Good evening guys! Hope you are well
I'm doing a project that uses a BMP280. When I tested this code with an Arduino Uno, it worked well. But, when I tried using the ESP32 I have these problems:
/*

I tested a MPU6050 in this ESP32 and it worked well. But the code I tried for the BMP280 didn't have the same lucky.
The code is:
"
#include <Wire.h>
#include "i2c.h"
#include "i2c_Sensor.h";
#include "i2c_BMP280.h"
BMP280 bmp280;
void setup()
{
Serial.begin(9600);
Serial.print("Situacao do BMP280: ");
if (bmp280.initialize()) Serial.println("BMP280 DETECTADO"); //Detected
else
{
Serial.println("BMP280 não detectado"); //Not detected
while (1) {}
}
//Medida para setar os dados
bmp280.setEnabled(0);
bmp280.triggerMeasurement();
}
void loop()
{
//Espera medicao
bmp280.awaitMeasurement();
//Declara temperatura e pega ela
float temperature;
bmp280.getTemperature(temperature);
//Pega a pressao em pascal
float pascal;
bmp280.getPressure(pascal);
static float meters, metersold;
bmp280.getAltitude(meters);
metersold = (metersold * 10 + meters)/11;
bmp280.triggerMeasurement();
Serial.print(" Alt média: ");
Serial.print(metersold);
Serial.print(" m; Alt atual: ");
Serial.print(meters);
Serial.print(" Pressao: ");
Serial.print(pascal);
Serial.print(" Pa; T: ");
Serial.print(temperature);
Serial.println(" C");
delay(100);
}
''
Do you have any suggestions that I could do to solve it?
From now, thank you for your time!
Att, Bruno
