Multiple power supplies are used in parallel, using 485 communication, divided into master and slave. In the past, the slave address was set by dial code, or when the power module had a display screen...
Are there any common PCB package specifications? For example, for non-chip resistors with different powers, what are the corresponding pad sizes and via sizes? 3296 adjustable resistors, etc., which a...
I always do summarization and review in order to see the path I have taken in the past and to look forward. In addition, it may be that although I am a "damn engineering guy", I have always been a per...
I modified the USART program of the ALIENTEK_MiniSTM32_REVB0 development board and organized many programs into the main file. There was basically no change, just a move. As a result, I can send data,...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
System design is a complex process. It is not enough to just use ICs. There are many details to consider. This article uses a high-fidelity music playback system as an example to introduce how to s...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
Continuity test
A variety of devices need to be checked for continuity, including cable assemblies, printed circuit boards, and connectors to ensure that these components have the expected contin...[Details]
With concerns about the growing energy crisis, motor efficiency has become an important and timely topic. This is because motors use 63% to 70% of the electricity produced in the United States and ...[Details]
The TPS92210 is a single-stage LED lighting pulse width modulation (PWM) controller. The TRIAC dimmable solution not only regulates the LED current, but also achieves a power factor close to 1. The...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
In the "digital pressure measurement" experimental device of applied physics, the subject technical knowledge of analog circuits, digital circuits, sensors and single-chip microcomputers is used. In o...[Details]
Car lights, whether headlights, fog lights or tail lights, play an important role in driving safety. However, the material of the car lights determines that the probability of damage in a collision...[Details]
People who often surf the Internet until late at night, their families always complain that turning on the big lights in the living room affects their rest, but some people don't have keyboard ligh...[Details]
The production process of lithium batteries does not mention the previous processes such as material preparation, winding, liquid injection, and packaging, but only talks about the final formation ...[Details]
The power supply is the core component of a computer. Although it is not of high value, all computer components rely on the switching power adapter to provide energy, so the stability of a power su...[Details]
Based on the actual situation, a remote intelligent anti-theft alarm device for home use, connected to the telephone line, simple to operate, and stable and reliable in operation is designed. When ...[Details]
1 Introduction
CAN (Controller Area Network) bus is a kind of field bus. It is used in many industrial sectors due to its outstanding advantages such as high performance, high reliability, high...[Details]
1. Brief Introduction
With the continuous development and improvement of single-chip microcomputer technology, single-chip microcomputers have been widely used in all walks of life, and ...[Details]
