The project requires a rechargeable battery with 220V AC input and 5V 5A output (preferably with adjustable voltage). The size and weight should not be too large and the battery life should be about o...
Hello everyone! I have a question that is a bit high-level, haha. China imported about 230 billion US dollars of integrated circuits in 2013 and about 240 billion US dollars in 2014. I would like to k...
Why does my program stop running after a while or stops at a distance after it is downloaded to the board?
#include stm32f10x_lib.h #include "sys.h" #include "usart.h" #include "delay.h" #include "led...

Fetal monitoring is an important means to ensure the safety of perinatal mothers and fetuses and achieve eugenics. Intelligent fetal monitoring is a monitoring method that analyzes the health stat...[Details]
Industrial control
often requires multi-channel fault detection and multi-channel command control (this multi-task setting is very common). A single CPU chip is difficult to directly complete ...[Details]
1 Introduction
Intelligent software agents are software programs that can perform specific tasks for users, have a certain degree of intelligence, can autonomously perform some tasks, and ...[Details]
Abstract: By controlling the supply voltage of the radio frequency (RF) power amplifier (PA) in a CDMA/WCDMA cellular phone, the PA efficiency can be improved, heat generation can be reduced, and t...[Details]
l Introduction
Traditional human-computer communication is achieved through keyboard or mouse. The speed of information exchange is relatively slow, and the operator is required to have certain...[Details]
Abstract:
Under high dynamic conditions, combined with GEC's twelve-channel correlator GP2021, this paper discusses the structural design of GPS receivers and the key technologies inv...[Details]
Nowadays, the phenomenon of using cloned taxis and trucks for operation is becoming more and more serious. The so-called cloned car is one or several unlicensed vehicles that are used to copy anoth...[Details]
Abstract: In many SCART applications, due to the complex signal switching requirements, dedicated ICs are usually used to implement SCART connections. This will bring cost pressure to single SCART ...[Details]
