I use Silicon Lab...IDE to debug C8051F320 USB communication program USBXPress and install it to Silabs\MCU. C8051f320.h, USB_API.h cannot be opened. How to solve it?...
I have two AT89C2051 microcontrollers (with LED electronic clock programs written in them). I want to reprogram them with other programs, add a 1602 screen, and make an LC meter and a frequency meter....
Several years ago, several colleagues in our company began to tinker with homemade PCB boards, and then we mastered the technology of homemade PCBs. At first, we used thermal transfer, but later we fo...
So why do we test small resistors, or just for fun? "Play" is a big theme. The main reason for measuring small resistors is large current. Small resistors have always been inseparable from large curre...
Do you often have to add brake fluid to your car's brakes? The fact that you need to pump out the brake fluid to make sure there is no gas in the brake fluid line may not be done by the car owner h...[Details]

1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]
Abstract: In order to realize wireless automatic alarm and monitoring of major safety places, based on the basic principle of pyroelectric infrared sensing, a detector for receiving infrared radia...[Details]
1 Overview
In the field of traditional lighting, the concepts and definitions of lamps and lamps are clear. Lamps and lamps have their own applicable product standards, supporting technical st...[Details]
The overall operating performance of an electric car depends first on its battery system and motor drive system. The drive system of an electric car is generally composed of three main parts: a con...[Details]
UDN2916LB is a two-phase stepper motor bipolar driver integrated circuit launched by SANKEN. It can drive dual-winding bipolar stepper motors and is particularly suitable for controlling dual-step ...[Details]
In the 1980s, breakthroughs were made in the design and production of small, low-power quartz metal halide lamps with precise dimensions. At the same time, with the acceleration of people's lives a...[Details]
