Sometimes I want to check out the posts I participated in before, but it’s not easy to find them! I can just add this function to the bottom of my posts. I wonder if the website has considered this as...
Recently, the project needs to use mqtt on stm32. I searched on Baidu and found that there is still very little information on the Internet, although there are several relevant materials. After downlo...
[b][size=4]Recently, a new project has started. I worked overtime for 7 days during the National Day holiday. I sent out the boards I had drawn before. In order to save money, I put together 6 boards....
I was reading the IIC section in Professor Xia Yuwen's book, which describes how the data on the SDA data line is stored in the register. The data is valid when SCL is at a high level (that is, SDA mu...
1: I am using C6424, which is in little-endian mode. I saw that the CCS configuration platform can be set to big-endian mode, so I set it to big-endian mode, and everything can be compiled. Finally, w...
Does anyone have a small signal model for buck dual-loop control? The outer loop voltage loop, the inner loop current loop, and the average current model?...
The rapid development of the Internet has realized high-speed information transmission and resource sharing, greatly facilitating people's lives. Embedded systems are widely used in various electr...[Details]
Microchip's PIC18F46J50 is a low-power, high-performance 8-bit USB microcontroller (MCU) using nanoWatt XLP technology. The current in deep sleep mode can be as low as 13nA, the operating voltage i...[Details]
This article discusses how to wake up a touch-sensitive device such as a tablet without touching the device, using basic gesture recognition and novel proximity sensors. The article discusses the p...[Details]
introduction
Solar cells and LED lighting are typical applications of new energy and energy-saving and efficient technologies. Solar LED lighting uses solar cells to convert solar energy...[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]
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]
Two simple circuits are implemented to drive two LEDs from a battery powered microprocessor.
This design is based on a circuit that uses three resistors and a microprocessor I/O pin as an input h...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
Microcalorimetry
is used to determine energy relationships. Microcalorimetry techniques are often required when performing calorimetric experiments with small sample sizes or slow heating rat...[Details]
General LED lighting has a current limiting resistor in the driving circuit, and the power consumed by the resistor has nothing to do with the LED light emission. In order to improve efficiency, a...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[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]
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]
Introduction
As the country increases its efforts to control the atmospheric environment, motorcycle emission regulations will become stricter year by year, and motorcycles that do not meet the...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
