Detailed Description

Accelerometer MMA7660FC class.

Example: 

 #include "mbed.h"
 #include "MMA7660FC.h"
 
 #define ADDR_MMA7660 0x98
 
 MMA7660FC Acc(p28, p27, ADDR_MMA7660);

          Acc.read_Tilt(&x, &y, &z);
          pc.printf("Tilt x: %2.2f degree \n", x);                    // Print the tilt orientation of the X axis
          pc.printf("Tilt y: %2.2f degree \n", y);                    // Print the tilt orientation of the Y axis
