"On the edge of life and death"! I have already made an interface with stm32, and also have a working mp3 project. Now I want to add this mp3 to this project. As long as it can play music, it will be ...
All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[Details]
In recent years, lighting has become an important area that countries around the world are targeting to promote energy conservation and environmental protection. According to statistics, about 20% ...[Details]
Battery life is critical for portable applications. For applications such as smoke detectors, security devices, and thermostats, factory-installed batteries need to last for more than 10 years. The...[Details]
The data collector of the automatic weather station is generally designed based on a single-chip microcomputer or a PC/104 bus controller. It has the characteristics of good compatibility with PC, low...[Details]
1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]
Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
Smart lighting control systems provide high controllability for various buildings and further enhance the level of green energy. They are the core products of energy conservation and digital techn...[Details]
With the continuous consumption of earth's energy and the scarcity of resources, the harm of greenhouse effect to human beings, and the serious pollution of the atmosphere to the earth, the intern...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
The traditional display screen using 51 single-chip microcomputer to control LED dot matrix has relatively simple functions. If it is to achieve diversified functions, it often takes a lot of time ...[Details]
FPGAs are used in 81% of electronic systems, including many commercial and defense products, and most FPGAs use BGA packaging. The BGA packaging is characterized by small solder balls and small sol...[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]
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]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
