I implemented the matrix keyboard using the 4*4 query method provided by Zhao Youjian. My keyboard response always has problems. Sometimes it doesn't respond, and sometimes it responds several times. ...
Hardware designers have begun to adopt FPGA technology in high-performance DSP designs because it can provide 10-100 times faster computing than PC-based or microcontroller-based solutions. Previou...[Details]
This article discusses how to wake up a touch-sensitive device such as a tablet without touching the device, using basic gesture recognition and novel proximity sensors. The article discusses the p...[Details]
1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]

Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
Synchronous buck designs are becoming increasingly difficult, and the selection of suitable ICs is becoming quite narrow. This Design Idea combines a current-mode PWM IC used in a flyback regulator...[Details]
For a long time, my country has implemented "community-style collective heating" for hot water heating, and settled accounts based on the heating area, regardless of whether the user uses heat. Thi...[Details]
In the past 20 years, although the inverters that use power transistors (GTR) as inverter power devices, 8-bit microprocessors as control cores, and realize asynchronous motor speed regulation acco...[Details]
I. Introduction
The use of electronics in cars dates back to the early 20th century when electric starters replaced hand cranks. Automotive electronics became popular in the 1960s with the...[Details]
PID is proportional differential adjustment. You can refer to the detailed introduction in the automatic control course for details! The positive action and the negative action in temperature contr...[Details]
Many industrial fields such as industrial automation, logistics, and smart grids require that machinery and products be safe and have passed functional safety certification. When developing machine...[Details]
