Modular LED Matrix Display
This project presents us a modular matrix led display based on the ATmega48 micro-controller. The main feature of this modular matrix display is that you can reconfigure it to form an arbitrary lenght LED display. Due to the simplicity of the design, it is easy to extend the communications protocol to more than one display chain to increase the height of the display. In this project, both single and double row examples are shown.

wow, 10x14LED matrix, it is display various pattern, isn’t it?
hostin put 50x7LED matrix? hmm..my idea you can use IC shift register 8bit. but it’s crazy, cause need 7 iC x 7 rows = 49 pcs. data input can directly feed from microcon or parallelport PC.

the code and schematic for the above circuit is available for download. Look for the link at the end of the article. I’m afraid that is all I can provide.

The links for downloading are not working anymore.
Where can I find the documents?
