I have been self-studying microcontrollers for almost a month. I usually read books and look at programming examples. Recently, I feel that I have mastered the basic sentences. However, when I encount...
The current product uses stm32+ucos+ucGUI. As the company develops, we may face the issue of licenses in the future. We are going to change the OS to freeRTOS or RTT or eCos, and we are also going to ...
[i=s]This post was last edited by grove_armweak on 2019-11-29 23:06[/i]1. Is 1W enough for R1 in the picture?2. What is the best power for R3, R4, and R5 respectively?3. Can 7407 be omitted in the fig...
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();
1. Limited secondary filtering
/* A value can be adjust...[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]
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]
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]
In recent years, lighting has become an important area that countries around the world are targeting to promote energy conservation and environmental protection. According to statistics, about 20% ...[Details]
Aromatic gases are widely present in food, medicine, cosmetics and various daily chemical products, such as snacks, liquor, spices, Chinese herbal medicines, plasters, perfumes, soaps, shampoos, et...[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]
With concerns about the growing energy crisis, motor efficiency has become an important and timely topic. This is because motors use 63% to 70% of the electricity produced in the United States and ...[Details]
Abstract: Aiming at the needs of coal-rock acoustic emission signal monitoring system, a data acquisition circuit with 24-bit resolution and 16-channel synchronous data acquisition function is desi...[Details]
Abstract: With the development and construction of BeiDou II system, China will shift from the situation dominated by GPS to the situation dominated by BeiDou II global navigation system independen...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
Temperature compensated quartz crystal oscillator (TCXO) is widely used as a high-precision frequency source in communication systems, radar navigation systems, precision measurement and control sy...[Details]
Fruit planting is an important part of China's agricultural development, and fruit tree pest control operations are becoming more and more important. At present, the overall level of pesticide applica...[Details]
Measurement compatibility
It is very important to ensure the compatibility between the pressure sensor and its actual application. Before making a pressure sensor selection, the fo...[Details]
