esp8266-12e node mcu is not detecting adxl345

Postby rajatjain313 » Fri Sep 13, 2019 11:27 am

hello everyone ,
i have done conection of adxl345 and esp8266-12enode mcu for vibration . the connection is in i2c .but my esp8266-12e node mcu is not detecting adxl345

here is my code


#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_ADXL345_U.h>

#define scl D1
#define sda D2

/* Assign a unique ID to this sensor at the same time */
Adafruit_ADXL345_Unified accel = Adafruit_ADXL345_Unified(12345);

void displaySensorDetails(void)
{
sensor_t sensor;
accel.getSensor(&sensor);
Serial.println("------------------------------------");
Serial.print ("Sensor: "); Serial.println(sensor.name);
Serial.print ("Driver Ver: "); Serial.println(sensor.version);
Serial.print ("Unique ID: "); Serial.println(sensor.sensor_id);
Serial.print ("Max Value: "); Serial.print(sensor.max_value); Serial.println(" m/s^2");
Serial.print ("Min Value: "); Serial.print(sensor.min_value); Serial.println(" m/s^2");
Serial.print ("Resolution: "); Serial.print(sensor.resolution); Serial.println(" m/s^2");
Serial.println("------------------------------------");
Serial.println("");
delay(500);
}

void displayDataRate(void)
{
Serial.print ("Data Rate: ");

switch(accel.getDataRate())
{
case ADXL345_DATARATE_3200_HZ:
Serial.print ("3200 ");
break;
case ADXL345_DATARATE_1600_HZ:
Serial.print ("1600 ");

case ADXL345_DATARATE_0_10_HZ:
Serial.print ("0.10 ");
break;
default:
Serial.print ("???? ");
break;
}
Serial.println(" Hz");
}

void displayRange(void)
{
Serial.print ("Range: +/- ");

switch(accel.getRange())
{
case ADXL345_RANGE_16_G:
Serial.print ("16 ");
break;
case ADXL345_RANGE_8_G:
Serial.print ("8 ");

break;
case ADXL345_RANGE_2_G:
Serial.print ("2 ");
break;
default:
Serial.print ("?? ");
break;
}
Serial.println(" g");
}

void setup(void)
{
pinMode(scl,INPUT_PULLUP);
pinMode(sda,INPUT_PULLUP);
Serial.begin(9600);
Wire.begin(scl,sda);
Serial.println("Accelerometer Test"); Serial.println("");
accel.begin();

/* Initialise the sensor */
if(!accel.begin())
{
/* There was a problem detecting the ADXL345 ... check your connections */
Serial.println("Ooops, no ADXL345 detected ... Check your wiring!");
while(1);
}

/* Set the range to whatever is appropriate for your project */
accel.setRange(ADXL345_RANGE_16_G);
// displaySetRange(ADXL345_RANGE_8_G);

/* Display some basic information on this sensor */
displaySensorDetails();

/* Display additional settings (outside the scope of sensor_t) */
displayDataRate();
displayRange();
Serial.println("");
}

void loop(void)
{
/* Get a new sensor event */
sensors_event_t event;
accel.getEvent(&event);

/* Display the results (acceleration is measured in m/s^2) */
Serial.print("X: "); Serial.print(event.acceleration.x); Serial.print(" ");

Serial.print("Z: "); Serial.print(event.acceleration.z); Serial.print(" ");Serial.println("m/s^2 ");

}


so please help

This is a forum for the ESP8266 ESP32, not the ESP32 ESP8266 (thanks rudi). Suggest you ask your question on e.g. https://bbs.espressif.com/ or on a nodemcu-related forum instead.

:D

I think ESP_Sprite has the other way meant:
This is a forum for the ESP32, not the ESP8266.

also you can ask in 8266 forum also look to the adxl345 help and the wiring -example-code-side

also check your used pins - with your board,
better, like ESP-Sprite wrote, you talk this theme in 8266 forum, cause here is esp32 forum and 8266 solution's better archived in the 8266 forum and folks.
