In embedded system development, driver design is a key factor affecting system performance, energy efficiency, and maintainability. Below is an in-depth analysis of three mainstream driver design techniques along with practical recommendations: 1. Polling Driver Technical Features: Blocking Design: The main program cannot perform other tasks while waiting for peripheral responses. Simple Implementation: Only requires … Read more

You won’t believe what I encountered this week! A well-established home appliance factory asked for my help to reduce energy consumption on their production line because their electricity costs were higher than the raw material costs. Upon inspection, I found that their equipment was running continuously even when not in production, just like someone leaving … Read more
Compiler Optimization Options: Analyzing GCC Optimization Parameters in C Language In C language development, the choice and use of the compiler are crucial. GCC (GNU Compiler Collection) is one of the most commonly used open-source compilers, providing a range of optimization options to improve the execution efficiency of generated code and reduce compilation time. This … Read more
