How to Achieve Clear Architectural Design in Embedded Systems?

In embedded system development, the visualization and documentation of software architecture are often overlooked, leading to difficulties in project maintenance and chaotic team collaboration. The C4 model created by Simon Brown (Context, Containers, Components, Code) clearly presents software architecture in a layered and progressive manner, making it particularly suitable for resource-constrained and increasingly complex embedded … Read more

Development of Printed Circuit Boards (PCBs) and Multilayer Board Manufacturing Technology

Click the blue text to follow us Printed Circuit Boards In the early 20th century, Paul Eisler first proposed the concept of “printed circuits” and developed the world’s first printed circuit board (PCB). As the most widely used substrate in secondary electronic packaging technology, it is a substrate covered with single or multiple layers of … Read more

PCB Layout Routing: Similarities with Life

PCB Layout Routing: Similarities with Life

1. Layout should come before routing; no matter how detailed the routing is, if the layout fails, it is all in vain. Life is similar; one must have ideals and long-term plans. 2. If one only seeks comfort in early routing, later detours will lead to dead ends. Life is the same: endure hardships for … Read more

Reflections on Principles of Embedded Software Design

There are many theories regarding object-oriented development that can also be referenced for embedded C software development. My knowledge is limited, and this is merely a starting point for discussion. 1 Design Principles SRP Single Responsibility Principle: Each function or module should have only one responsibility, and only one reason for it to change. OCP … Read more
