NI-FPGA 1473R and Hamamatsu Flash4.0 V2 data transfer problem

[Willy0120]

Hi, Sir:

I use NI FPGA 1473R-LX110 board to connect with Hamamatsu Flash 4.0 V2 camera.

The camera is 10 tap 8bit with two MDR cameralink interface.

But the return image is like attachment.

The image is not right.

Do you know where is the problem?

The example is from the NI FPGA example.

Your snapshot indicates that the example you are using is for one One-Tap 10-bits camera.

I suggest you to select a correspond example that fit for 10 tap 8bit camera.

Hi, Ting:

I tried to use this example.

But the image is still incorrect.

I also asked Hamamatsu engineer.

Below is their response.

Flash 4.0 has very specific data read out.
Top half of image, line data output order is from center to top, and bottom half of the image, line date order is center to bottom.

Do you have any ideal for this problem?

Do you have NI PCIe-1433 or PCIe-1435?

It would be much easier to use these ready-to-use CameraLink cards.

It seems there are some built-in cam files let you to config the camera.

If you can only use 1473R, and you don't have any other option, then you might have to modify the FPGA part by yourself.

It would be very difficult to do this. You camera FAE has to cowork with you to make this work.

Those Orca .icd files appear to be for a much older camera, and I'm pretty sure would not work for the Orca Flash 4.0 V2.  However if the issue is simply the line ordering, then I presume that you could acquire the out-of-order image, and then reorder the lines downstream.

However it does appear that any of these cards, or the 1483R FlexRIO, all support 10-tap 80-bit acquisition at 85MHz which appears to be enough to acquire at the full frame rate, though I have not seen any official confirmation that the Orca Flash 4.0 V2 is supported - can anyone confirm?  Our local Hamamatsu rep thought not, but he was not familiar with the NI products.
