For this problem, we will calculate the magnitude of the acceleration from the DualShock 4. You will read from ds4rd.exe, but this time you will read the inputs over and over inside the while loop. Your code should be written in a modular fashion and include 3 or more of your own functions.

When the DualShock 4 is not moving, your program should output a line saying which side of the DualShock 4 is facing up. Consider using the magnitude of the acceleration (-a) for movement detection. You will need a tolerance value for this---experiment to find one that seems reasonable. You will need to use the gyroscope values (-g) to determine the orientation. Again, you may want a separate tolerance value. (see development tips below about the close_to function and tolerance values)

For instance, when laying flat and still on the table with buttons up, it should output TOP. Flipping the DualShock 4 over, when still, it should output BOTTOM. When setting the left side of the DualShock 4 (i.e. side with the d-pad buttons) down and the right side up, your program should output RIGHT and when flipped (ie side with the shape buttons down), LEFT. When the LED light bar is pointed up, output FRONT and similarly when the LED light bar is down it should read BACK.

Requirements

Basics

• Program outputs orientation of Dualshock when not moving

• Program includes and uses 3 or more of your own functions

/* It would be wise (mainly save time) if you copy your code to calculate the magnitude from last week (lab 3). You will also need to copy your prototypes and functions to the appropriate sections in this program. */

//printf("At %d ms, the acceleration's magnitude was: %f ", t, mag(ax, ay, az));

return 0; }
