There are many devices on the market that provide the ability to monitor the home environment from a central interface. In this article, we will DIY a set of such monitoring equipment. To do this, we will use the B+ model Raspberry Pi development board and the official Raspberry Pi
libmodbus We have introduced it many times in our public account and application notes, regarding its download, compilation, installation, configuration, cross-compilation, etc. If you are unclear, you can refer to previous articles in our public account.
Classic example demonstration of Modbus TCP/IP
Today I recommend: libModbus
This article mainly involves testing the Modbus RTU mode. Regarding Modbus TCP/IP, it has also been pushed in previous articles. Because the hardware serial port and Bluetooth of the Raspberry Pi 3 are shared, some configurations and

Abstract
This article mainly documents the technologies involved in my project, including: .NET IoT, .NET Web, .NET MAUI, and the framework used is the latest .NET 7.
I developed and tested it using Raspberry Pi Zero 2 W (ubuntu-22.04), but the .NET IoT library also has a community submission by Zhang Gaoxing for Orange Pi GPIO pin mapping, with corresponding drivers for Orange Pi models available at https://github.com/dotnet/iot/tree/main/src/devices/Gpio/Drivers.
Those who are on a budget can try modifying the code for Orange Pi
The screenshot tool on a computer seems like a basic tool that should be pre-installed on any operating system. However, there is nothing installed by default on the Raspberry Pi OS, so you have to find one yourself.
There are many screenshot tools in the Linux environment, but only a few are actually useful. There are many bugs in related software under the Wayland environment. Flameshot is good, but I have encountered
With the powerful AI accelerator module, the Raspberry Pi camera module and AI kit bring exciting possibilities for computer vision and machine learning. The versatility of the Raspberry Pi platform combined with its AI capabilities opens up a whole new world of possibilities for innovative smart projects. From creative experiments to practical applications like smart dispensing machines, makers are leveraging the potential of this kit to advance AI. In this feature, we will explore some outstanding projects that we hope
In the world of Raspberry Pi, the camera module has always been a focal point. With the release of the new generation of Picamera2, users are greeted with an exciting moment. Picamera2 is a new camera interface based on libcamera, providing developers and makers with a simpler and more flexible Python API, making it an important tool for image processing and video recording. This article will detail the main features, installation methods, and application examples of Picamera2, helping you get

First, the conclusion: microcontrollers are more suitable for commercial products, while Raspberry Pi and Arduino are better for learning skills.
Next, I will introduce their differences:
1. Raspberry Pi
Raspberry Pi and Arduino are both open-source hardware platforms, but they
Arduino has a rich set of external interfaces, and the biggest difference from Raspberry Pi's IO ports is that Arduino has analog input interfaces that can measure analog values on IO ports. The communication scheme between Arduino and Raspberry Pi via serial (Serial) generally has two methods: one is through Raspberry Pi GPIO serial communication, and the second is through USB serial communication.
Clearly, the USB serial communication between Arduino and Raspberry
You have a Raspberry Pi running Raspberry Pi OS, which used to be called Raspbian, and you surely know that it is a fantastic small computer with a great operating system that includes everything a beginner might want. However, once you
Installed Raspberry Pi 5 OS (64-bit recommended system)
Note this is not a slim version, nor is it the full recommended software version, and it is not a 32-bit version
The system size is about 1.2GB
Desktop version interface
For the convenience of the desktop and testing desktop memory usage, I ultimately chose the desktop version
Only installed the desktop version, with no software running, memory usage is about 500M, which is
