Detailed Description

An interface for the LIS302 triple axis I2C accelerometer. 

 // Print out the Z axis acceleration
 #include "mbed.h"
 #include "LIS302i2c.h"
 
 LIS302i2c acc(p28, p27); // sda, scl
 
 int main() {
     while(1) {
         printf("Z axis acceleration = %.2f\n", acc.getZ());
         wait(0.1);              
     }
 }
