Image Display: Need Help

I again tried to saveto LV 7, but the similar thing kept happening.

Anyway, basically my code is using "Draw Cartesian Axes.vi", "Draw Text at Point.vi", Draw Text at Point.vi etc.

Now, if you read the word document that I attached to my previous post, you would see that I want more grids. Usually the scales along X- and Y-axes are in micrometers and I would want grids each 250/500 micrometers on my display. Please let me know how to do it.

Thanks,
Dushyant

Hi,

Sorry, I could not save in LV 7.

However, Since I have made only some minor changes in the codes that was already in LV directory, I have pasted the block diagram of subvi in word doc.

Thanks,
Dushyant

Hello Justin D...  I have a problem displaying Image .. I am sorry dushyant to write directly in your thread

I have a spreadsheet data which has 286*516 Pixels data. Data is 16bit (from which only 12bit is usefull). Each data is a Level of a Pixel. I want to Display Grayscale Image.

I have used 3D Graph to display it and projection XY selected . I am getting My image as grayscale Image but somewhat slow display if I continously run it.

Second Method I tried is Directly "some 2D Graph" ( Sorry I forgot the Name.. I will get it next time) which directly display that 16 bit spreadsheet file. But it has only 255 levels so it didn't utilized my data and resolution is poor.

My doubts are..

1. Is 3D graph method I am using is Actually displaying my 16 bit image.
2. In 3D graph method : Because of that 12 bit format of my data and I had to convert it in 16 bit I am loosing any levels or       
    Resolution ?
3. Is there any way of increasing 255 level to 16bit level 2D Graph method.
4. Is there any method that can display my 16bit information as a image utilizing all my levels.

Please Do me a favor .. thank you

Hello Craig D
 
I am Rajesh G, we have tried AM modulation using only labview and we did it. But now we are working with 5640R board and its using LAbview and FPGA,
So we have gone through datasheets and some examples, but still we haven't understand how correctly to implement the HOST and FPGA target.
 
Please give us a clear idea so that we can understand " how to use HOST and FPGA target in a proper way"
 
One thing " we did AM using FPGA gates only and we compiled and downloaded it successfully, yet it all happend for upto 1MHz frequency.
 
Here we are working with 21.4 MHz of carrier frequency......
 
We are in urgent... becasuse our project os on HOLD due to this problem....
 
Waiting for ur reply
 
Rajesh G
