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.
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);
}
