The forum recently received an ST motor kit. I was the first to apply for a borrowed board for research. After receiving the board yesterday, I started researching in the evening and learned from othe...
Embedded systems are undoubtedly one of the hottest and most promising IT application areas. Embedded systems are used on some specific dedicated devices. Usually, the hardware resources (such as proc...
This is an example for the F5529 board, but since it includes USB, fatfs, Drivers, CTS, F5XX_F6XX_Core_Lib and other library files, I don't know how to build this project in IAR. For fatfs, it's ok be...
I would like to ask you a question. Assuming that the camera image acquisition has been realized on the development board, dynamic video can be seen or saved in bmp image format. Now we want to realiz...

introduction
In the discharge process of tokamak plasma physics, the study of rupture and sawtooth is of great significance. Rupture and sawtooth exist in most tokamaks. Rupture is a notew...[Details]
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]
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]
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]
With the advocacy and implementation of the government's Safe City Plan, the security market has increasingly higher requirements for the clarity of surveillance images. Imagine that after a case o...[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]
