Function Overview In embedded systems, stack space is a memory area used to store temporary data such as function calls and local variables during program execution. Due to its fixed size and Last-In-First-Out (LIFO) operation characteristics, stack overflow can easily occur when recursive calls are too deep or too many local resources are dynamically allocated. This can not only cause program crashes but may also lead to unpredictable behavior of the entire system. To effectively prevent such issues, we have specially introduced a "Stack Overflow" warning mechanism in our smart meter design.   Warning Principle We set a safety threshold for each running task, which triggers a warning when the stack usage rate reaches 95%. This percentage is chosen based on an in-depth analysis of stack requirements under normal working conditions and considering the additional overhead in unexpected situations. Once the stack usage approaches the critical point, the system immediately records the event and saves relevant information through the built-in log system, such as occurrence time, current stack depth, call stack snapshot, etc., facilitating subsequent diagnosis and troubleshooting. Pre-delivery Testing Process Before each new meter model leaves the factory, we perform a series of rigorous tests to verify all key features, including but not limited to the "Stack Overflow" warning. These tests cover various scenarios from basic functions to extreme loads, ensuring that the equipment can work stably and reliably in real-world applications. User Value By integrating the "Stack Overflow" warning function, we not only enhance the stability of our products but also provide users with a more transparent and controllable operating environment. Even under complex and variable actual usage conditions, users can promptly understand potential risks and take necessary preventive measures with this feature, thus avoiding unnecessary losses. Additionally, detailed log records also help accelerate fault response, improve maintenance efficiency, and further increase customer satisfaction.
