI_TX( apply 6911 and 6211 series )

g_ChipModel = LT7211D;//LT7211D & LT7211 about 6911 and 7911 Series does not need configuration ,LT7211D and 6211C Is choice

7211D,LT6211/6211B/7211/7211B Is choice 7211

if(g_Pattern_TX_SEL)

{

LVDS_Pattern_Setting(); //LVDS Output Pattern apply 6211 and 7211 series

}

else

{

MIPI_Pattern_Setting(); //MIPI Output Pattern apply 6911 and 7911 series

}

}

about DSI Dot screen application ：g_OutputMode = RGB;g_MipiFormat = RGB888;g_MipiType = DSI

about CSI Class applications are generally YUV422 Format ：g_OutputMode = YUV422 ;g_MipiFormat =YUV422_8bit;g_MipiType =CSI

VideoCopyMode Under each Port MIPI Output the same content ,SideBySideMode It's double MIPI Output left and right picture mode .
