Extracting Reusable Driver Layers from STM32CubeMX Generated Code — HAL/LL Encapsulation Practices

In embedded project development, STM32CubeMX is widely used for its visual configuration and one-click generation of initialization code. However, as project complexity increases, we gradually find that the structure of the code generated by CubeMX, while convenient for beginners, is not conducive to code reuse and cross-project migration. To address this issue, extracting and encapsulating … Read more
