Posted on April 24, 2018 at 17:11I am trying to configure an interrupt on a LIS2DH12 in order to detect when the device is being hit.
I tried just configuring one axes to generate the interrupt. But Interrupt is never being fired (Or it is fired constantly). This is my current configuration:
20---- 67
21---- 0
22---- 40
23---- 0
24---- 8
25---- 0
26---- 0
27---- ff
28---- 40
29---- 0
2a---- c0
2b---- ff
2c---- 80
2d---- 44
2e---- 0
2f---- 20
30---- 10
31---- 55
32---- 40
33---- 0
34---- 0
35---- 0
36---- 0
37---- 0
38---- 0
39---- 0
3a---- 0
3b---- 0
3c---- 0
3d---- 0
3e---- 0
Leaving the device over the table where I work, gives a constant measurement of:
x: 0 y: 0 z: 63
And int1Source register gives 0x25 which seems to be 0010 0101. I have just configured ZLow to trigger the interrupt but I get that XL, YL and ZH but not IA so interrupt is not generated by register. INT1 pin is always on in this case.
What should I do in order to configure a movement in any of the 3 axis? I want that my device stays in a position and detect any movement in any of the axes configured over the threshold set(For example, any movement higher than 1G). But I think I cannot detect at the same time ZH or ZL, XL or XH or YL or YH. I mean, if the device reads 64, trigger an interrupt over 0 or 128 in that axes. Is this possible?
