I made a LM3S9B96 board by myself. It is the third version now. The Ethernet of the second version works fine. When the third version was just soldered, the Ethernet could ping the board, but it stopp...
Embedded learning, getting more and more confused? I am a junior student. From the beginning of my contact with embedded systems to doing experiments, it has been half a year. At the beginning, I vowe...
When thyristors are used for three-phase controlled rectification, as the conduction angle decreases, the conduction time of the thyristors becomes shorter and shorter, and the rated output current of...
Signals not related to transactions The Avalon interface provides control signals with system-level functions, such as interrupt request and reset request signals. These signals are not directly relat...
When using a buck circuit to step down the voltage, add a load at the output end. Why does the output voltage change with the load resistance? How can I make the output voltage stable? I would like so...
The Portable Digital Data Acquisition System (PDDAS) uses LabVIEW Real-Time and PXI to control the wind tunnel test and record air pressure data from 128 different channels.
"The LabVIEW Real-...[Details]
My colleague and I spent the day chatting in the hotel bar. We had met with several customers. We were both wondering how come these engineers we were meeting knew almost nothing about analog techn...[Details]
1 Introduction
Intelligent control instruments are one of the most commonly used controllers in industrial control. They are mainly aimed at a specific parameter (such as pressure, tempera...[Details]
In the analysis of electronic circuits, static analysis (also known as DC analysis) is the basis of circuit analysis. However, it is well known that electronic components are nonlinear, so the anal...[Details]
RS-422 and RS-485 are both serial data interface standards, which were developed and published by the Electronic Industries Association (EIA). RS-422 defines a balanced communication interface with a ...[Details]
Describe how to meet the challenges of complexity with a modern wiring design toolset. Option codes and expressions can simulate the variables of an automotive project. A full-featured tool suite c...[Details]
With the widespread application of new services and technologies in the communications industry, the scale and capacity of operators' network construction are getting larger and larger, and the ris...[Details]
Since AC mains power may experience power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations during supply, these factors will affect the continuous ...[Details]
1. Tips for charging UPS for the first time
After purchasing a new UPS, plug the UPS into the 220V mains power grid and charge it for at least 12 hours to ensure that the battery is fully char...[Details]
There are many types and styles of digital voltmeters in design and development. Traditional digital voltmeters have their own characteristics. They are suitable for manual measurement on site. Tra...[Details]
This article introduces a high-reliability, high-power automatic water supply device made with 89C2051 single-chip microcomputer, which has phase loss detection, over-temperature detection, over-cu...[Details]
At present, more than 40 fieldbuses have been developed in the world, among which CAN bus is suitable for application in automobile inspection lines because of its unique features such as strong re...[Details]
A stepper motor is a motor that converts electrical pulse signals into linear or angular displacements. However, the control of stepper motors is usually developed in assembly language or C languag...[Details]
1 Introduction
The stepper motor is an actuator of an open-loop servo motion system, which is controlled in a pulse mode and outputs angular displacement. Compared with AC servo motors and DC servo ...[Details]
In some motion control systems with simple control or low cost requirements, stepper motors are often used as actuators. The biggest advantage of stepper motors in such applications is that they ca...[Details]
