[objective] to reduce power consumption, don't want to often wake MCU, my way is to open the DMP, sensor sampling frequency and FIFO output frequency is set to 20 hz, so the interruption of 20 hz reads a FIFO packets (ACC_XYZ GRYO_XYZ, quaternion); Now, want to FIFO output frequency is set to 1 hz, interrupt comes loop read 20 times FIFO data packets, but read data is 0; Don't know whether I MPU6050 does not support this function, passing the great spirit show 1, 2, thank you
