//
// This module contains the implementation of entry and exit point
// of sample ADXL345 accelerometer driver.
//
//Environment:
//
// Windows User-Mode Driver Framework (UMDF)
#include "Device.h"
#include "Driver.h"
#include "Driver.tmh"
// This routine is the driver initialization entry point.

// DriverEntry must initialize members of DriverObject before it
// returns to the caller. DriverObject is allocated by the system
// before the driver is loaded, and it is released by the system
// after the system unloads the function driver from memory.

// driver can use the path to store driver related data between
// reboots. The path does not store hardware instance specific data.
