Hi,
I am working on a prototype device that has the icm42670 and will use the Significant Motion Detector (SMD). But, I am unable to get the SMD to work. The device otherwise works as expected for temperature, gyroscope and accelerometer.
The registers are setup as follows...
INT_CONFIG (0x06) = 0x04 // This should setup INT1 as latched, open-drain, active low.
APEX_CONFIG1 (0x26) = 0x40 // This should enable the SMD
INT_SOURCE1 (0x2C) = 0x08 // This should route the SMD interrupt to INT1
