Stuck on calibration for (LSM303) Accelerometer

Using Arduino Sensors

This is not correct. lms.accelData.x (or y or z) is only updated after calls to lsm.read(). If you .read() it once then look at it 100 times it will be the same value.

gdavisiv:

  for (int i=0; i<100; i++)

{
   XSum += ((int)lsm.accelData.x);
   //YSum += analogRead(YPin);
   //ZSum += analogRead(ZPin);
 }
 
 lsm.read();

Not sure why you're getting a crazy value here though:

Serial.print(map(XSum/100, XMin, XMax, -2000, 2000));
