Part Number: DLP4500

Tool/software: Linux

If there is another development board, and the picture is burned into this development board, the development board HDMI is connected to the DLP 4500 projector HDMI interface, can the development board trigger the projector projection? At present, I use the development board to trigger the projection for the projector pulse signal. The projection is not successful. I wonder what the problem is?Consult, thank!

    Hello Joyce,

    Could you please clarify what you mean by "development board"? Are you using a front end development board that you would like to use to trigger the Lightcrafter 4500? If so you will want to setup the Lightcrafter 4500 to use a pattern sequence with external video. You can find more info in our user's guide at www.ti.com/.../dlpu011f.pdf.

    Thanks,
    Kyle

    Hi Joyce,

    You want to stream the patterns from HDMI source coming from your development board, is that correct? When streaming patterns from external source, the patterns are triggered by VSYNC. If vsyncs are sent from your development board then you'll be able to get proper projection.

    Thanks & Regards,
    Hirak.
