基于51单片机的LED显示屏

湖北第二师范学院本科毕业论文Abstract:Due to the rapid development of technology,LED display screen hasbeen widely used in the streets.,and its application has been popularized in everyaspect of society.LED dot matrix has the characteristics of infinite cascade,with asmall display can piece together a large display,on many occasions can see the figureof it,is not only the application of it to make something appear more beautiful,moreimportant is that its application is convenient,cost is low,in addition to can give aperson visual impact,more can give a person a kind of beautiful enjoyment.LEDdisplays are arranged in a matrix by several light-emitting diodes,usually used todisplay advertising,graphics and other information.This design is based on the 16*16point array display of STC89C51 single chip.The LED display can display theChinese characters of 16*16 and display the image simply.The design includeshardware,software,debugging,etc.,which can realize the expansion of the displayscreen with simple cascade,but be careful not to exceed the load capacity.The designof this design is small,multi-function,convenient and practical,cost small,the circuithas the structure simple,the operation is convenient,the precision is high,theapplication is widely characteristic.Keywords:Lattice display Cascade 51 single chip microcomputer
