Hope to get some basic (I think) help

I’m using the SparkFun ADXL345 on a Arduino UNO board.

I’m attempting to run a 1 axis self leveling platform.

When I run the Arduino software to compile, I get a error message,

“'SparkFun_ADXL345_Unified’ does not name type”

I believe I have all the correct library’s installed, but not 100% positive.

I’m VERY new to this.

Any and all comments or recommendations would greatly be appreciated.

Thank You

FYI. The line of error is:

SparkFun_ADXL345_Unified accel = SparkFun_ADXL345_Unified(12345)

would help if you have a link to the software or share the code of the sketch. looks to me you try to create a constructor. It should be something like: ADXL345 accel = ADXL345(10).

So leave out SparkFun_ . Also the 12345 is the chip select pin for SPI communication and I am sure this is not a right number. Look at the examples that have been provided with the library to start

Will attempt to understand you welcome comment. But again I know nothing about this coding.

Enclosed is the entire code to see if this helps.

Thank You

#include <Servo.h>

#include <SparkFun_ADXL345.h>

// Create servo objects for x and y servos

Servo xServo;

// Used to level the platform, if needed

int xOffset = -7;

// int sensitivity = 50; ORIGIONAL CODE, Changed to below. Works better.

int sensitivity = 0;

// Assign a unique ID to this sensor at the same time

SparkFun_ADXL345_Unified accel = SparkFun_ADXL345_Unified(12345); // THIS IS THE ERROR LINE

void setup() {

Serial.begin(9600);

// Initialize sensor

if(!accel.begin())

{

// Sensor not detected

Serial.println(“No Sensor detected”);

while(1);

}

// Connect servos to pins

xServo.attach(9);

// Setup sensor Range and datarate

accel.setRange(ADXL345_RANGE_16_G);

accel.setDataRate(ADXL345_DATARATE_25_HZ);

}

void loop() {

sensors_event_t event;

accel.getEvent(&event);

// Get x and y values from sensor

int x = event.acceleration.x;

// map sensor value (-10 - 10) to servo position value (30 - 150)

int x1 = map(x, -10, 10, 130, 50);

// Troubleshoot info - show sensor reading and mapping

Serial.print("X: "); Serial.print(x);

Serial.print("\tX1: "); Serial.print(x1);

// move servos based on sensor mapping

xServo.write(x1 + xOffset);

delay(sensitivity); //delay to decrease sensitivity

}

Take a look at the examples that are provided with the library. That is the best way to start if you do not know enough (yet). I really appreciate your effort to get going and that your have to start somewhere, as we all did. Start with something that works and take it from there.
