how i calibrate acceleration of accelerometer lsm303dlm-ARDUINO UNO....SOS!!!!!!

Using Arduino Sensors

I use this code to calibrate the LSM303 compass:

#include <Wire.h>
#include <LSM303.h>

LSM303 compass;
LSM303::vector running_min = {2047, 2047, 2047}, running_max = {-2048, -2048, -2048};

void setup() {
Serial.begin(9600);
Wire.begin();
compass.init();
compass.enableDefault();
}

void loop() {
compass.read();

running_min.x = min(running_min.x, compass.m.x);
running_min.y = min(running_min.y, compass.m.y);
running_min.z = min(running_min.z, compass.m.z);

running_max.x = max(running_max.x, compass.m.x);
running_max.y = max(running_max.y, compass.m.y);
running_max.z = max(running_max.z, compass.m.z);

Serial.print("M min ");
Serial.print("X: ");
Serial.print((int)running_min.x);
Serial.print(" Y: ");
Serial.print((int)running_min.y);
Serial.print(" Z: ");
Serial.print((int)running_min.z);

Serial.print(" M max ");
Serial.print("X: ");
Serial.print((int)running_max.x);
Serial.print(" Y: ");
Serial.print((int)running_max.y);
Serial.print(" Z: ");
Serial.println((int)running_max.z);

delay(100);
}

and i take maximum and minimum values for X,Y,Z ....how to use after these values???how i can use this code or this value to calibrate the acceleration value????i want code for calibrate acceleration value please....and then what can i do....???/

Gravity is a cheap and plentiful source of calibration data for accelerometers.

Please use code tags when posting code.

I want a code to calculate the acceleration and then speed please!!!!!

I don't have one, sorry.
