Detailed Description

Class to read acceleration measurements from Dimension Engineering Buffered +-3g Tri-axis Accelerometer device.

Example 

 #include "mbed.h"
 #include "DimEngAcc3D.h "

 int main() {
     DimEngAcc3D *acc;

     // Create and configure object for 3.3V powered device,
     acc = new DimEngAcc3D(p18, p19, p20);
     acc->setVoltage(3.3);

     while(1) {
         // Read.
         acc->read();

         // Print and delay 0.5s.
         printf("%.3f, %.3f, %.3f\r\n", acc->x, acc->y, acc->z);
         wait(0.5);
     }
 }

~DimEngAcc3D ( void   )

Destructor.

Definition at line 51 of file DimEngAcc3D.cpp.

Member Function Documentation

void read ( void   )

Read acceleration and store in x, y & z.

Definition at line 88 of file DimEngAcc3D.cpp.

void setVoltage ( float  voltage )

Specify the supply voltage used by the device.

Parameters:
voltageThe specified voltage (default 3.3)
