Part Number: DLP3010EVM-LC

Hello
Mayank,

We are still evaluating the DLP3010EVM-LC.

The question is about the maximum exposure time.
I set Exposure Time in Internal Pattern mode
I want to set and operate up to 2 seconds.

However, it did not project normally.
The settings are as follows.


What is the maximum exposure time?

Thanks and regards,

Tak

  • Hello Tak,

    I will try to reproduce the issue at my end and will get back to you with my findings soon.

    Thanks and regards,

    Hi Tak,

    I was able to reproduce the issue.

    The reason behind this is that the given exposure time exceed the maximum limit of the exposure time supported by the system.

    If you are interested to display internal patterns with exposure time in the order of seconds, then i would request you to use the Trigger In mode of internal pattern display instead of the free running mode.

    Hi Mayank,

    Thank you for your great idea!!
    I was able to confirm that you could expose for 2 seconds using your method.
    My system uses internal pattern trigger input mode.

    However, there is one concern.
    I was able to expose for 2 seconds using EVM, but the image was noisy.
    I think the reason is a rough connection method to Trigger In.

    Did the pattern display correctly when exposed for 2 seconds in the Mayank environment?
    I want an answer to solve my problem.

    We are waiting for the evaluation results.

    Thanks and regards,

    Tak,

    Are you checking the status of the pattern ready signal before sending the triggers via trigger in input? The controller will ignore all the triggers given via trigger_in if the status pattern ready signal is low (assuming you have configured pattern ready as active high signal)

    Thanks and regards,

    Mayank

    Hi Mayank,

    Where I have correctly controlled the trigger input and ready output
    I was able to work properly.

    I was able to solve it with your idea.

    Thank you very much.

    Tak
