Macro Definition Documentation

__VSF_FIFO_CLASS_IMPLEMENT

#define __VSF_FIFO_CLASS_IMPLEMENT

VSF_FIFO_CFG_PROTECT_LEVEL

#define VSF_FIFO_CFG_PROTECT_LEVEL   interrupt

Note

By default, the driver tries to make all APIs interrupt-safe, ! ! in the case when you want to disable it, ! please use following macro: ! #define VSF_FIFO_CFG_PROTECT_LEVEL none ! ! in the case when you want to use scheduler-safe, ! please use following macro: ! #define VSF_FIFO_CFG_PROTECT_LEVEL scheduler ! ! NOTE: This macro should be defined in vsf_usr_cfg.h

__vsf_fifo_protect

#define __vsf_fifo_protect   vsf_protect(VSF_FIFO_CFG_PROTECT_LEVEL)

__vsf_fifo_unprotect

#define __vsf_fifo_unprotect   vsf_unprotect(VSF_FIFO_CFG_PROTECT_LEVEL)
