Interrupt when device start outs at an angle?

[ashishgururani]

The following code works great if the device starts out flat. But if the device boots at an angle, it constantly prints "Interrupt pin is HIGH. OK". Any way to fix that so when the device is booted at an angle, the interrupt does not fire, but fires when the device is further moved?

#include <Wire.h>
#include "SparkFun_LIS2DH12.h"

SPARKFUN_LIS2DH12 accel;

int accelInterruptPin = 5;

void setup()
{
  Serial.begin(115200);
  delay(500);
  Serial.println("SparkFun Accel Example");

  Wire.begin();

  if (!accel.begin(24))
  {
    Serial.println("Accelerometer not detected. Check address jumper and wiring. Freezing...");
    while (1);
  }

  pinMode(accelInterruptPin, INPUT_PULLDOWN);

  accel.setDataRate(LIS2DH12_POWER_DOWN); //Stop measurements

  // Set INT_POLARITY to Active Low
  accel.setIntPolarity(HIGH);

  // Set INT1 interrupt
  accel.setInt1IA1(true);

  // Set INT1 threshold and duration for any movement detection
  accel.setInt1Threshold(6); // Set threshold to the smallest value for any movement
  accel.setInt1Duration(9);  // Set a duration to filter out noise

  // Clear the interrupt
  while (accel.getInt1()) delay(10); // Reading int will clear it

  // Set data rate and enable interrupts
  accel.setDataRate(LIS2DH12_ODR_400Hz); 
  accel.setInt1(true); // Enable interrupts on INT1 pin

  Serial.println("Begin Interrupt Scanning");
  Serial.println("Detecting any movement...");
}

void loop()
{
  // Check the interrupt pin
  if (digitalRead(accelInterruptPin) == HIGH) {
    if (accel.getInt1() == true) {  // Reading int will clear it
      Serial.println("Interrupt pin is HIGH. OK");
    }
    else {
      Serial.println("Interrupt pin is HIGH. This shouldn't print");
    }
  } else {
    Serial.println("Interrupt pin is LOW");
  }
  delay(200);
}
