Return to Question

Im trying to understand the values that im getting from my MPU6050. I believe that there is a problem with my code. Im not entirely sure how the code is supposed to look like. There doesnt seem to be very many examples on the MPU6050.

After taking a look at the system print i found that the numbers that are written out is the time and not the values of the MPU6050. Why am i getting the zeros and nan for?

I got the code from a site and ive modified it because it didnt run for me. This is my Input:

I got the code from a site and I've modified it because it didn't run for me.

This is my code:

arx = (180/3.141592) * atan(ax / sqrt(pow(ay, 2) + pow(az, 2))); 
ary = (180/3.141592) * atan(ay / sqrt(pow(ax, 2) + pow(az, 2)));
arz = (180/3.141592) * atan(sqrt(square(ay) + square(ax)) / az);

Here is the Arudino errors that im getting from Martin's code. Im not sure why i cant make it into code form....

And this continues for a while obviously.

I also had a library problem thats fixed now.

// collect readings
accelgyro.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);

// apply gyro scale from datasheet
gsx = gx/gyroScale;   gsy = gy/gyroScale;   gsz = gz/gyroScale;

// calculate accelerometer angles
ary = -(180/3.141592) * atan(ax / sqrt(square(ay) + square(az))); 
arx =  (180/3.141592) * atan(ay / sqrt(square(ax) + square(az)));
arz = (180/3.141592) * atan(sqrt(square(ay) + square(ax)) / az);

// set initial values equal to accel values
if (i == 1) {
grx = arx;
gry = ary;
grz = arz;
}
// integrate to find the gyro angle
else{
grx = grx + (timeStep * gsx);
gry = gry + (timeStep * gsy);
grz = grz + (timeStep * gsz);
}  

// apply filter
rx = (0.1 * arx) + (0.9 * grx);
ry = (0.1 * ary) + (0.9 * gry);
rz = (0.1 * arz) + (0.9 * grz);

 Serial.print(ax);   Serial.print("\t");
 Serial.print(ay);   Serial.print("\t");
 Serial.print(az);   Serial.print("\t\t");
 Serial.print(gx);   Serial.print("\t");
 Serial.print(gy);   Serial.print("\t");
 Serial.print(gz);   Serial.print("\t\t");
 Serial.print(arx);   Serial.print("\t");
 Serial.print(ary);   Serial.print("\t");
 Serial.print(arz);   Serial.print("\t\t");
