==Accelerometer Calibration==
==Accelerometer Calibration==
Calibration algorithm is used to recalculate accelerometer axes to represent vehicle‘s axes (see Picture 1). Vehicles axes are as follows:<br>
1. X is front.<br>
2. Y is left.<br>
3. Z is down.<br>

Once vehicle‘s axes are calculated, device is considered calibrated.<br>
<br>
Note: moving forward along any axis will generate negative values. This means acceleration will generate -X values, accordingly breaking will generate X values. Same goes for other axes. <br>
Commands that can be used during calibration:<br>
