Hello together,
has someone figured out how to enable the motion wakeup of the ICM-20649 with the driver provided by Invensense? I already got the IMU working on my embedded system to return correct accelerometer and gyro values while measurement is running, so it should be initialized correctly. Unfortunately I wasn't able to set up the motion wakeup correctly to get an interrupt on PIN1 of the ICM-20649 till now.
I already tried to make the motion wakeup working with the following functions (in different combinations) without luck:
dmp_set_wom_motion_threshold_20649(...)
dmp_set_wom_time_threshold_20649(...)
dmp_set_wom_enable_20649(...)
inv_icm20649_set_sensor_period(...)
inv_icm20649_set_wom_threshold(...)
inv_icm20649_enable_sensor(...)
Perhaps if someone here knows the correct initialization, that would be very helpfull, because the example code provided by Invensense doesn't provide the init routine for the motion wakeup.
Best regards,
Stefan
