Note

By default, the driver tries to make all APIs thread-safe, in the ! case when you want to disable it, please use following macro to ! disable it: ! ! #define SYSTICK_ATOM_CODE(...) \ ! for (int VSF_MCONNECT2(_, LINE) =1;VSF_MCONNECT2(___, LINE)–;) ! ! ! NOTE: This macro should be defined in app_cfg.h or vsf_cfg.h
