Course Address:https://www.cc4e.com/ This lesson, From Python to C, mainly teaches how to quickly switch from Python to C language. C is the mother of high-level programming languages, and Python itself is written in C. Many programming languages borrow syntax from C. The instructor does not want this to be your first language course; rather, they … Read more
In embedded development, as projects progress, issues such as reinventing the wheel, code dispersion, and maintenance difficulties are common. How to systematically build your own general-purpose function library (“library of wheels”) that can be efficiently reused and continuously evolved is a challenge every developer faces. Benefits of Building a Function Library • Reduce Redundant Work: … Read more
Overview of 8051 Microcontroller and 4-bit LCD Interface This example explains how to connect a 16×2 LCD to the 8051 microcontroller in 4-bit mode, thereby reducing the number of microcontroller pins required. It covers software tools such as Keil uVision (for coding) and Proteus (for simulation). The code example demonstrates how to send commands to … Read more
In the field of embedded application development, OpenCV has become the preferred tool for developers handling computer vision tasks due to its rich functionality. Buildroot provides a convenient embedded system build environment, with the default integrated version of OpenCV being 4.5.4. However, in practical applications, different projects often have specific requirements regarding functionality and performance, … Read more

The three modes are as follows: BOOT1 BOOT0 Startup Mode Description X 0 Main Flash Memory Main Flash Memory is selected as the startup area 0 1 System Memory System Memory is selected as … Read more
RFID (Radio Frequency Identification) is a non-contact automatic identification technology that uses radio frequency signals to automatically identify target objects and obtain relevant data. It is widely used in logistics, retail, transportation, healthcare, and many other fields. The following is a detailed introduction from the aspects of technical principles, components, application scenarios, and advantages and … Read more
This is hard to say, as there are no organizations that specifically track this. However, the number of MCU positions is increasing because MCUs are becoming more powerful, capable of performing tasks that were previously only possible with Linux, gradually encroaching on Linux’s market. However, MCUs typically have a single core, and running Linux on … Read more
