Hello all, I have a mpu 9150 IMU sensor, Arduino DUE and I am using mpu6050.h to get IMU data. I have used MPU6050::setRate function to set different sampling rate (0~244) and it was verified by using MPU6050::getRate function. However, when I use below codes to check sampling rate of getMotion9 function, the rate always keep around 40Hz: mytime_pre=micros(); MPU6050.getMotion9(&ax, &ay, &az, &gx, &gy, &gz, &mx, &my, &mz); mytime=micros(); sample_rate=mytime-mytime_pre As far as I know, the sampling rate can be far more than 40Hz (I have disabled the low pass filter by using setDLPFMode(0). Did I do anything wrong while setting up sampling rate? Thanks you in advanced.
