本章介绍对tkl_nbiot_psm.c的接口相关适配

  • 平台psm配置相关

    • Code: Select all

      /**
 * @brief Set config about the paltform
 *
 * @return OPERATE_RET OPRT_OK: success others: fail
 */
OPERATE_RET tkl_nbiot_psm_plat_config(VOID)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      对于PSM相关初始化无特殊操作，直接返回OPRT_OK

    • Code: Select all

      /**
 * @brief Regist the PSM sleep notify cb
 *
 * @param cb notify callback function
 * @return OPERATE_RET OPRT_OK: success others: fail
 */
OPERATE_RET tkl_nbiot_psm_sleep_notify_reg(TKL_NB_PSM_NOTIFY_CB_T cb)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      系统睡眠事件通知回调注册(设备睡眠前需要将各种睡眠类型通过回调cb通知SDK)

    • Code: Select all

      /**
 * @brief Specify a pin for wakeup trigger
 *
 * @param pin_num  @ref TKL_GPIO_NAME_E
 * @param wakeup_cb call back funtion
 * @return OPERATE_RET OPRT_OK: success others: failed
 */
OPERATE_RET tkl_nbiot_psm_wakeup_pin_cfg(INT_T pin_num, TKL_NB_WAKEUP_CB wakeup_cb)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      PSM外部硬件唤醒脚及唤醒后回调函数注册

  • 睡眠锁操作

    • Code: Select all

      /**
 * @brief Create a psm manager lock
 *
 * @param lock_name name of the lock
 * @param handle sleeplock handle
 * @return OPERATE_RET OPRT_OK: success others: fail
 */
OPERATE_RET tkl_nbiot_psm_create_sleeplock(CONST PCHAR_T lock_name, UCHAR_T *handle)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      创建睡眠锁

    • Code: Select all

      /**
 * @brief Acquire the sleeplock, keep awake
 *
 * @param handle sleeplock handle
 * @return OPERATE_RET OPRT_OK: success others: fail
 */
OPERATE_RET tkl_nbiot_psm_acquire_sleeplock(UCHAR_T handle)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      睡眠锁定(禁止系统进入睡眠)

    • Code: Select all

      /**
 * @brief Release the sleeplock, allow psm
 *
 * @param handle sleeplock handle
 * @return OPERATE_RET OPRT_OK: success others: fail
 */
OPERATE_RET tkl_nbiot_psm_release_sleeplock(UCHAR_T handle)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      睡眠锁释放(允许系统进入睡眠)

  • 睡眠操作相关

    • Code: Select all

      /**
 * @brief Force enter psm mode
 *
 * @return VOID
 */
VOID tkl_nbiot_psm_force_sleep(VOID)
{
    // --- BEGIN: user implements ---
    return ;
    // --- END: user implements ---
}

      强制睡眠(立即进入睡眠)

    • Code: Select all

      /**
 * @brief Get the power on reason
 *
 * @param result powerson reason
 * @return OPERATE_RET OPRT_OK: success others: fail
 */
OPERATE_RET tkl_nbiot_psm_get_poweron_result(TKL_NB_POWER_ON_RESULT_E *result)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      获取系统从何种状态醒来(上电启动/睡眠/系统复位/看门狗复位等)

    • Code: Select all

      /**
 * @brief Get the wake up reason
 *
 * @param src wakeup reason reason
 * @return OPERATE_RET OPRT_OK: success others: fail
 */
OPERATE_RET tkl_nbiot_psm_get_wakeup_source(TKL_NB_WAKEUP_SOURCE_E *src)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      获取系统被何种唤醒源唤醒(上电唤醒/RTC定时唤醒/PSM按键唤醒)

  • 睡眠定时器相关操作

    • Code: Select all

      /**
 * @brief Create rtc timer
 *
 * @param time_period_sec time period of the timer
 * @param is_periodic if the timer is perodic
 * @param cb timer callback
 * @return OPERATE_RET OPRT_OK: success others: failed
 */
OPERATE_RET tkl_nbiot_psm_rtc_timer_create(UINT_T time_period_sec, BOOL_T is_periodic,TKL_NB_SLP_TIMER_CB_T cb)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      创建睡眠定时器

    • Code: Select all

      /**
 * @brief Start a rtc timer
 *
 * @param null
 * @return OPERATE_RET OPRT_OK: success others: failed
 */
OPERATE_RET tkl_nbiot_psm_rtc_timer_start(VOID)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      启动睡眠定时器

    • Code: Select all

      /**
 * @brief Stop rtc timer
 *
 * @param null
 * @return OPERATE_RET OPRT_OK: success others: failed
 */
OPERATE_RET tkl_nbiot_psm_rtc_timer_stop(VOID)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

      停止睡眠定时器

    • Code: Select all

      /**
 * @brief Del rtc timer
 *
 * @param null
 * @return OPERATE_RET OPRT_OK: success others: failed
 */
OPERATE_RET tkl_nbiot_psm_rtc_timer_delete(VOID)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---

      删除睡眠定时器

  • 其他

    • Code: Select all

      /**
 * @brief Check the usb is active
 *
 * @return BOOL_T true: active false: not active
 */
BOOL_T tkl_nbiot_psm_usb_is_active(VOID)
{
    // --- BEGIN: user implements ---
    return false;
    // --- END: user implements ---
