When ISE calls Modelsim, there is no waveform output and the system freezes. After installation, various libraries were successfully compiled and their associations were realized. When I called MOdels...
I just bought a test board with two STC89C51RCs. I wrote several examples from the CD into it, and they all worked. But after I wrote one and burned it in, all the pins in the microcontroller changed ...
1. Is it necessary to use an external 32K crystal? 2. If a 16M crystal is used for frequency division, how should it be configured? The RTC I configured now takes more than 30 seconds to generate an i...

Floating-point digital signal processing has become a constant requirement for precision technology, often in applications requiring high accuracy in areas such as aviation, industrial machinery, a...[Details]
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]
introduction
For the voltage regulator modules (VRMs) that power the latest computer central processing units (CPUs), power supply designers have historically used multiphase interleaved b...[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]
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]
We know that the inverter consists of two parts: the main circuit and the control circuit. Due to the nonlinearity of the main circuit (switching action), the inverter itself is a source of harmoni...[Details]
In today's body control module (BCM) designs, savvy engineers are moving away from electromechanical relays whenever possible. Their next step is to eliminate fuses. But is eliminating fuses a nece...[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]
Today, with energy becoming increasingly scarce, the utilization of natural energy has become the focus of people's attention. Among various natural energies, the endless solar energy is highly fav...[Details]
This article will introduce a design method for a distributed control system used in a tracking car, which can perform distributed control of motor modules, sensor modules, and lighting control mod...[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]
