In embedded system development, as project complexity increases and cross-platform requirements grow, the bare-metal programming approach of “write whatever comes to mind” is becoming inadequate. Adopting a layered architecture is key to ensuring code maintainability, portability, and testability.Among these, the division and collaboration between the hardware abstraction layer and the driver layer is the core … Read more
When understanding robots solely through news and short videos, one often experiences a strong contrast: on one side, there are high-energy robots capable of precise punches and agile “sneak attacks” on humans, while on the other side, there are robots that awkwardly “roll around” on the ground. Where does this huge disparity come from? It … Read more

1. What is an Interrupt? It interrupts the normal execution of the CPU’s program to handle an urgent program, and after processing, it returns to the original paused program to continue execution. As shown in the figure below, for example, I am doing homework, and suddenly feel thirsty, so I go to drink water. The … Read more
Embedded systems are ubiquitous—from smartphones and smart homes to automotive electronics and industrial control, they act as the “invisible brain” driving modern life. However, it is often said in the industry: “Embedded development is as difficult as climbing to the sky!” Why is it so hard? Is it due to high technical barriers, or is … Read more
