I wrote an emwin program as follows: //BUTTON_SetText(hButton4,"力值检验定"); BUTTON_SetText(hButton4,"力检验定"); Button 4 displays two Chinese characters fine, but the compilation fails when it displays thre...
I am making a GPRS water level collector recently, using a single-chip microcomputer + ultrasonic + sim300 module. The upper and lower computer programs are all ready, and they can all run normally. T...
Because the power supply is not clean and has several mV of high noise, it is a narrow pulse of about 100MHz when magnified, so an LC-PI filter circuit is added. However, because the transient current...
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]
Sailing is gaining more and more attention. How to use modern technology to assist training and improve competition results is particularly important. Considering the real-time data collection in t...[Details]
Remote keyless entry (RKE) systems have become popular with users, with more than 80% of new cars in North America and more than 70% in Europe equipped with RKE systems. In addition to the obvious ...[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]
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]
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]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[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: 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]
Since AC mains power may experience power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations during supply, these factors will affect the continuous ...[Details]
Introduction
Nowadays, people pay more and more attention to the security alarm system, and people have higher and higher requirements for the functions and performance of the alarm. This paper prop...[Details]
