Other Parts Discussed in Thread: THS8200

Hi,

I am trying to display color bar test in DM648_DVSDK/pspdriver. I was successfully tested VGA_60Hz, but did not get anything with SVGA_60HZ and SXGA_60HZ.

Can anybody tried with these display resolution(SVGA_60HZ / SXGA_60HZ)?

Please help.

-Thanks,

Prashant Jagtap.

    Hi Prashant,

    I guess, you are using the PSP 1.10.00. Can you please try out the "psp_bios_vport_vesa_colorbar.c" sample application for the video mode "MODE_SVGA_60HZ".

    This sample application basically will configure the display as,

    /* Vport Display driver configuration */
    static VPORTDIS_Params vDisParamsChan = DIS_PARAMS_CHAN_SVGA_60HZ_DEFAULT;

    /* THS8200 EDC driver configuration */
    static THS8200_ConfParams vDisParamsEncoder   = DIS_PARAMS_THS8200_SVGA_60HZ_DEFAULT;

    And also, please refer the section "Hardware setup and demo procedure for DM648 VESA Color bar" of the document "\pspdrivers_1_10_00\packages\ti\sdo\pspdrivers\drivers\vport\docs\BIOS_VPORT_Driver_UserGuide.pdf" for more info.

    Regards,

    Hi Sandeep,

    Thank you very much for your reply.

    The VESA color bar test works properly with some PC monitors and not with all.(I have check that the PC monitors supports the resolution.). I have test with SXGA resolution.

    I am not able to display same resolution working for one PC on other.(Any reason for this?)

    I am now trying with UXGA resolution but don't know how should I set the video clock for this resolution. Is there any generic method to calculate the video clock for a given resolution?

    -Thanks,

    Prashant Jagtap.
