Here is my schematic:
I want to scroll a vertical line on the matrix. How to do it using assembly language?
I have also started a thread under the topic GenerÃ¥te 2 wÃ¥ves of dÃfferent duty cycles on 2 dÃfferent port pÃns by usÃng both tÃmers in 8051
I want to implement the discussion of that topic in this schematic so that I could be able to get the vertical or horizontal scrolling line on the matrix display.
ajay_bhargav, has done this project already. I want help from you sir.
Thank you very much.

We already have tutorial for led matrix display in detail using assembly I think. Did you check it?

Yes, I had check already. But problem is that we have just few months that we started our this course i.e. 8051 and its interfacing. And your all tutorials have used very high language. I am beginner in this subject. But I know how to do things. So your schematics are helping me a lot but programming is just for high level students or you can say for an electronics engineers like you. So I want you to help me on this topic sir.
Thank you very much.
Thank you very much.

Thanks Shayaan for providing a feedback on tutorials. I always try to keep things as simple as possible but sometimes if peripheral is complex then programming will be complex too. Do let me know if you want to simplify a tutorial. I will try my best to keep it simple.
Regarding matrix display try to download the tutorial first and start reading it chapter by chapter. Tutorial is from majoka. Let me know if you couldn't find it.

Hello sir, I tried but I could not find it. Please let me through that tutorial.
By the way here is my project image and I tried my own program in the thread GenerÃ¥te 2 wÃ¥ves of dÃfferent duty cycles on 2 dÃfferent port pÃns by usÃng both tÃmers in 8051 and here is the image of that project in the proteus.
And I am also attaching the simulation of logic analyzer in the keil. You can see sir, I am getting my desired result in the simulations but still I am having a problem.
As you can see, in the Proteus, the dot matrix should display a line scrolling from downward to upward. Means at a time not all Lines should glow but only those which have grounded and the one which have high should be on the shift register side should not glow.
I hope you are getting my point.
Thank you very much.

Can you post your Proteus DSN file and your code.
