In this example we connect a LIS3DSH sensor to a Linkit One. Lets look at the sensor first of all

The LIS3DSH is an ultra-low-power high-performance three-axis linear accelerometer belonging to the “nano” family with an embedded state machine that can be programmed to implement autonomous applications.

The LIS3DSH has dynamically selectable full scales of ±2g/±4g/±6g/±8g/±16g and is capable of measuring accelerations with output data rates from 3.125 Hz to 1.6 kHz. The self-test capability allows the user to check the functioning of the sensor in the final application. The device can be configured to generate interrupt signals activated by user-defined motion patterns.

The LIS3DSH has an integrated first-in, first-out (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor. The LIS3DSH is available in a small thin plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

Code

You need to download and install the https://github.com/yazug/LIS3DSH library

#include <Wire.h>
#include <LIS3DSH.h>
 
LIS3DSH accel;
 
void setup() 
{
  Serial.begin(9600);
  Wire.begin();
  accel.enableDefault();
}
 
void loop() 
{
  int16_t x, y, z;
  int8_t temperature;
 
  accel.readAccel(&x, &y, &z);
  accel.readTemperature(&temperature);
 
  Serial.print("Accel ");
  Serial.print("X: ");
  Serial.print(x);
  Serial.print(" Y: ");
  Serial.print(y);
  Serial.print(" Z: ");
  Serial.print(z);
  Serial.print(" T: ");
  Serial.println(temperature);
 
  delay(100);
}

 

Output

Open the serial monitor and you should see something like this – move the module around
