DLPC3478: Inquiries on DLP3010 & DLPC3478

Part Number: DLPC3478

Hi team,

Customer has a issue

I only use Blue LED.

I researched the SDK interface for a day. And I want to re-describe my problem in a technical way.
In your official interface "DLPC-API-1.10/api/dlpc34xx.h", I only found two interfaces I care about most:
DLPC34XX_ReadPatternOrderTableEntry(uint8_t PatternOrderTableEntryIndex, DLPC34XX_PatternOrderTableEntry_s *PatternOrderTableEntry)
DLPC34XX_WritePatternOrderTableEntry(DLPC34XX_WriteControl_e WriteControl, DLPC34XX_PatternOrderTableEntry_s *PatternOrderTableEntry)
What I am curious about is why the OrderTableIndex can be specified when Read the OrderTable, but the Index cannot be specified when Write it.
In addition, the Write interface DLPC34XX_PatternOrderTableEntry_s data structure can only specify one Pattern Set, and the function I want is to specify a set of Pattern Sets.
So, can you help me contact the developer of this SDK?
My purpose is to dynamically combine several Pattern Sets.

Can you provide support? The customer needs detailed guidance step by step.




  • Hello Vivian,

    Welcome to the TI E2E forums.

    Do you know if the customer has a chance to use Write Pattern Order Table Entry and Read Pattern Order Table Entry vis GUI? I would recommend them to compare the flow with GUI and API. 

    For generating multiple pattern sets, are they using internal or external pattern streaming mode? The maximum number of patterns can be used in internal streaming mode and limited by the external flash memory. I would also recommend them to generate the pattern sets via GUI and compare it with the API.

    Please come back to this thread if the customer has question.



  • Hi Lori,

    Thanks for your quick reply.

    I got the solution from API document.
    Thanks for your help.
  • Hi Vivian,

    Great, thank you for letting us know! I hope the API document is helpful, then I'll close this thread.
