This the snake game... It s better to set the "step delay" to "0" before running, it requires fast processing. You can control the snake using arrow keys on your keyboard. All other keys will stop the snake. Press ESC to exit. -This is the snake game... It s better to set the "step delay" to "0" before running, it requires fast processing.

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.

此程为普通的I/O口驱动LCD,很有和用,希望对大家有帮助-This way for the ordinary I/O port driver LCD, useful and used, in the hope that everyone has to help

狼羊白菜问题农夫带着狼、羊、白菜从河的左岸到河的右岸，农夫每次只能带一样东西多河，而且，没有农夫看管，狼会吃羊，羊会吃白菜。 提示：利用图论解决问题。（用农夫、狼、羊、白菜及其在左岸还是右岸等表示图中的顶点）-sheep

基于Intel 8253定时器的两端Asm，包括配套电路，流程图  1。设计基于ISA总线的Intel 8253 的接口电路，用Intel 8253 的1个通道作定时器，演奏C调的各个音符，利用查表程序的方法依次演奏，每个音符演奏1s，停0.5s 演奏三遍后退出程序 2。利用Intel 8253的一个通道产生一个100Hz的方波，用示波器测试信号的正确性  以产生的方波作为另一个通道门控信号。利用此通道测量其高电平的宽度，在PC机显示屏上显示其数值并退出程序 -based on the Intel 8253 timer at both ends of programmers, including matching circuit, flowchart

用89C51，外接晶振，复位电路，二个数码管，二个按键，做一个电子秒表，具体要求为用按键起停电子表，可用按键设计倒计时时间(如10S，20S，60S),并启动倒计时功能,能用按键选择以上两功能之一-With 89C51, an external crystal oscillator, reset circuit, two digital tube, two buttons, making an electronic stopwatch, and specific requirements for the use button start-stop electronic watches, key design can be used countdown time (such as 10S, 20S, 60S), and start the countdown function, can be used for more than two buttons select one of the functions
