8 x 64 LED Dot Matrix Sign board. Test 1.0


Finally I built little bigger Dot Matrixs sign board. But still there is lot to improve. At the moment im working on character spacing algorithm.

And also you can see the characters isn’t go with the display. Thats because my character gen is for 5X7 displays not for 8X8.

I hope to post here all of my improvements on this project.

After I learn about the client requirement I always give them the better understanding and clear picture about, how the end product will function in real world. In addition to the client requirement, I also offer lots of options, features and improvements. And I always very concern about the end product quality.

      Thanks.

      Yes I have shared it with many people here. Also I uploaded it to few hosts. But files are deleted coz some punks report the links.
      I’ll mail you the project files. But sorry I do not have any schematics for the projects. Because hardware part is pretty easy.
      you’ll understand the hardware part when you examine the code.

      Bye.

    Pasan

    Many thanks for you response.

    Actually I’m trying to make something for me, but I’m new in this area.
    Can you tell me one thing, which development tool and compiler you used for this code?

    If you give the permission then I’ll ask some tips later when I need.

    what are you using to driving coloum of dot matrixs sir? using shift register or another?

    Like

  18. titut says:

    are you using that shift register to sending the data or just using to scanning the matrix coloum?
    I ever made some running text and digiclock using led matrix with scanning coloum (4017 decade counter use to scanning coloum) and the data is sending via parallel from the port of microcontroler.
    and I also try the shift register to send the data coulom (scanning matrix’s row) , but I found some difficult to adjusting data when I make running text, but easily to make unrunning character, like digiclock. can you explain how to adjusting data easily to built running text with data is sending use shift register.?
    sorry for bad english sir….🙂

      Hi there,

      No, In here I use shift registers to select the columns. Data load by port pins.
      This project is my fist ever project. It is a milestone for me. Then develop it bit by bit.
      Took some time but worth.

      Using 4017 will be total mess friend.

      There are many effective ways to scan a display. But depend on your skills and all.
      When you getting to know it better. Sure you will understand what I’m talking about.

      What language you are using. assembly, basic, c, C++ ?

      First u better load your data to a BUFFER ARRAY. Then change the buffer ( Scroll or some effects )
      Then shift out the data to your SHIFT REGISTERS.
