 ### Configuration

+1. Make the following configuration changes in your `/home/pi/mycar/myconfig.py`:
 
 ``` python
 #IMU
 HAVE_IMU = True
 IMU_SENSOR = 'mpu9250'          # (mpu6050|mpu9250)
-IMU_DLP_CONFIG = 3
+IMU_DLP_CONFIG = 0x05           # Digital Lowpass Filter setting (0x00:250Hz, 0x01:184Hz, 0x02:92Hz, 0x03:41Hz, 0x04:20Hz, 0x05:10Hz, 0x06:5Hz)
+IMU_ADDRESS = 0x69              # Please use i2c_detect to validate this address (0x68, 0x69, other; depends on your configuration)
 ```
 `IMU_SENSOR` can be either `mpu6050` or `mpu9250` based on the sensor you are using.
 
 `IMU_DLP_CONFIG` allows to change the digital lowpass filter settings for your IMU. Lower frequency settings (see below) can filter high frequency noise at the expense of increased latency in IMU sensor data.

 ### Notes on MPU9250
-At startup the MPU9250 driver performs calibration to zero accel and gyro bias. Usually the process takes less than 10 seconds, and in that time avoid moving or touching the car.
-Please place the car on the ground before starting Donkey.
+If you are using Robohat MM1, the MPU9250 come presoldered and the following is applicable to you.
+The self-calibration routine currently does not function.
+This is why we comment out the corresponding line `54` in the second configuration step above.
+Factory calibration is thus considered as minimum sufficient.
+
+In case the calibration routine gets fixed in the future, the following applies:
+At startup the MPU9250 driver performs calibration to zero accel and gyro bias. 
+Usually this process takes less than 10 seconds.
+Avoid moving or touching the car during this time.
+It is best to place the car on flat ground when first launching a driving script that relies on the imu.
