依照个人成绩进行考核,这是程序的主界面，主要包含其他模块的调用等-that is a programe for education

这是一个数字显示的源程序，希望大家借鉴使用-This is a digital display of the source, I hope everyone from the use of

ST套件产生汽车防盗器报警声,本实例的目的是让大家学会用单片机产生声音的方法，学会计算程序所用时间 本实例的功能是能用16F84产生汽车防盗器的报警声，频率分两个0.1s第一个 0.1S频率从1.8K-3.5K匀速增加第二个0.1S频率从3.5K-1.8K匀速减少, 程序复位后,按S2喇叭叫两声,按S3喇叭叫15秒,中途可按S5停止. PIC单片机 烧写时应注意：配置位已经在程序中写明，加载HEX文件时会自动加载，烧写时不用再手动设置配置位。 实验时请注意套件跳线选择；-pic

关于打印机的一个汇编语言程序，能用，但是希望有高手能够翻译成c语言的供大家分享-On a printer assembly language procedure, can be used, but would like to have a master can be translated into the language of c for everyone to share

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.
