The power consumption of terminal products is also increasing, so standby time has become one of the key performance indicators of the product. As portable terminal equipment is limited by size, it is...
I've been debugging an LCD recently, and my problem is that after my LCD starts up normally, there's a very thin white line at the top that looks like a line under the taskbar underground going up and...
class a { private: typedef void (CALLBACK * ONSERIALREAD)(CWnd *,BYTE * Buf, int bufLen); public: ONSERIALREAD m_OnSerialRead; } How to implement this callback function?...
The program is as follows: #include reg52.h sbit P0_0=P0^0; unsigned char times; void main() { times=0; TH2=60;TL2=176;//Initial value of count RCAP2H=60;RCAP2L=176;//Reload initial value EA=1;//Open ...
[size=4]In embedded software development, such as microcontroller programs, we will definitely write a large infinite loop program, that is, polling the IO port. Usually, [/size] [size=4] [/size] [siz...
Calibrators are widely used in university experiments. Among them, there are two experiments in nuclear physics experiments in modern physics experiments (GM counter and β absorption) that require ...[Details]
Although improper medical device product design is not always associated with medical device-related errors. Studies of users have shown that lack of adequate training accounts for 70% to 90% of suc...[Details]
The U.S. Food and Drug Administration (FDA) points out that home health care is the fastest growing area in the medical device industry. Driven by the increase in average life expectancy, the increasi...[Details]
Ultrasound systems are among the most sophisticated and complex signal processing instruments in widespread use today. Like any complex instrument, there are many trade-offs to be made in implement...[Details]
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]
For more than 10 years, analog-to-digital converters (ADCs) have been widely used in industrial process control, medical instruments, communication systems, radar and other products as a booster of in...[Details]
A biped robot joint constructed by pneumatic artificial muscles is introduced. The joint uses the flexible characteristics of pneumatic artificial muscles to effectively control the impact of the la...[Details]
This issue will briefly introduce the test related to spectrum - occupied bandwidth.
Definition: Occupied bandwidth refers to the bandwidth corresponding to 99% of the total transmitted power, cent...[Details]
The overcurrent and overheating coordinated protection technology implemented by polymer positive temperature coefficient devices (PPTC) can protect motors, controllers and electronic components in...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
In the issue of ensuring the safety of drivers and pedestrians, the proportion of electronic technology has increased. According to the survey, 80% to 90% of traffic accidents are caused by driver...[Details]
Power Integrations (PI) has introduced three charger/adapter reference designs using its new LinkSwitch-II series of AC-DC switching power conversion ICs. The new LinkSwitch-II devices use high-pre...[Details]
1. What is fading?
In terms of scope, fading can be roughly divided into three types: large area fading, small area fading and indoor fading. As shown in Figure 1, large area fading refers t...[Details]
A correct circuit design cannot be manufactured 100% correctly when it is taken to the factory for manufacturing. It will always be affected by various uncertainties, such as deviations in manufact...[Details]
