In an NPN transistor, the base current is only generated by the recombination of electrons diffused from the emitter to the base and holes in the base....
When debugging, I found that the program often ran into the HardFaultException() {while(1);} function! Because K9f1G08 is a large page nand, the defined buffers are both 2k for receiving and sending! ...

At present, the sensors for measuring wind speed mainly adopt thermal, ultrasonic, impeller and pipeline pressure difference methods. The thermal method is that the sensor element generates heat when ...
At present, the development of wireless power supply technology for electric vehicles (EVs) is becoming more and more active. In 2012, Volvo of Sweden established Volvo Technology Japan in Tokyo as...[Details]
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
Automotive applications are particularly sensitive to EMI events, which are unavoidable in a noisy electrical environment consisting of a central battery, bundled wiring harnesses, various inductiv...[Details]
In order to highlight the concept of "energy saving and environmental protection" of intelligent buildings, solar street lights are designed for intelligent communities. The inclination and capacit...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[Details]
Vertical cavity surface emitting lasers (VCSELs) are gradually replacing traditional edge emitting lasers, especially in low bandwidth and short-distance communication systems where cost factors ar...[Details]
Since the No. 4 blast furnace of Handan Iron and Steel was put into operation in 1993, its external equipment has been seriously aged, and the original PLC control system TDC3000 of the hot blast furn...[Details]
Nippon Electric Works and Volvo Technology Japan have developed a wireless power supply system for electric vehicles (EVs). Using this system, the two companies have successfully conducted an exper...[Details]
System Overview
The system consists of a signal preprocessing circuit, a single-chip computer AT89C2051, a systematic LED display module, a serial port data storage circuit and system software...[Details]

Wireless Sensor Network (WSN) monitors the target by deploying a large number of sensor nodes in the target area. WSN realizes the positioning and tracking of the target, determi...[Details]
One in five car failures are caused by batteries, a problem that will become more serious in the coming years as electric-by-wire, start/stop engine management and hybrid (electric/gas) vehicles be...[Details]
The production process of lithium batteries does not mention the previous processes such as material preparation, winding, liquid injection, and packaging, but only talks about the final formation ...[Details]
DCDC means DC to DC (conversion of different DC power values). Anything that meets this definition can be called a DCDC converter. Specifically, it means converting the input DC into AC through a s...[Details]
