Overview

This file contains a design example using the XDpTxSs driver in single stream (SST) transport or multi-stream transport (MST) mode.

Note
For this example to display output, the user need to implement initialization of the system (DpTxSs_PlatformInit) and after DisplayPort TX subsystem start (XDpTxSs_Start) is complete, implement configuration of the video stream source in order to provide the DisplayPort TX Subsystem HIP input. The functions DpTxSs_PlatformInit and DpTxSs_StreamSrc are declared and are left up to the user implement.
MODIFICATION HISTORY:
Ver  Who Date     Changes


1.00 sha 07/01/15 Initial release. 4.1 ms 01/23/17 Modified xil_printf statement in main function to ensure that "Successfully ran" and "Failed" strings are available in all examples. This is a fix for CR-965028.

Function Documentation

u32 DpTxSs_MstExample ( u16  DeviceId)

This function is the main entry point for the MST/SST example using the XDpTxSs driver.

Parameters
DeviceIdis the unique device ID of the DisplayPort TX Subsystem core.
Returns
  • XST_SUCCESS if DisplayPort TX Subsystem configured in SST/MST successfully.
  • XST_FAILURE, if DisplayPort TX Subsystem failed to configure in SST/MST.
Note
None.

u32 DpTxSs_PlatformInit ( void  )

This function initialize required platform-specifc peripherals.

Parameters
None.
Returns
  • XST_SUCCESS if required peripherals are initialized and configured successfully.
  • XST_FAILURE, otherwise.
Note
None.
u32 DpTxSs_StreamSrc ( u8  VerticalSplit)

This function setup stream source to input DisplayPort TX Subsystem.

Parameters
VerticalSplitspecifies whether to split video frame vertically into two different vertical halves.
  • 1 = Vertically split input frame
  • 0 = No vertically split input frame.
Returns
  • XST_SUCCESS if stream source is configured successfully.
  • XST_FAILURE, otherwise.
Note
None.
int main ( void  )

This is the main function for XDpTxSs SST/MST example.

Parameters
None.
Returns
  • XST_SUCCESS if the MST/SST example passed.
  • XST_FAILURE if the MST/SST example was unsuccessful.
Note
None.
