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
I used to manage the Java project with Maven and now I'm writing a Scala project.But the difference between compiling a Scala project in Scala-ide and SBT has never been clear.Subject to the article:http://my.oschina.net/yjwxh/blog/601566To find out the relevant information SBT official website is http://www.scala-sbt.org/ Span style= " font-family: ' microsoft yahei '; font-size:18px; "> The documents on
S7-300 PLC Siemens
This article is a small program of learning S7-300, used for the simple and intuitive understanding of PLC Development.
1. circuit diagram of three Asynchronous Motors
2. PLC control wiring diagram
We can see that the control button is connected to the i0.0 and i0.1 ports of the PLC signal module SM, and the output signal is output from q4.1.
3. plc sm module selection
1) Select sm321 di32 * 24 V for the input module
2) Select sm3

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

Scala eclipse sbt Application Development
Scala has a relatively complete Eclipse IDE (Scala IDE for Eclipse). for developers who do not want to migrate from eclipse to the Iea platform, it is particularly important to compile and package Scala applications in Eclipse to develop Scala applications conveniently, quickly, and effectively. Sbt is a building tool similar to Maven. We will use it to build the pu
SBT Introduction
SBT is a code compilation tool, is the Scala world mvn, can compile Scala,java, etc., need java1.6 above.
SBT Project Environment Establishment
SBT compilation requires a fixed directory format, and requires networking, SBT will download the dependent jar

ANT's need for us to define all of the target, the other builds have a basic enough task built into it, and they all employ the industry-accepted Maven directory layout. It's also the introduction of project dependency Management from Maven, so Maven is a milestone.
We often go into pages like this when we search for Java third party dependencies http://mvnrepository.com/artifact/com.google.guava/guava/19.0
I also found out from here that there are so many build tools to choose from, where
Because Scala has a more complete Eclipse IDE (Scala IDE for Eclipse), it's easy, fast, and convenient for Dev who doesn't want to migrate from Eclipse to the IEA platform. It is particularly important to compile and package the development of Scala applications under Eclipse. SBT is a build tool similar to MAVEN, which we will use to build the publishing program.This article describes the general steps for building an Eclipse development Scala applic

SBT is using Ivy to manage project dependencies, like the Maven project where you can use Dependency:tree to show the dependency tree, so how do you view project dependencies for a SBT project? This article mentions three ways to show project dependencies, which are Shell scripts, custom SBT tasks, and Sbt-dependency-p
