I believe that such a bug can be made by even the most skilled programmers. Come and see the bug that the author made. First, the author wanted to use a piece of code to create a file. If a filename is provided, it creates a real file; if not, it calls tmpfile() to create … Read more
Embedded development is the core technology field that connects hardware and software, involving full-link development from low-level chips to high-level applications. Its knowledge system covers multiple dimensions such as hardware design, operating systems, driver development, and communication protocols. This article will systematically outline the knowledge framework of embedded development and provide learning paths and resource … Read more
Recently, while debugging an FPGA for video capture and playback, I utilized the MIPI CSI-2 TX Subsystem (2.2) IP. Debugging this board was quite challenging, and I encountered numerous pitfalls, especially since it was my first time working with video interfaces and I was unable to identify the issues. I will document the problems encountered … Read more
Arduino programming is a simplified version based on C/C++ language, allowing code to be written and uploaded to the Arduino development board through an Integrated Development Environment (IDE) to control external devices. Its core features are “low threshold and high extensibility”, enabling quick entry even without hardware knowledge.Currently, many programming robots in China are based … Read more
In the field of industrial automation, the stability and reliability of systems are crucial. Today, I would like to share an advanced topic – PLC fault injection techniques. This technology helps us identify potential issues early in the system development phase, thereby improving system robustness. What is Fault Injection? Fault injection is essentially the intentional … Read more
Hello, automation friends! Recently, I received a call from the workshop saying that the robotic arm on the assembly line was moving out of sync and started to “dance” after running for an hour. I rushed over and found that it was a typical case of improper PLC motion control parameter settings! This is no … Read more

CANopen is an application layer protocol based on the CAN bus. Porting it to the target platform generally requires the following steps: 1.Hardware Preparation â—¦Ensure that the target microcontroller or microprocessor has a CAN controller. If there is no built-in CAN controller, an external CAN controller chip (such as SJA1000, etc.) may be required, and … Read more
