Dear experts, I mainly design and develop the application layer. I have no plans to directly develop wireless low-level chips for the time being. I plan to purchase ready-made wireless modules (UHF, Z...
I know that sendto is mainly about parameters, and I can use it, but sendto requires a char pointer, so I defined a char buffer [1024]; when assigning values, buffer [number] = number; this works, and...
I want to ask if I can observe the pulse signal with an analog oscilloscope. This pulse signal is similar to a switch signal, electromagnetically triggered. The site conditions are limited, and there ...
This morning I used IAR to debug the co-program. At the beginning I downloaded an incorrect program. After correcting it, I could not download it anymore. The above prompt is attached. I have been deb...
It's the second day of the Spring Festival, I thought it would get warmer, but it's snowing now. I just went out and saw a centimeter of snow. I remember when I got home and checked the weather foreca...

1 The significance of using RTOS on MSP430
It is understandable that it is meaningless to use RTOS on MSP430. Because the hardware resources of MSP430 are limited (for exampl...[Details]
1. Introduction
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]
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]
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]
Analog engineers have traditionally struggled with complexity when designing power supplies that required multiple outputs, dynamic load sharing, hot-swap, or extensive fault-handling capabilities....[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]
The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[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]
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]
