Hello, I want to configure LIS2DH for generating interrupt for single click as well as double click, Can we do that? I am using INT1 for FIFO so INT2 is for clicks interrupt, Individually I can able to get interrupt from them but when I am combining single and double click in same code, I am not able to get single interrupt, Its showing only for double INT.

My sensors configurations are as below. Please suggest.

CTRL_REG1 =

0x37

CTRL_REG2 = 0x00CTRL_REG3 = 0x04CTRL_REG4 = 0x10CTRL_REG5 = 0x40CTRL_REG6 = 0x80

FIFO_CTRL_REG=0x99

CLICK_CFG = 0x3F

CLICK_THS = 0x20TIME_LIMIT = 0x10TIME_LATENCY = 0x10TIME_WINDOW = 0x40

Thanks

It is not possible to detect single click as well as double click. You can use either single click or double click.

Thank, I want to know one thing, Can we relay on single tap interrupt from accelerate, I performed some test. Out of 15 times, we was missing single tap detection twice. I want to use it like a touch screen. As per my setup, I need to put lis2dh inside some box and when ever some one single tap outer surface,  it should generate detection. Can we performed same ?

One more thing, Will other movements on the box like some movement will cause single tap suppose some hold it on hand and walk?
