//Name: Project02Arduino
//By: Claudia Escue
//Purpose: send the values from an accelerometer to a processing file

#include <Wire.h> // Must include Wire library for I2C
#include <SFE_MMA8452Q.h> // Includes the SFE_MMA8452Q library

MMA8452Q accel; // Default MMA8452Q object create. (Address = 0x1D)

//create variables for the x, y, and z acceleration
float xAcceleration;
float yAcceleration;
float zAcceleration;

char val;

void setup() {
  
  Serial.begin(9600);
  accel.init(); //initialize the accelerometer

}

void loop() {
  //check if the accelerometer is available
  if (accel.available()) {
    accel.read(); // First, use accel.read() to read the new variables:
    printCalculatedAccels();
    Serial.println(); // Print new line every time.
  }
}

void printCalculatedAccels() {
 if(Serial.available() > 0){ 
    char input = Serial.read();
    val = Serial.read();

    //display accelerations as "x, y, z" so that it can be read in processing
    xAcceleration = accel.cx; 
    Serial.print(xAcceleration, 3);
    Serial.print(",");
    yAcceleration = accel.cy;
    Serial.print(yAcceleration, 3);
    Serial.print(",");
    zAcceleration = accel.cz;
    Serial.print(zAcceleration, 3);
    delay(250);
  }
