/*************************************************************************
 * Dragonfly Example program for 2016 Sprint Exosite Training
 *
 * The following hardware is required to successfully run this program:
 *   - MultiTech UDK2 (4" square white PCB with Arduino headers, antenna
 *     connector, micro USB ports, and 40-pin connector for Dragonfly)
 *   - MultiTech Dragonfly (1"x2" green PCB with Telit radio)
 *   - Rohm Electronics Sensor Board

 *   - Expansion board (LSM6DS0
 *     3-axis accelerometer + 3-axis gyroscope, LIS3MDL 3-axis
 *     magnetometer, HTS221 humidity and temperature sensor and LPS25HB
 *     pressure sensor)
 *
 * What this program does:
 *   - reads data from all sensors on board
 *   - prints all sensor data to debug port on a periodic basis
 *   - optionally send data to Exosite
 *   - All data is sent to a specific location determined by the student login.
 *   - Exosite cloud platform (user must create own account and configure a device
 *       - you need to set the "VENDOR" and "MODEL"

 *       - you need to set the "do_cloud_post" flag to true for this to
 *         work
 *
 * Setup:
 *   - Correctly insert SIM card into Dragonfly
 *   - Seat the Dragonfly on the UDK2 board
 *   - Connect an antenna to the connector on the Dragonfly labled "M"
 *   - Stack the Base Shield on the UDK2 Arduino headers
 *   - Stack the MEMs board on top of the Base Shield
 *   - Plug in the power cable
 *   - Plug a micro USB cable into the port below and slightly to the
 *     left of the Dragonfly (NOT the port on the Dragonfly)
 *
 * Go have fun and make something cool!

/*
Sample Program Description:
   This Program will enable to Multi-Tech Dragonfly platform to utilize ROHM's Multi-sensor Shield Board.
   This program will initialize all sensors on the shield and then read back the sensor data.
   Data will then be output to the UART Debug Terminal every 1 second.

Sample Program Author:
   ROHM USDC

Additional Resources:
   ROHM Sensor Shield GitHub Repository: https://github.com/ROHMUSDC/ROHM_SensorPlatform_Multi-Sensor-Shield
