I bought a product from the manufacturer in the early years. The core was AT89C2051. The programs I saved were all password protected. Many devices were broken and needed to be re-programmed.
I can't ...
DC signal sampling is relatively simple. If the signal voltage exceeds the AD sampling range, you can divide the voltage or use other methods to attenuate the signal for AD sampling, and read the resu...
KiCAD 6 is about to be unavailable
(No one knows how close it is... it will most likely be between the second and third quarters of this year)
Peter published a comparison of the two on his blog. Ther...
Why can I use CreateFile, WriteFile/ReadFile on a USB HID device in Windows XP/2k... but not on WinCE? 1. I found this HID device (Name:sz:HID1:) under HKLM\Drivers\Active\2x\ 2. I used CreateFile to ...
Trends in Electrical Injury in the U.S., 1992~2002 James C. Cawley, Senior Member, IEEE, and Gerald T. Homce I originally used it for my own translation, but later I didn't publish it. I'm sharing it ...
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]

As an emerging microfabrication technology, micro-electromechanical system (MEMS) technology has begun to be applied in various fields. It can integrate functions such as inform...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
5. Identifiers and keywords of C language
A complete PIC microcontroller C language program usually consists of six parts: include files (i.e. header files 1, variable definitions, variable de...[Details]
General LED lighting has a current limiting resistor in the driving circuit, and the power consumed by the resistor has nothing to do with the LED light emission. In order to improve efficiency, a...[Details]
Flooded Batteries
This battery developed in Germany can be used to power flashlights, strobe lights and toys as long as it is filled with water. This battery can be stored for 50 years and can...[Details]
1 Introduction
There have been many studies on the detection and protection of power grid short circuit and line fault. The short circuit, overload and overvoltage protectors on the market have ...[Details]
Introduction
Liquid crystal, as a display device, is widely used in low-power products such as instruments, meters, and electronic equipment with its unique advantages. In the past, the displ...[Details]
Single-chip microcomputers are widely used because of their small size, powerful functions and low price. This article introduces the method of designing a micro electronic piano using the AT89C51 sin...[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]
Abstract: In recent years, with the establishment and grid-connected power generation of a large number of solar photovoltaic power stations at home and abroad, photovoltaic grid-connected inverter...[Details]
