本设计中，通过51单片机作为控制器，74HC595作为LED点阵模块的驱动器，同时兼顾行驱动和列驱动，通过3根引脚跟单片机相连即可完成整个驱动显示，大大的节约了单片机的IO口资源，取代了传统的用专门的行驱动器，本设计中含有1块51单片机，16块74HC595传入并出驱动器，4块16*16LED点阵模块，通过Proteus仿真，有KEIL源程序，只要更改字库，即可完成想要显示的内容，是学习单片机点阵的好资料-This design in the, through 51 single tablets machine as controller, 74HC595 as LED lattice module of drive, while both line drive and column drive, through 3 root introduction heel single tablets machine connected can completed whole drive displayed, greatly of save has single tablets machine of IO mouth resources, replaced has traditional of with specifically of line drive, this design in the contains 1 block 51 single tablets machine, 16 block 74HC595 incoming and out drive, 4 block 16*16LED lattice module, through Proteus simulation, KEIL source, just change the font, you can complete the content you want to displayaremonolithic lattice of good information
