You probably don't need to calibrate the accelerometer. The modern ones are reasonably accurate "out of the box". To test the calibration, hold the sensor still with any axis vertical, and the reading along that axis will correspond +1 g or -1 g, depending on whether it is pointing up or down.

Calibrating the gyro is very simple. On startup, collect a few hundred X, Y and Z gyro readings while the sensor motionless, add them up and calculate the averages, which are good estimates of the zero offsets. Subtract the zero offsets from subsequent readings.

Thank you very much Indeed!
