DLPC350 Pattern Trigger

Q1) When you apply the settings and play the sequence if you are noticing the Sequence Abort in the status flag; you can either increase the Pattern Period or just keep the Pattern Exposure = Pattern Period.

Q2) You can set Pattern exposure = Pattern Period = 232 then 'clear' the check box 'Clear DMD after exposure' this will yield the maximum speed.

Hi,

>Q1) When you apply the settings and play the sequence if you are noticing the Sequence Abort in the status flag; you can either increase the Pattern Period or just keep the Pattern Exposure = Pattern Period.

Pattern Exposure = 236uS (4225Hz ≒ 236uS)
Pattern Period =467uS

Do you this setting there is a problem?
There was no error in the entry of ”Sequnece Validation and Control”.


>Q2)You can set Pattern exposure = Pattern Period = 232 then 'clear' the check box 'Clear DMD after exposure' this will yield the maximum speed.

OK. Thank you.

Q1) Although GUI is not showing the error condition, if you see in the Status, if it is showing Sequence Error, you have to adjust the pattern exposure timings.

Hi, Sanjeev.

>Q1) Although GUI is not showing the error condition, if you see in the Status, if it is showing Sequence Error, you have to adjust the pattern exposure timings.

OK. Thank you.

Let me question additionally, please.

My customers are the following settings.

　・Pattern Exposure = 250uS

　・Pattern Period = 500uS

The waveform of the case will be below.

Q3)

I hope that the Pattern Period is 500uS.

However, it has become a Pattern Period = 540uS.

How will it be Pattern Period = 500uS?

Q3) Can you measure the TRIG_OUT_2 duration? It should show 500us. Now within the TRIG_OUT_2 there is TRIG_OUT_1 ON time that will map to the pattern exposure time - 250us.

Sanjeev

Hi, Sanjeev.

Thank you for reply.

>Q3) Can you measure the TRIG_OUT_2 duration? It should show 500us. Now within the TRIG_OUT_2 there is TRIG_OUT_1 ON time that will >map to the pattern exposure time - 250us.

TRIG_OUT_2 = 20uS

I want to set as follows.

Pattern Period = 500uS
Pattern Exposure = 250uS

How should a GUI be established?

Hi Hamada-san,

I think you are misunderstanding. 

I am asking TRIG_OUT_2 period i.e., Rising edge to the next rising edge that is the TRIG_OUT_2 period. I think you are measuring the just the pulse width.

Rising edge of TRIG_OUT_2 to next rising edge duration must be - 500us

The pattern exposure precisely maps on TRIG_OUT_1 signal.

SAnjeev

 

Hi, Sanjeev.

Thank you for reply.

Reply to this slower.

Rising edge to the next rising edge that is the TRIG_OUT_2 period

-> 540uS.

I want to Pattern Period = 500uS.

How should a GUI be established?

Check setting pattern period to 460us instead of 500us, do you get 500us period?
Regards,
Sanjeev

Hi, Sanjeev.

Thank you for reply.

It was set to Pattern Period = 460uS.

In that case, you get an error such as attachments.

Are there other ways to achieve it?

Is the specification of the current firmware?

Hi Hamada,
I am able to reproduce the issue you are posting in the beginning.
For 500us pattern period, please set Pattern Exposure = 231us and Pattern Period = 480 us.
We are seeing the pattern exposure is different from actual applied and we will let you know futher details on selecting different timing.

Sanjeev

Hi. Sanjeev.

Thank you for reply.

>For 500us pattern period, please set Pattern Exposure = 231us and Pattern Period = 480 us.

I checked the operation by the setting you showed.

　　Pattern Period = 500uS
　　Pattern Exposure = 231uS

My customers want to set Pattern Period = 500uS, Pattern Exposer = 250uS.


>We are seeing the pattern exposure is different from actual applied and we will let you know futher details on selecting different timing.


Do you have a plan of an update of firmware?

Hi Hamada-san,

Not immediately. It will take sometime before we update with the fix. Also currently we cannot give any time estimation.

Hi, Sanjeev.

For this matter,
Do you have any plans of a firmware update?

Best Regards,

Hi Hamada-san,
We have marked this particular issue for tracking; as of now we haven't started working on this. I cannot comment on rough availability date for the fix to be available in the firmware software.

Sanjeev

Hi, Sanjeev-san.

Thank you for reply.

I'm OK. Please tell me if there is an update.

Further, when the operation check under the following conditions,

Becoming LED Enable = H fixed.

●Condition

　- Pattern Sequence Mode

　- Video Port

　- Vsync

　- Pattern Exposer = Pattern Period

Because I think that it is an unintended behavior, thank you for confirmation.

Hi,

How about this case?
I'm waiting for a contact.
