DLP3010EVM-LC: About the maximum time of Exposure Time

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,

Mayank

Mayank,

I believe in you.
We are waiting for good findings.

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
