Why does the inductance of common mode inductors change so much when tested at different frequencies? What is Rs? The higher the frequency, the smaller the inductance? Everything else remains basicall...
After downloading the RGB lighting program, I found that I could not download it via JTAG.
Since RGB's GPIO17 18 19 is reused with JTAG, after the RGB is turned on, the user code configures the pins a...
Temperature measurement circuit, waveform modulation circuit, peak detection circuit principleI don't understand the principles of these three circuits. Which one can you please tell me? Let's communi...
Preface
Turning on a light immediately after getting the development board is the minimum respect for the development board, so in this article we will talk about the onboard RGB light.

Power management solutions for today's portable application processors are becoming increasingly integrated. Total power consumption, standby and sleep current consumption affect battery size, bill...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[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]
The concept of state machine
State machine is an important concept in software programming. More important than this concept is its flexible application. In a clear and efficient program, ther...[Details]
Capacitors
are basic components in various electronic devices and are widely used for bypassing, coupling,

To understand how and why OLED power supply affects display image quality, you must first understand OLED display technology and power supply requirements. This article will explain the latest OLED...[Details]
introduction
Incandescent bulbs can emit a variety of light, but in specific applications, only green, red, and yellow light are usually needed - such as traffic lights. If an incand...[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]
1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[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]
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]
