About Binary Data Acquisition

[ikeda_kaoru]

I would like to add a program to the attached program to retrieve binary data.
The number of data being read from the FIFO is 198 x 256 x 256 = 12976128. I want to get this data as an array as binary data.
Thank you in advance for your help.

このデータを配列としてバイナリデータとして取得したいです。
よろしくお願いいたします。

I'm still very confused about what hardware you are using.  Do you really have an FPGA that can save all those images?  Why/how are you using the FPGA?

I'm assuming that you are saving the 3D data (the first dimension being X, the second Y, and the third Image # (or Z), with indexing on alternate X and Y possibly alternating (increasing/decreasing), the first thing to do is to transform the linear scan to a 3D (XY images x Image # = video) representation that you should be able to view in an IMAQdx Window display.  You'll read the data in 256 pixels-at-a-time, reversing every other scan (assuming you are using a "back-and-forth" scanning motion (and possibly also "flipping" every other 256 x 256 images, if you not only scanned left-rignt but also down-up Y scannng).  Juat read the image data 256 elements at a time and with the same logic that you used to run the scan, use it to reassemble the video images.

I computers, everything is "binary" one way or another, so you need to be much more specific.

Most of your code is highly disorganized and flawed. For example connecting a local variable to its own terminal is completely senseless. Then you have plenty of interactive greedy loops. Who wrote this? Does it work well?

This program was written by a senior who was in the lab four years ago. I have taken it over, but I do not understand it in some parts.
I will post a more specific explanation later.

Thank you in advance for your help.

I am using NI PXIe-8840 for FPGA processing.
I will explain the details of how I use FPGAs later.

Thank you in advance.

The PXIe-8840 is an older CPU/controller, no longer available from NI!

It has NOTHING to do with "FPGA processing" at all…

Hello. I have put together a pdf with specific things we would like to improve, and would appreciate it if you could check it.

Currently the program is working well and we would like to improve this program.

Please let me know if you have any additional questions.
Best regards.
