KC868-A4S ESP32 I/O pin define
#2
Hi, I am tried to use i2c (iic), with a bme 280 sensor, but it does not works, please caun you help to fix the problem or can you provide me a explication how to use the sensor. I used the netx programation:
#include <Wire.h>
#include <SPI.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>

#define BME_SCK 13
#define BME_MISO 12
#define BME_MOSI 11
#define BME_CS 10

#define SEALEVELPRESSURE_HPA (1013.25)

Adafruit_BME280 bme; // I2C


unsigned long delayTime;

void setup() {
Serial.begin(9600);
while(!Serial); // time to get serial running
Serial.println(F("BME280 test"));

unsigned status;

// default settings
status = bme.begin();
// You can also pass in a Wire library object like &Wire2
status = bme.begin(0x76);
if (!status) {
Serial.println("Could not find a valid BME280 sensor, check wiring, address, sensor ID!");
Serial.print("SensorID was: 0x"); Serial.println(bme.sensorID(),16);
Serial.print(" ID of 0xFF probably means a bad address, a BMP 180 or BMP 085\n");
Serial.print(" ID of 0x56-0x58 represents a BMP 280,\n");
Serial.print(" ID of 0x60 represents a BME 280.\n");
Serial.print(" ID of 0x61 represents a BME 680.\n");
while (1) delay(10);
}

Serial.println("-- Default Test --");
delayTime = 1000;

Serial.println();
}


void loop() {
printValues();
delay(delayTime);
}


void printValues() {
Serial.print("Temperature = ");
Serial.print(bme.readTemperature());
Serial.println(" °C");

Serial.print("Pressure = ");

Serial.print(bme.readPressure() / 100.0F);
Serial.println(" hPa");

Serial.print("Approx. Altitude = ");
Serial.print(bme.readAltitude(SEALEVELPRESSURE_HPA));
Serial.println(" m");

Serial.print("Humidity = ");
Serial.print(bme.readHumidity());
Serial.println(" %");

Serial.println();
}
