Dear Carmen

OK, Thank you for information.

Dear Carmen

Thank you for your reply and support

1.

You may find details on CLHS trigger also in the official CLHS release 1v1 page 39 Table 3-3.

Excuse me, I did not find this document. Could you provide a link? thanks!

We have a problem with the image acquisition .

Image output format error (camera set test pattern to test)

https://www.dropbox.com/sh/05j…LovYNqZ5l41iKRenutSa?dl=0

Dropbox Link has error image raw data and GenIcam parameter 、problem VA file、 camera manual.

Could you help to check VA file. Thanks

Dear Sir

Because VA3.2.1 install direction not any mE5_marathon_VF2 VA example to refer.

Could you provide VA example of acquire image with external I/O (16K color Line Scan)

Like mE5_marathon_VCL ,We can send pulse to operator "CameraControl" CC1 .

Attachment is camera manual.

camera part name:ML-FC-16K04T-00-R (16K color line scan ,Two Camera Link HS LC fiber optic)

Thank you.

Dear Johannes

I will try the new JPEG operator of 3.2.0 version.

Thanks for your information and suggestion.

Oliver

Dear Sir.

Do you have C# example of JPEG_GRAY.

Now, we can work c++ example with LineScan and mE5marathonVCL.

If we want work on C# , do you have any suggestion.

(like:Use C++ to compiler DLL for C# to call in order to speed for "generate JPEG header store jpeg file on disc")

Thank you so much.

Dear Johannes

you want to output the pulse at the end of the frame correct? So if the blob ends at line 545 you still want the output at the end of the frame, correct?

YES

And now it's achieved when use "islastpixel"

thank you so much!

Oliver

Dear sir

I am try output one signal when image has any blobs (No matter how many blobs found only output one signal each image).

but i hope signal output timing same to image output timing when image has any blobs .

And I maybe found out why there is no synchronization (like below figure).

This is linescan case ,

Test line rate = 20K

do you have any suggestion?

Va file attached

thanks

Thank for your description.

Dear Carmen

Thanks for your solution

But, why it occur overflow when add Image Buffer.

BR
Oliver

Dear Carmen

We have a problem when i add sort feature . (if it is not add sort , acquire image&speed are normal)

we are use VCL board to run with 16K linescan.

ImageBuffer(module176) will be "FillLevel:75 Overflow:1"

microdisplay will stop acquiring after aquire 3 images (line period:24.5us)

microdisplay will stop acquiring after aquire 8 images (line period:100us)

I have add fifo & PARALLEup for image Buffer , but not effect.
Attachment is VA for you refernce

thank you.

Dear Carmen

Thank you very much.

1.

I have a question in below image , red box show bandwidth MAX only 125MByte/s.

And then , you only used two FrameBufferRandomRead operator on this design.

So , Max bandwidth will be limit to 250Mbyte?

Or ,here’s Bandwidth just show error value.

1.1.jpg

Because kernel columns is 32 on below image , can it add bandwidth?

1.2.jpg

This design is very helpful for ours.

Thank you very much!

Hi Johannes

thank your reply.

Do you want to reset ModuloCount to 0 using a sofware reset parameter? How can you guarantee that you do the reset exactly between two images?

Yes.We hope cycle number can be reset to 0 by software(when without stopping the acquisition)

this is customer's request , they can know when is end timing of scan a sample,

so, they have some time to do something before next sample start scan.

Or do you simply need a special sequence which you can define before starting the acquisition?

Are you mean like below figure? , i think this may solve the customer's problem. thanks!

pasted-from-clipboard.png

because a sample need scan 12 times , but original design maximum is 8 ffc data per cycle .

so , original sequence will like below

acquire:1 2 3 4 5 6 7 8 9 10 11 12

FFC data:1 2 3 4 5 6 7 8 1 2 3 4

so , next sample will from FFC data 5 to start.

for you reference.

BR

Oliver

Dear sir

We have case is need to do more FFC on a sample .

but some time will need special work.

normal work(FFC sequence): 0 1 2 3 4 5 6 7 1 2 3 . . .

special work(FFC sequence): 0 1 2 3 4 5 0 1 2 3 4 5 6 7 . . .

But we don't want frame grabber to stop acquisition .

pasted-from-clipboard.png

Now , We have not any idea for special work.

Do you have any good idea for special work.

Attachment is VA for you reference

thanks!
