[font=楷体_GB2312][size=3]Precise signal conditioning and high-resolution measurements are no longer limited to industrial or instrumentation applications. Designers of portable consumer electronic devi...
I just finished the course design, and I'd like to share a stopwatch program. The experimental version is Altera's EP2C5Q208C8, with a 50MHz crystal. The functions are reset, start and stop, and the d...
I am making a program to generate sine waves using the CORDIC algorithm. It is written in Q2, but modelsim can simulate the sine wave waveform, but the waveform captured by signaltap is reversed. I ca...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[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]
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]
As a simple and practical input device, buttons have been used in various microcontroller application systems and are ubiquitous. However, the buttons used in different practical occasions are also...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[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]
LED guardrail lights use fluorescent tubes or LEDs as light sources and continuous guardrails as carriers to form an approximately linear guardrail light strip. This article mainly introduces...[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]
Introduction
As the country increases its efforts to control the atmospheric environment, motorcycle emission regulations will become stricter year by year, and motorcycles that do not meet the...[Details]
