我做过这样的毕业设计,16*64点阵显示屏,可以各种显示,时间,温度等功能。给你一个参考:可以去我的博客下载: 点阵汉字显示屏概 述这次比赛制作由于时间紧,同时为了降低制作难度, 仅作了四个字的轮流显示,实际使用时可根据这个原理自行扩充显示的字数。设计制作主要运用于学校的宣传栏,如:本科评估的各种信息,学校学院重要通知,天气预报等各种信息。系统设计一 硬件电路(1)系统组成:主要硬件电路:LED 点阵条屏是由 16 个 8*8 的 LED 点阵块组成,形成 16*64 矩形点阵,以AT89S51为控制核心。显示屏的其他主要硬件有:① 带锁存输出的 8位移位寄存器74HC595,作为LED的列线驱动输入;② 四六译码器 74LS154,作为 LED行线的译码选择(实际制作中考虑成本问题改为两个74HC138联合);③ 三极管 9012,连接四六译码器的十六个输出端,作为开关使用,驱动LED的行线。图二 AT89S51单片机最小系统AT89S51相关器件连接的接脚如下:PA0-PA3连接4-16译码器的输入口A,B,C,D;PB0-PB3连接74HC595的输入口 SI,SCK,RCK;PD6-PD7作串口通信使用连接RxD,TxD 两个三八译码器74LS138组成的16个输出端连接 16 个 9012的三极管的基极 B,发射极E 连接5V电源,集电极C连接到三个汉字点阵的16 个行线控制端。 点阵的 48 列数据线驱动由 6 片 74HC595 级联组成,前一片 74HC595 的 Q’H 引脚连接下一片的SI引脚,各片的SCK、RCK、SRCLR、G引脚分别并联。(2)LED点阵块图三 LED点阵块8*8的LED点阵为单色行共阴模块,单点的工作电压为正向(Vf)=1.8 v ,正向电流(IF)= 8-10 mA 。静态点亮器件时(64点全亮)总电流为 640mA,总电压为 1.8 v,总功率为 1.15 W。动态时取决于扫描频率(1/8或1/16秒),单点瞬间电流可达 80-160 mA。 16*16点阵静态时16*16*10mA,动态时单点电流80-160mA。实际测试:整机电流700 mA(2) 移位寄存器74HC595图四 74HC595内部逻辑图74HC595是带锁存输出的8位移位寄存器,其管脚见下图,其中SI是串行数据的输入端;VCC、GND分别为电源和地;RCK是存储寄存器的输入时钟,SCK是移位寄存器的输入时钟,SCLR是移位寄存器的输入清除,Q’H是串入数据的输出,G是对输入数据的输出使能控制,QA~QH串入数据的并行输出。从SI口输入的数据在移位寄存器的SCK脚上升沿的作用下输入到74HC595中,在RCK脚的上升沿作用下将输入的数据锁存在74HC595中,当G为低电平时时,数据并行输出。SCLR为移位寄存器的输入清除端。(3) 74HC138以及驱动电路图五 74HC138以及驱动电路实物图4-16线译码器(用两块74HC138组成),其管脚如图所示,A,B,C,D为译码的输入端,值的区间从0000到1111,Y1~Y15是对应A,B,C,D四个输入引脚的输出脚,其中选中的线用输出低电平,没有选中的输出高电平,G1、G2是使能端,只有输入相应D低电平才能使译码器正常工作。驱动三极管为16个9012,用万能板焊接。二 软件设计单片机方的程序设计 单片机在LED点阵汉字显示系统中主要负责数据的接收、存储和扫描显示 LED点阵屏三大主要功能。串行移动的子程序设计 这是一个通用子程序,在显示子程序中都要被调用,功能是移位寄存器 74HC595接收单片机发出的点阵行数据,逐位移动到对应位置后再进行锁存和输出工作,同时对四六译码器进行开关工作,控制屏幕的显示。部分程序:初始化程序:#include
