读取DS1302的时间数据并用LED动态显示的51汇编（有注释）-Time to read the DS1302 data and dynamic display with LED compilation 51 (annotated)

本源程序是实现军用卷图机通过输入页码来是卷图机卷至指定得页码的功能，其中实现了卷动中相应页码输入，向前卷动，向后卷动，返回上次操作等操作，但由于时间原因在红外接口部分没有做好接口-the source is military aircraft through the volumes imported map pages is to map volumes to the designated machine rolls in the pages of the function, which achieved a scrolling pages corresponding input, scrolling forward and backward scrolling, the last operation to operation, But because of the time because in the infrared part of interface do not 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.

基于DS18B20温度传感器的设计程序 要求为：第一，由DS18B20获得外部温度信息然后通过数码管显示，显示值为三位，两位整数，一位小数。第二，判断温度是否大于 50℃，若温度在50℃以上，显示红色发光二极管发光；若温度在50℃以下，显示绿色发光二极管发光。-DS18B20 temperature sensor based on the design of procedural requirements: first, by DS18B20 access to external temperature information through a digital display, showing a value of 3, two integer, a decimal. Second, to determine whether the temperature is greater than 50 ℃, if the temperature at 50 ℃, which indicates that the red light-emitting light-emitting diodes if the temperature below 50 ℃, showing a green light-emitting diode LED.

在电子技术中，频率是最基本的参数之一，又与许多电参量的测量方案、测量结果都有十分密切的关系，因此频率的测量就显得更为重要。测量频率的方法有多种,其中电子计数器测量频率具有精度高、使用方便、测量迅速，以及便于实现测量过程自动化等优点，是频率测量的重要手段之一。在本次毕业设计中我们选择使用单片机来制作数字频率计，并在实际制作中采用了直接测频法。利用延时产生的时基门控信号来控制闸门，通过在单位时间内计数器记录下的脉冲个数计算出输入信号的频率，最终送入LCD中显示。这样制作出来的频率计不仅可以满足设计题目的参数要求，而且具有了单片机的稳定性和成熟性，且控制能力强，是一种低成本，高可靠的设计方案。-In electronic technology, the frequency is one of the most basic parameters, but also with a number of electrical parameters of the measurement program, the measurement results have a very close relationship between the frequency of measurement, therefore it is even more important. Measurement of the frequency of a number of means, electronic measurement of the frequency counter with high precision, easy to use, rapid measurement, and measurement is easy to realize the advantages of process automation is an important means of measuring the frequency of one. Graduates in this design we have chosen to make use of single-chip digital frequency meter, and used in the actual production of a direct
