I want to separate the data for the return and destination of the scan and draw images in real time for each.

[ikeda_kaoru]

A 256 x 256 pixel image is drawn in real time.

From the point (0,0), it moves 255pixel in the x-axis direction, one round trip, +1 pixel in the y-axis direction, another round trip in the x-axis direction, +1 pixel in the y-axis direction, and so on, acquiring data Z at each pixel.

The acquired X,Y,Z data is read from the FIFO, and the image is created by replacing the XY index position data with the Z value. (The following image is the relevant part)

How can I separate the data in the x-axis direction for the trip and the return, and draw a 256x256 pixel image in real time for each? (Currently, only the return data is used for real-time image rendering.)

I am attaching the program and would appreciate your advice.

Initialize a 2D array of the correct datatype and place it in a shift register, then replace array elements with real data as a function of the two loop indices. The display needs to be inside the inner loop, of course

[altenbach]

Here's a very quick simulation...

Thanks for your reply.

I have checked the attached program.
With this program, it starts at (x,y)=(0,0), reaches (255,0), then scans to (255,1) and back to (0,1).

In my program, it starts at (x,y)=(0,0), reaches (255,0), then scans back to (0,0) without +1 on the y-axis. after one round trip back to (0,0), it scans again in the x-axis direction from (0,1) with +1 on the y-axis.

I am trying to separate the going only and returning only data on each of these lines and display two images in real time.

I would be happy to improve my attached program.

That should only require very minor tweaks to my code.

I will try to improve the program with the help of the program you gave me.
