这是点阵程序
个人认为先学点阵再学lcd比较好
p0 p2分别接16*16点阵的高八位和低八位(纵向取模)
p3口低四位接4-16线译码器(74ls154)译码器低电平为列选
消除鬼影的方法:-This is the program individual lattice lattice before you think lcd is better to learn p0 p2, respectively, then 16* 16 lattice of high and low 8 8 (vertical modulus) p3 I received a low four 4-16 Line Decoder browser (74ls154) low-level decoder for the elimination of ghosting out the election approaches:

六位电子密码锁
采用89s52(51,52都可),4*4键盘,六个数码管,74ls04(位选),573(8D锁存器)。
说明:P2---数据(接573)―――(接数码管)
P1---位选 ---(按74ls04)
P0--4*4键盘
密码一次性设置(编程时写入的)
电路简单,此源程序仅供初学者学习,可自行扩展密码模块(加24C02)。
编绎软件为wave
