If you have ever interacted with a computer using the command prompt or terminal, then you have used a Command Line Interface (CLI). In this article, we will explore how to create a basic CLI using Python’s <span>cmd</span> module. What is a CLI? A CLI allows you to interact with a computer by entering text … Read more
When developing C++ command line tools, we often need to handle various parameter parsing, option validation, and help information output. The traditional approach usually involves manually writing parsing logic or relying on <span>getopt</span> series functions. However, as the complexity of parameters increases, this method becomes error-prone and less intuitive. Thus, I started experimenting with some … Read more

Today, we proudly introduce a “Swiss Army Knife” level debugging tool tailored for embedded developers—letter-shell! It allows you to debug your microcontroller applications in real-time, flexibly, and efficiently, just … Read more
LCD (Liquid Crystal Display): also known as liquid crystal display. Widely used in embedded, mobile, and PC applications. This article mainly introduces common LCD classifications. 1 LCD classifications are as follows Divided into several categories based on signal type: TTL/LVDS/EDP/MIPI Classified by material (for TFT-LCD): TFT-TN/TFT-IPS/TFT-VA. Interface types include: RGB mode, SPI mode, MDDI mode, … Read more
Author:sigangjun blog.csdn.net/sigangjun/article/details/79071850 The full name of SPI is: Service Provider Interface. Most developers may not be familiar with it because it is aimed at vendors or plugins. There is a detailed introduction in the documentation of java.util.ServiceLoader. To summarize the idea of the Java SPI mechanism briefly: in our system, the various abstract modules often … Read more
Let’s talk about Xilinx’s MIPI solution. Here, we take the ordinary 7 series as the discussion object, while Xilinx’s high-end KU+/MPSOC+ already support MIPI interface IO directly. Due to the special nature of MIPI signals, low power consumption should be fully considered at the design stage. Therefore, the native signal levels of MIPI support both … Read more
MIPI is the most mainstream video transmission interface specification in the mobile field, and currently the most widely used are the MIPI DPHY and MIPI CPHY protocol families (there is also MIPI MPHY, which belongs to the high-speed Serdes category and is not as widely used). Among these, CSI-2 is mainly used for image input … Read more
MIPI CSI-2 (MIPI Camera Serial Interface 2) is the most widely used camera interface in the mobile and other markets. It is widely adopted for its ease of use and support for a wide range of high-performance applications, including 1080p, 4K, 8K, and higher video and high-resolution photography. It consists of protocol layer, application layer, … Read more
Taobao Store: Wolf FPGA A Detailed Tutorial for Zynq System Entry and Advancement The previous article introduced the development history, advantages and disadvantages, application fields, and development direction of MIPI interfaces in detail. Today, we will delve deeper into the content of the MIPI protocol. 1. Interface Definition The MIPI specification defines the interface into … Read more
