以ATmega16为核心设计的led点阵显示电路，两片4514作为编译码芯片，led作为显示器，可以显示字母、数字、汉字及符号，电路设计为8片8*8led串联显示，并可进行扩展以一次性显示更多内容，软件设计中程序中有的字模都可以通过led显示，字模取模是通过专用软件得到的。-To ATmega16 as the core design led dot matrix display circuit, two 4514 as the encoding and decoding chips, led as a display, can display letters, numbers, characters and symbols, circuit design for the 8 8* 8led series shows, and can be extended to a one-off show more content, software design programs are available through some matrix led display, matrix modulus is through special software to get.
