I am not able to use the FXOS8700CQ accelerometer present on the kv31f board.
I would like to use the freefall function and for this I configured the following registers.
|Freefall Configuration||Z < 0,3g using MFF Function 4g, 100 Hz ODR, Normal Mode|
|Register Name||Register Addr||Data (R/W)||Description|
|CTRL_REG1||0x2A||0x00 W||Standby mode for writable operations|
|WHO_AM_I||0x0D||Read||Check device communication (0xC7)|
|XYZ_DATA_CFG||0x0E||0x01 W||Hight-pass filter disabled, +/-0.488mg/LSB|
|CTRL_REG1||0x2A||0x18 W||Set the device in 100 Hz ODR, Standby|
|A_FFMT_CFG||0x15||0xA0 W||Latch enable, Freefall, Z axis|
|A_FFMT_THS||0x17||0x05 W||0,3g threshold|
|A_FFMT_COUNT||0x18||0x0A W||Debounce 100ms|
|CTRL_REG4||0x2D||0x04 W||FF interrupt enable|
|CTRL_REG5||0x2E||0x04 W||interrupt routed to INT1 pin|
|CTRL_REG1||0x2A||0x19 W||Set the device in 100 Hz ODR, Active Mode|
- The communication is working properly because I can read the WHO_AM_I register,
- I've already followed the AN4070 document,
But it's not working, the Freefall interrupt isn't happening,
I've tried to use the 3 axes and then only one but none worked.
Is there any other register that I need to configure?
What else should I do?
