From Baidu Duty Cycle The duty cycle (Duty Cycle) has the following meanings in the telecom field: In a string of ideal pulse sequences (such as square waves), the ratio of the duration of the Positive pulse to the total cycle of the pulse. For example, if the pulse width is 1 μs, the duty cycle of the pulse sequence

The school decided to break the original leadership of a person on duty, so that all teachers to participate in the work on duty, every day to arrange a shift leadership and a male teacher on the night shift, female teachers only value Saturday, Sundays and other statutory holidays daytime. Such a request, to the scheduling of the schedule brought trouble, both do not have to leave no one, do not miss every

I. the PWM output pin of stm32 is the reuse function of the I/O port. Ii. T2 ~ T5 these 4 Universal timers can output 4-way PWM--CH1 ~ . 3. We will use tim3's PWM output as an example to explain the text (other similar ), finally, we will provide the C code output by the two PWM methods of tim3 and CH2 (the test has been successful on stm32f103rbt6, so you can use it with confidence !). 4. The formula for calculating the PWM frequency and duty cycle i

Presumably we all remember a few years ago, to apply for the installation of telephone lines, for electricity charges toiled; today, the installation of telephone no longer need to wait, in front of the bank's operating counter can be long-distance phone calls and city charges together. These are just a few of the changes in the communications environment that we can feel firsthand, and these changes depend on the introduction of management techniques in the telephone switching network. In the

　　Single Responsibility principle (SRP): In the case of a class, there should be only one cause for it to change. 　　If a class takes on too much responsibility, it is tantamount to coupling these responsibilities, and a change in responsibility may be less likely to inhibit the ability of the class to perform other duties. This coupling is a fragile design, and when changed, the design can cause unexpected damage.　　Software design really has to do a lot of things, is to discover responsibilities

Problem:a class, only one causes it to change. There should be only one duty. Each responsibility is an axis of change, and if a class has more than one responsibility, these responsibilities are coupled together. This can lead to fragile designs. When a duty changes, other responsibilities may be affected. In addition, multiple responsibilities are coupled together, which can affect reusability . For exam

For help, how do I write the duty code on the website that is currently working on the organization? the foundation is very weak. many things are being read while Baidu is exploring. Recently, I want to display the employees on duty every day on the homepage, it is a four-day round. The code I wrote is as follows. Lt ;? Php $ zbb0 = array ( quot; Zhang San quot;, quot; Li Si quot;, quot; Wang Wu q hel

Last week on duty, encountering such a customer problem, the table structure is simplified as follows: CREATE table ' AA ' (' C1 ' int (ten) unsigned not NULL auto_increment,' C2 ' int (one) DEFAULT NULL,' C3 ' Int (one) DEFAULT ' 0 ',' C4 ' int (one) DEFAULT NULL,PRIMARY KEY (' C1 ')Engine=innodb DEFAULT Charset=utf8 When using the following syntax, how can I insert two records of C2 = 1007 and C3 = 1? Insert into a AA (C2,C4) Select 1007, 8 from dua

Separation of concerns (separation of CONCERNS,SOC) is the ability to identify, encapsulate, and manipulate concerns by "identifying, encapsulating, and manipulating" the software components associated with only "specific concepts, goals, and concerns". is a principle of dealing with complexity. Because the combination of concerns leads to a significant increase in complexity, it is possible to separate the different points of concern and deal with each other as a principle of dealing with compl

In the commonly used three-tier architecture, the data access layer is usually used to modify or query data, and general modifications and queries use the same entity. There may be no problems with some simple systems of business logic, but as the system logic becomes more complex and users increase, there are some performance problems with this design. Although some of the design of read-write separation can be done on db, there are still some problems in the business if they are mixed together

This is a good practice.After the release of Java 1.5, there are some problems caused by automatic boxing: Public classSetlist { Public Static voidMain (string[] args) {SetNewTreeset();

Idea: can be greedy, can also shortest way.Greedy writing: Because in the guarantee of legal premise, we choose the interval must be the right end point as far as possible, so we choose a legitimate and right end of the next interval is good (if there is no legitimate output-1 can). Time complexity O (NLOGN) (sort is nlogn, greed is O (n)).#include The shortest way to do this: interval [l,r] means you can go from l-1 to R, then we will l-1 a weight of 1 to the edge to r, and then because the in
