用汇编编写的密码锁，proteus仿真，程序，原理图全套，希望对需要的人有用-Compilation prepared by using locks, proteus simulation, procedures, a full set of schematic diagram, in the hope that those who need it useful

实现高级电子琴的程序，并实现若干扩展功能。 基本功能：用8257键盘输入对应的七个音阶，通过实验箱的喇叭发出声音，并通过七段数码管显示输入音阶； 扩展功能：1、录音：记录所弹奏曲目 2、放录音：任意时刻重放最新记录曲目 3、在程序中可预设一曲目，按一键实现播放该曲目。 4、在播放录制曲目或预设曲目时，按8279键盘上任意键可以暂停播放，再按一次从暂停处继续播放。 5、程序运行时有友好的用户介面 -Realize high-level organ of the process and realize a number of extensions. Basic functions: keyboard 8257 corresponds with the seven scale, through experimental sound speaker boxes, and through Seven-Segment LED display input scale the expansion of functions: one, sound recording: Record the playing pieces 2, released recordings: any time replay music 3-to-date records, in the proceedings may be the default one track, according to realize one key to play the tracks. 4, recording tracks in the player or the default program, press any key on the keyboard 8279 can pause playback, press once again to continue from the suspended players. 5, is running friendly user interface

一、 使用键盘显示接口芯片8279接收按键键值，并在七段数码管上显示出来，通过判断键值进入相应音乐播放处理程序。在音乐播放程序中，使用定时器/计数器8253的计数器2，使其工作在方式¬ ¬ 3―方波发生器，通过查表依次取出乐曲频率值送入计数器作为计数初值，经out2输出方波，驱动扬声器发出不同频率的声音，在每个音阶之间加入相应的延迟时间，即实现了音乐的播放。-First, the use of a keyboard display interface chip receive keys keys 8279, and Seven-Segment LED display, through to determine the corresponding music player keys to enter the treatment program. Procedures in the music player, use the timer/counter 2 counter 8253 to work in the way ? ? 3- square-wave generator, followed by out music through the look-up table values into the counter as a frequency count of the initial value, the output side out2 waves, driven loudspeakers of different frequency sound, in between each scale by adding the appropriate delay time, namely, the realization of the music player.
