lkl motors

The bresenham algorithm used in computer graphics to draw a straight line was originally used to control two motors on the X axis and Y axis on a plotter. Recently, a very similar stepping motor control problem was encountered, the bresenham algorithm can be used to solve the problem. Problem description: There are two identical stepper motors, with 8051 Single Chip Microcomputer to control the L297 + L298

You can enjoy the service of General Motors OnStar in about 200 yuan.GM's OnStar is very good, but it will cost thousands of dollars a year. The main realization of positioning, power off the anti-theft functions such as oil.There are, of course, some personal secretaries, rarely used functions.For cost-effective, many people only need car anti-theft function, when someone smashed the car, collision, or smashed the glass, want to steal the car items,

characteristics of brushless motor 1, there is no carbon brush, theoretically the rotor does not need to have a conductor on the outside of the link. 2, in the process of operation, the speed of the brushless motor depends on the frequency of alternating current, so the higher the frequency of brushless motor can turn faster. 3, brushless motor speed is strictly set according to the KV value, 1000KV means that each Ford Motor speed 1000 rpm. So when the voltage is 5V, the 1000kv brushless motor

Java collection classes are mainly derived from two interfaces: collection and map, the two classes are the fundamental interface of the Java Collection Framework, the rest of the collection is the subclass of these two collections, this blog is mainly about the collection interface and its system contains set,list,queue and other collections. This is explained in turn.I. Collection1.Collection is the parent interface of the Set,list,queue interface, and the methods defined in collection are als

Thinking in Java --- correct termination of sub-threads During multi-threaded programming, we often start multiple sub-threads to complete a task, so how to exit these threads correctly when the task is completed or when the task is running to a certain extent. We will discuss this issue below. I. Termination of a non-blocking taskThe termination of a non-blocking task is the simplest case. In this case, we can easily terminate the task correctly by setting the condition for the while () loop en

Collection of java Collection Learning (3) This blog mainly introduces the List set and Queue set. 1. List SetThe List set is an ordered and repeatable set. Each element in the set corresponds to an index, we can access the data in the List set through the index (in fact, it can be seen as a variable-length array ).List, as a sub-interface of Collection, supports all Collection operations. However, because List is ordered, some new operations are added, mainly insert and delete indexes, method o

you start the motor but the torque is insufficient so that it stops rotating. This is the maximum current of the motor, and thus the maximum power. So you have designed all the circuits to handle such a stopped current. In addition, if you plan to run the motor for a long time, or when the voltage is higher than the rated voltage, it is best to add a heat sink to the motor to avoid coil melting. How high is the rated voltage added to the motor? Generally, all

This blog mainly introduces the list collection and the queue collectionA. List collectionThe list collection is an ordered, repeatable collection of each element in the collection that corresponds to an index, and we can access the data in the list collection by means of an index (which can actually be seen as a variable-length array).List as a sub-interface of collection, supports all operations of collection, but because the list is ordered, new additions are made to the method of inserting,

position of the current load, indicating that the first data location should not be read or written.Location indicates the index of the next buffer location that can be read or written.The main function of Buffer is to load data and then output data. Therefore, we need to know the specific process: first, the positiion of Buffer is 0, and limit is equal to capacity. The program can use put () the method puts some data into the Buffer (or extracts some data from the Channel). In this process, th

Spring boot embedded container tomcat configuration, springtomcat This article introduces tomcat configurations of embedded containers in spring boot practice. The details are as follows: Default container Spring boot uses the default web program to enable tomcat embedded container tomcat and listen to port 8080. The default value of servletPath is/. You need to modify the port and context path. The modification method is simple in spring boot; Configure in the resource file: server.port=9090 se

The final keyword can be used to modify basic variables, and references can also be used to modify methods and classes. There are different meanings when modifying different objects, so it is easy to confuse them and make a summary here. Understanding the initialization of variables and the loading mechanism of classes can also give us a global grasp of what happens when a program is run.One. Final keyword1.1 Final keyword modifier variableThe final keyword is similar to the const keyword in C +

forwarding table of the switch Si is a set of switches. Definition 4: If no MAC address of other switches is displayed in the lij of the Si port of a vswitch, The SIJ port is called a leaf port. Definition 5: the port SIJ is complete. It means that the data frame sent to any device d in the stator network can reach Si through the port SIJ, then the MAC address of D must appear in lij. Theorem 1: If lij ∪ lkl = U (U refers to the collection of all swi
