TVOut for composite video on Omap L138

Other Parts Discussed in Thread: OMAPL138, TVP5147

Hello all,

Is it possible to output composite video from the Omap L138 (without other components)?
Here is how they do it with Arduino:

Has anyone tried to do it with Omap L1x processor?

Thanks,

  • Hi Yoel,

    We don't have examples for your requirement.

    We have composite video out on our LCDK boards in J9 connector connected through video decoder IC.

  • Hi Yoel,

    Thanks for your post.

    We do have VPIF_lcd_loopback example in OMAPL138 starterware package but the example application uses TVP5147 ADC to accept composite video or S-video input  and again, it uses ADV7343 DAC to output composite video/S-video. I mean, it accepts composite video input and composite video output only through ADC/DAC codec interface.

    According to meet your requirement with out using other board components, you need to implement the ADC/DAC software codec to be integrated along with your application to work for the DSP core stand alone.

    As Titus mentioned, there are no ready-made examples for OMAPL138 to output composite video with out using ADC/DAC codec components.

    Thanks & regards,
