加速度计采用i2c控制

嗨,对话框的团队,

我尝试操作，添加加速度计控制代码到“ble_app_sleepmode”。
我可以初始化并读取Accelerometer值。

并且，我添加了Accelerometer控制代码来中断“ble_app_sleepmode”的处理，如下所示。
我是用逻辑分析仪测量的。
当我按下按键时，DA14580没有发送I2C信号。

//读取按钮状态

｛
app_sleep_env。custs1_btn_state = CUSTS1_BTN_STATE_RELEASED;
next_btn_event = WKUPCT_PIN_POLARITY_LOW;

其他的

next_btn_event = WKUPCT_PIN_POLARITY_HIGH;
｝

//设置next button事件
user_app_set_button_event (next_btn_event);
｝

然而，当我按下按钮时，它就停止了。
你能告诉我为什么它停止了? ?
