ni 1483 cam link 4 tap 16 bit with c-red2 from first light

[LUDO_27]

Hi I am new in camera link. I try to communicate via camera link under labview FPGA with module NI 1483. I can't find example with 4 tap 16 bits. On my test I always have 160*512 pixels. Does someone can help me with example ?

Hello,
I am also struggling with a similar problem. Do you have a solution?

What version of Labview are you using? 

I am using NI 1477 in camera link full in 8xU8 configuration.

What acquisition example are you trying to use? 

[Costa_V]

I am using LABview 2019 with a PXI and a flexRIO FPGA+NI1483 as frame grabber. The camera I am using is from the same manufacturer as LUDO.
The acquisition example I am using as base is Hardware Input and Output > FlexRIO > IO MOdules > NI 1483 > 1 Tap 10-Bit Camera with Frame Trigger and Threshold.
I got some success an adapting a 4Tap8Bit code and the further concatenating the bytes into a a word. My pixel intensities are off though.

Hi, this is what I do for return data from FPGA

Then for read

Hi Ludo,

The 1483 and the 1477 should be very similar.

You should be using the acquisition VI from NI to my opinion. 

Camera link acquisition VIs are in path: 

"C:\Program Files (x86)\National Instruments\LabVIEW 2018\vi.lib\visionFPGA\Basics\Camera Link Acquisition\CL Acquisition"

The VI that you could use is "IMAQ FPGA Camera Link 1 Tap 16-Bit"

Can you setup your camera to 1 Tap acquisition? NI processing VIs can process only single Tap for 16Bit.

I am still facing this problem, even if I am using an IMAQ based code. My architecture is simple a FlexRIO reads the cmera link and sends the data to my LabVIEW-RT. My current problem is, I am reading the pixels with the wrong intensity if compared with the measures done by the standard camera system. I am sending also screenshots of my code, the first image refers to the FPGA code and the second one to the LabVIEW-RT.Reading the Camera Link in the FPGA and sending the read data through DMA.Reading the DMA and assembling the frame.

Ludo,

Is this code working? Due to iamge size, I can't see the snapshot from your code well.

[LUDO_27]

Hi, yes the code is working. Change your web browser for see jpeg

Hi LUDO,

If your code is working. THen maybe it is only issue of bit shift to get the intensity correct.

Is your camera output is 16bit or less.
