定时器

一、函数

os_timer_create

os_timer_id os_timer_create(const char *name, void (*func)(void *parameter), void *parameter, os_tick_t time, os_uint8_t flag);

功能: 创建定时器
参数:

• name: 定时器名称
• func: 超时回调函数
• parameter: 回调参数
• time: 超时时间
• flag: 标志
  • OS_TIMER_FLAG_ONE_SHOT: 单次触发
  • OS_TIMER_FLAG_PERIODIC: 周期性触发

os_timer_delete

os_err_t os_timer_delete(os_timer_id timer);

功能: 删除定时器

---

os_timer_start

os_err_t os_timer_start(os_timer_id timer);

功能: 启动定时器

os_timer_stop

os_err_t os_timer_stop(os_timer_id timer);

功能: 停止定时器

os_timer_set_time

os_err_t os_timer_set_time(os_timer_id timer, os_tick_t time);

功能: 设置超时时间

os_timer_get_time

os_tick_t os_timer_get_time(os_timer_id timer);

功能: 获取超时时间

os_timer_get_remaining_time

os_tick_t os_timer_get_remaining_time(os_timer_id timer);

功能: 获取剩余时间

---

OS_TIMER_DEFINE

#define OS_TIMER_DEFINE(name) os_timer_dummy_t name

功能: 静态定义定时器

os_timer_init

os_err_t os_timer_init(os_timer_id timer, const char *name, void (*func)(void *parameter), void *parameter, os_tick_t time, os_uint8_t flag);

功能: 初始化静态定时器

os_timer_deinit

os_err_t os_timer_deinit(os_timer_id timer);

功能: 反初始化静态定时器

二、结构体

struct dummy_timer_active_node
{
#ifdef OS_USING_HASH_BUCKET_TIMER
    os_list_node_t active_list_dummy;
    uint8_t        info_dummy;
#endif

#if OS_TIMER_PERIODIC_COMPENSATE
    os_tick_t timeout_tick_dummy;
#endif
    uint8_t flag_dummy;
};
typedef struct dummy_timer_active_node dummy_timer_active_node_t;

struct dummy_timer
{
    void (*timeout_func_dummy)(void *timeout_param); /* Timeout function. */
    void     *parameter_dummy;                       /* Timeout function's parameter. */
    os_tick_t init_ticks_dummy;                      /* Timer timeout tick. */
    os_tick_t round_ticks_dummy;                     /* Timeout tick remaining. */
#ifdef OS_USING_HASH_BUCKET_TIMER
    uint32_t index_dummy;
#endif
    os_list_node_t            list_dummy;
    dummy_timer_active_node_t active_node_dummy;
    char                      name_dummy[OS_NAME_MAX + 1];
};
typedef struct dummy_timer dummy_timer_t;
