Part Number: DLP6500FYE

hi,ykc

I am very confident that my connection is correct(DLPC900 to  DMD), but now there is no display.

Attachment is the drawing of my redesigned connection cable.  

Can switch DMD working mode through GUI   but there is no display.

I have sent the file to you by private message.

I am looking forward to your help.

Best regard,

Byron

    Thank you for your patience, we may need more digging.

    I think the probability of signal integrity is relatively small.

    Hi Byron,

    From last discussion, you are redesigning flex cable with 6 layers to resolve signal integrity.
    I am moving this thread to resolved till new cable comes up. You can reply to this thread once you have new cable. Thread will move to open state then.

    ok,The new cable is coming back soon ,I will update the status here.

    I have a new question, can I Invert the LED_EN?
  • In reply to Byron:

    Hi Byron,

    LED_EN can be inverted but it need a firmware change. It is not recommended as FW release on ti.com won't have it inverted.

    Hi ykc,

    Thank you for your reply,I will send you a private message.

    I just need to test it now, and It's not bad to think about it when you release new firmware.

    Yes. I have noted your request in future pipeline. I have sent you FW image in private.

    Ykc,

    The new FPC has come back,The test results are good.Thanks to your support before.

    The official FW can be used, but LED_EN still needs to be inverted.

    So still need to trouble you again. I have sent you a message in private.
