LPS28DFW micro

Hello,

Actually i’m trying to mesure the pressure using LPS28DFW and arduino uno, but i have some problems, the i2c communication does not working.

the sensor work with arduino uno or there something to do ?

Can help me please and thank you ?

arduino code :

#include <Wire.h>

#include “SparkFun_LPS28DFW_Arduino_Library.h”

// Create a new sensor object

LPS28DFW pressureSensor;

// I2C address selection

uint8_t i2cAddress = LPS28DFW_I2C_ADDRESS_DEFAULT; // 0x5C

//uint8_t i2cAddress = LPS28DFW_I2C_ADDRESS_SECONDARY; // 0x5D

void setup()

{

// Start serial

Serial.begin(115200);

Serial.println(“LPS28DFW Example 1 - Basic Readings!”);

// Initialize the I2C library

Wire.begin();

// Check if sensor is connected and initialize

// Address is optional (defaults to 0x5C)

while(pressureSensor.begin(i2cAddress) != LPS28DFW_OK)

{

// Not connected, inform user

Serial.println(“Error: LPS28DFW not connected, check wiring and I2C address!”);

// Wait a bit to see if connection is established

delay(1000);

}

Serial.println(“LPS28DFW connected!”);

}

void loop()

{

// Get measurements from the sensor. This must be called before accessing

// the pressure data, otherwise it will never update

pressureSensor.getSensorData();

// Print temperature and pressure

Serial.print("Temperature (C): ");

Serial.print(pressureSensor.data.heat.deg_c);

Serial.print(“\t\t”);

Serial.print("Pressure (hPa): ");

Serial.println(pressureSensor.data.pressure.hpa);

// Only print every second

delay(1000);

}

Are you using A4 & A5? How long are the wires? If they are larger/longer you may need to disable the i2c pullup on the sensor https://learn.sparkfun.com/tutorials/sp … e-overview
