Cannot generate motion iterrupt MPU 6000

Hi All,

I'm new to the world of gyro, and I'm trying to enable the Motion Interrupt on the MPU 6000. As far as I know, it is different from the DMP.

I am able to communicate with the MPU 6000 through the SPI, and I can read the Data Ready Interrupt, and the Gyro and Accelerometer data.

When I'm checking for the value of the INT_STATUS register, I can only see the data ready interrupt.

I am enabling the Motion Interrupt by setting Bit 6 in register 0x38.
I set the Motion Threshold, MOT_THR to 0 in register 0x1F.
I am trying to read the interrupt from register 0x3A.

The datasheet mentions, that the axis and polarity of the motion can be read from register 97, but this register is not described in the datasheet.

Any kind of help would be welcome.

Thanks,
Istvan
