Problem phenomenon: 1. When TLE7183F is powered on, there is no voltage difference between the output gate-source voltage, but the gate and source both have ground voltages, and the voltages are the s...
MicroPython was ported to an STM32F407 board. Due to hardware design reasons, only ordinary IO ports could be used to simulate SPI communication. Therefore, a MicroPython driver was written in C langu...
I have just started learning the uCOS system. Now I have a S3C44B0X board and want to port uCOS to it. So I found some uCOS source codes based on S3C44B0X on the Internet, but I don’t know how to use ...
Microcontrollers (MCUs), which are widely used in automotive electronics, are rapidly facing time and cost pressures. The main advantage of using MCUs has always been to create high-level system in...[Details]
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]

Since the No. 4 blast furnace of Handan Iron and Steel was put into operation in 1993, its external equipment has been seriously aged, and the original PLC control system TDC3000 of the hot blast furn...[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]
With the advocacy and implementation of the government's Safe City Plan, the security market has increasingly higher requirements for the clarity of surveillance images. Imagine that after a case o...[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]
LED technology has made rapid progress, and improvements in chip design and materials have promoted the development of brighter and more durable light sources, and the scope of light source applica...[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]
System Overview
The system consists of a signal preprocessing circuit, a single-chip computer AT89C2051, a systematic LED display module, a serial port data storage circuit and system software...[Details]
One in five car failures are caused by batteries, a problem that will become more serious in the coming years as electric-by-wire, start/stop engine management and hybrid (electric/gas) vehicles be...[Details]
DCDC means DC to DC (conversion of different DC power values). Anything that meets this definition can be called a DCDC converter. Specifically, it means converting the input DC into AC through a s...[Details]
The overall operating performance of an electric car depends first on its battery system and motor drive system. The drive system of an electric car is generally composed of three main parts: a con...[Details]
