Recently, during a code review, I noticed that many colleagues’ coding practices were teetering on the edge of risk, with one of the most glaring issues being the arbitrary placement of local variable definitions. For seasoned C programmers, most have developed the habit of “defining variables at the beginning of a statement block”. I vaguely … Read more

Introduction In embedded development, have you ever encountered a scenario where the value of a global variable suddenly changes? The interrupt service routine has modified it, yet the main program continues to read the old value. Even more frustrating, these issues are often difficult to reproduce, making debugging feel like “catching ghosts.” The root cause … Read more
