My initial idea is to use an AT89S51 chip, add A/D conversion and D/A conversion, add an amplifier and a speaker, and a digital display. But I don't know how to do the voice recorder part. I would lik...
This issue mainly describes the use of stm32GPIO, and makes a GPIO example (flowing light). You can download it in the attachment if you need it.The test on Smurf stm32 passed....
My new computer arrived today. When I bought it, there were 512+1T hard drives and 512 only hard drives. Since I have a lot of hard drives and I plan to install them myself, I didn't choose the one wi...
The TI development board onboard emulator is very convenient. What I want to ask is whether the CPLD can be removed, because I still need to program the CPLD, which is very troublesome. Please answer ...
For PCB failure, we need to use some common failure analysis techniques to ensure the quality and reliability of PCB during manufacturing. For this purpose, the author summarizes ten techniques for PC...
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]
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();

introduction
Since the beginning of the 21st century, the world of information has changed rapidly. Maybe a high-tech product will be released today and a better similar product will be releas...[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]
Floating-point digital signal processing has become a constant requirement for precision technology, often in applications requiring high accuracy in areas such as aviation, industrial machinery, a...[Details]
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]
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]
1 Introduction
Solar street lights are mainly composed of four parts: solar photovoltaic cell components, batteries, charge and discharge controllers, and lighting fixtures. The bo...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[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]
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]
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]
Overview
In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[Details]
