I made a zigbee module and received bytes from the serial port. I found that if too many bytes are transmitted (139 bytes at a time), 20 bytes will be lost. I reduced the bytes and sent them again. Wh...
A few days ago, a friend asked me that there are two versions of 18b20 in the market, c3 and c4 (I am not well-informed and have never heard of them). He originally used the c3 version, and later his ...
Hey guys, after the ZigBee coordinator goes offline, the nodes will keep searching for the network, so the battery-powered nodes will run out of power very quickly. How can we save power and search fo...
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]

This design was made for participating in an electronic design competition. It effectively solved the problem of the operation and control of an electric car on a seesaw. The s...[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]
With the advent of increasingly powerful processors, image sensors, memory, and other semiconductor devices, as well as the algorithms that enable them, computer vision can be implemented in a wide...[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]
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]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[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]
