In addition to the microcontroller, microcontroller applications often include low-level sensor signals and appropriate power drive circuits, which require careful design of power and ground. This art...
I just browsed the 2009 readers' attention list selected by an online media. Can you guess what the most popular one is? Yes, it is "copycat"! Some people even call it "Chinese innovation". It is unde...
Chip giant Intel recently announced its entry into the SoC (system-on-chip) integrated circuit market. The SoC integrated circuit launched by Intel will be mainly based on the Atom processor and targe...
Some SD card commands are to transfer data, so when should DMA be performed? For example: Which of the following two sequences is better? Sequence 1. Send command first; then receive response; finally...
Today's computer peripherals are pursuing high speed and high versatility. In order to meet user needs, seven companies led by Intel launched the USB (Universal Serial Bus) bus protocol in 1994, wh...[Details]
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
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 public places such as schools, government agencies, factories and mines, as well as public corridors in residential areas, the phenomenon of long-burning lights is very common, which causes a h...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
The solidification and modularization of intelligent video analysis algorithms are the current trends in the application of intelligent video analysis technology. It perfectly combines intelligent ...[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]
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]
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]
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 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]
At very low temperatures, certain metals and alloys lose their resistance to electric
