g-sensor通过i2c连接到DA14585。有一个中断引脚。
传感器的中断设计为初始高，一旦数据准备好，中断引脚先低后高。
I would like to detect the rising edge for the interrupt pin, and I configure it如下: in void set_pad_functions(void):
GPIO_ConfigurePin(I2C_INT1_PORT, I2C_INT1_PIN, INPUT_PULLUP, PID_GPIO, true);//G Sensor INT1
GPIO_RegisterCallback(GPIO0_IRQn, LIS3DH_Interrupt1_Handler);
GPIO_EnableIRQ(I2C_INT1_PORT, I2C_INT1_PIN, GPIO0_IRQn, false, true, 3);/ / 0 =比;然而，我发现我的回调函数将在每次唤醒时间被调用。
The reason may be that the GPIO_EnableIRQ(in set_pad_functions) is set again and the interrupt pin is high at that time.
As I know, the GPIO interruption of DA14585 is level triggered, right?
Do you guys have any idea to solve this problem?
Thanks.
