DLPDLCR660TEVM: Binary Image or Video

Part Number: DLPDLCR660TEVM
Other Parts Discussed in Thread: DLPLCRDC4422EVM, DLPC4422, DLP660TE

Hi Team, we would like to confirm with you if it is possible to show binary image or video with DLPLCRDC4422EVM + DLPDLCR660TEVM. If not do we have another method? 

Thank you very much.

Regards,

Mark

  • Mark,

    Can you clarify what it is that you are looking for?  Are you looking to display an arbitrary test pattern from within the DLPC4422 EVM firmware, without using an external Vx1 input?  If so, that capability does not currently exist in the TI.com deliverables for these EVMs. 

    There are a few built-in test patterns and a "splash screen" (a DLP Logo) that can be displayed without an external input.

    The DLPLCRDC4422EVM + DLPLCR660TEVM can display video via the Vx1 input.  There are recommended and alternate timings supported by the Vx1 input listed in the  DLP660TE_Vx1_Input_Video_Timings.xls file.  This file is available in the DLP660TE-FW: DLPC4422 Controller support firmware for DLP660TE DMD, downloadable here:  https://www.ti.com/tool/DLP660TE-SW

    I hope that answers your question.

  • Hi Gary, Thank you for giving clarification. Do we have an ideal Vx1 for this application?

    Thanks,

  • Mark,

    V-By-One®HS is an internal interface standard used to get data from a video front end to a display technology within a product.  It was chosen because it has commercially available solutions that our customers and partners already use in other products. 

    Unfortunately, V-By-One is not very end-user friendly as it is an internal interface bus (i.e.board-to-board, within a product).  There are no consumer products on the market that we are aware of that have a V-By-One output. 

    Internally we do have a front-end test board that we use for internal demonstrations and validation testing.  It is based on a product that many of our customers use in end products.  Unfortunately, it is not available to consumers and we are under NDA with the manufacturer not to disclose ANY details (including the manufacturer); so we are not able to recommend or refer to this solution (or the manufacturer).

    To test various timings, we have used the Astro VG-876 Video Signal Generator w/ VM-1876-M2 (V-By-One®HS unit) in our testing.  There is a mention of this video signal generator in the xls file I referenced previously.  

    Please note that the the V-By-One input is 8 lanes with a 600MHz pixel clock.  It is important to take this into consideration when choosing a source.  Many of them do not specify the V-By-One pixel clock.
