There are many places in PCB design that need to consider safety spacing. Here, they are temporarily classified into two categories: one is electrical related safety spacing, and the other is non-elec...
You can start when you want to press the switch, pause when you press it again, and continue when you press it again. Or you can have more switches....
There is no response when debugging the I2C program, but I wrote it strictly according to the timing, and checked the address, and there is no error. I would like to ask experienced I2C experts, what ...
Dear experts, has anyone used STM8S103K3 to make touch buttons? I have just come into contact with STM8 microcontrollers. I don't know much about it yet. Can any expert share a principle for reference...
My potentiometer, used as a bias voltage circuit, had the pins at both ends connected incorrectly when I was actually soldering it, but the middle pin was connected correctly, causing the experimental...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();

1 Introduction
Solar street lights are mainly composed of four parts: solar photovoltaic cell components, batteries, charge and discharge controllers, and lighting fixtures. The bo...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
Electronic systems are located at different points on the automotive power bus and therefore often need to operate under very stringent power requirements. These include load dump, cold crank, very lo...[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]
1. System Structure
This system is a simulation system of indoor air-conditioning temperature/humidity control system. The data acquisition and control center collects temperature/humidity...[Details]
1. Introduction
Testing the temperature of steel billets before rolling is an important measure to ensure the quality of steel. Traditional manual testing is difficult to ensure product qu...[Details]
Overview
In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[Details]
