I wrote a socket client program in C# and C++ and ran it on wince. Why, when connected to the server, the newly launched client causes the previously launched client to lose connection? The server has...
When I connect R16, even if I remove the chip MOC3041, the bidirectional thyristor is still conducting, which means that the thyristor is no longer controlled. When R16 is not connected, even if P37 g...
I am a newbie. Today I got a project to take over. One of the sub-projects is a static libaray project, but the generated file is a .a file. Isn't it usually a .lib file? What is a .a file?...

Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]
In the previous series, we have listed some basic knowledge of C language in Tables 1 to 3. We hope that beginners can strengthen their memory of the above tables and gradually learn to use them wh...[Details]
1 Introduction
Intelligent control instruments are one of the most commonly used controllers in industrial control. They are mainly aimed at a specific parameter (such as pressure, tempera...[Details]
This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]
Printed circuit boards ( PCBs
)
are used in most electrical products
. If a PCB has low
insulation resistance
(IR), the performance of the circuits on the PCB will be greatly reduced...[Details]
We know that the inverter consists of two parts: the main circuit and the control circuit. Due to the nonlinearity of the main circuit (switching action), the inverter itself is a source of harmoni...[Details]
With the widespread application of new services and technologies in the communications industry, the scale and capacity of operators' network construction are getting larger and larger, and the ris...[Details]
The serial interface real-time clock chip DS1302 launched by Dallas Company in the United States can trickle charge the backup battery of the clock chip. Due to the main features of the chip such a...[Details]

Electric bicycles have long been a means of transportation for lower-income groups due to their affordability. The largest concentrated expense in the use of electric vehicles is the cost of replac...[Details]
At present, with the diversification of portable products and the almost harsh requirements for audio and video parts, the power consumption requirements of the whole machine have been raised to a ...[Details]
The power consumption of a switching power supply includes fixed losses caused by parasitic resistances such as semiconductor switches, magnetic components, and wiring, as well as switching losses ...[Details]
Currently, high-frequency and high-efficiency DCDC converters are increasingly used in automotive electronic systems.
High switching frequency can use smaller power inductors and output filter...[Details]
It should be understood as follows: DC-DC means direct current to direct current (conversion of different DC power values). Anything that meets this definition can be called a DC-DC converter, incl...[Details]
