It is known that the resonant frequency of a quartz crystal is about 5MHz (with a deviation of about tens of Hz). If we want to test its resonant frequency more accurately, can we use it as a crystal ...
Are there any seniors who are familiar with Beidou chips and GPS chips who can recommend some relatively stable, low-power, and low-voltage Beidou chips and GPS chips?...
A few questions: 1. Is the prospect of embedded system good? How is the salary? 2. Doesn't embedded system engineer have a bottleneck at 35 years old? 3. I am a student, I want to know how much the tr...
1. Introduction
RFID (radio frequency identification) is a non-contact automatic identification technology that emerged in the 1990s. It uses the characteristics of radio frequency signal prop...[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]

At present, the research on micron and nanotechnology is very active, which has led to the rapid development of microtechnology and micro-mechanical electronic system (MEMS) t...[Details]
Every time I go home and walk up the stairs, I am always scared. The corridor lights are often broken, and no one changes the bulbs, or they are not smart enough and need to be operated manually. E...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
The capacity of a battery depends on the amount of charge and discharge, in addition to some factors of the battery itself. Obviously, if the charge and discharge of the battery can be recorded all...[Details]
Multimedia processors are often the most power-hungry devices in portable electronic devices. Common ways to reduce CPU power requirements are to reduce clock frequency or operating voltage, but th...[Details]
