将宏赋给变量
// Host configuration structure
AshHostConfig ashHostConfig = ASH_HOST_CONFIG_DEFAULT;

结构体成员traceFlags就是调试开关，具体宏要在初始化时候写进ASH_HOST_CONFIG_DEFAULT即可！

// Bits in traceFlags to enable various host trace outputs
#define TRACE_FRAMES_BASIC        1   /*!< frames sent and received */
#define TRACE_FRAMES_VERBOSE      2   /*!< basic frames + internal variables */
#define TRACE_EVENTS              4   /*!< events */
#define TRACE_EZSP                8   /*!< EZSP commands, responses and callbacks */
#define TRACE_EZSP_VERBOSE        16  /*!< additional EZSP information */

#define ashReadConfig(member) \
