AWorks Programming: Memory Management in Embedded C Language

The C/C++ language differs from other languages in that it requires developers to manage memory resources themselves. Improper use of dynamic memory can easily lead to segmentation faults or memory leaks. In particular, memory leaks are often discovered only after the program has been running for a while, making it difficult for developers to locate … Read more

In-Depth Discussion on Embedded C Programming: Have You Libraryed?

Libraries are powerful tools! If a device program is perfectly libraryed, it means: 1. All engineers spend minimal effort when porting or creating the device driver. 2. As the number of users increases, it becomes more stable through extensive testing, evolving into a well-deserved public code. 3. The external interface of the library (function names … Read more
