mfiore 0:a44e71488e1f 2 * Dragonfly Example program for 2015 AT&T Government Solutions Hackathon
mfiore 0:a44e71488e1f 3 *
mfiore 0:a44e71488e1f 4 * The following hardware is required to successfully run this program:
mfiore 0:a44e71488e1f 5 * - MultiTech UDK2 (4" square white PCB with Arduino headers, antenna
mfiore 0:a44e71488e1f 6 * connector, micro USB ports, and 40-pin connector for Dragonfly)
mfiore 0:a44e71488e1f 7 * - MultiTech Dragonfly (1"x2" green PCB with Telit radio)
mfiore 0:a44e71488e1f 8 * - Seeed Studio Base Shield
mfiore 0:a44e71488e1f 9 * - Grove moisture sensor (to connect to Base Shield)
mfiore 0:a44e71488e1f 10 * - Grove button (to connect to Base Shield)
mfiore 0:a44e71488e1f 11 * - MEMs Inertial and Environmental Nucleo Expansion board (LSM6DS0
mfiore 0:a44e71488e1f 12 * 3-axis accelerometer + 3-axis gyroscope, LIS3MDL 3-axis
mfiore 0:a44e71488e1f 13 * magnetometer, HTS221 humidity and temperature sensor and LPS25HB
mfiore 0:a44e71488e1f 14 * pressure sensor)
mfiore 0:a44e71488e1f 15 *
mfiore 0:a44e71488e1f 16 * What this program does:
mfiore 0:a44e71488e1f 17 * - reads data from all sensors on MEMs board and moisture sensor on a
mfiore 0:a44e71488e1f 18 * periodic basis
mfiore 0:a44e71488e1f 19 * - prints all sensor data to debug port on a periodic basis
mfiore 0:a44e71488e1f 20 * - optionally send a SMS containing sensor data when the Grove Button
mfiore 0:a44e71488e1f 21 * is pushed (phone number must be configured)
mfiore 4:730b61258422 22 * - optionally sends sensor data to AT&T M2X cloud platform (user must
mfiore 4:730b61258422 23 * create own M2X account and configure a device)
mfiore 0:a44e71488e1f 24 *
mfiore 0:a44e71488e1f 25 * Setup:
mfiore 0:a44e71488e1f 26 * - Correctly insert SIM card into Dragonfly
mfiore 0:a44e71488e1f 27 * - Seat the Dragonfly on the UDK2 board
mfiore 0:a44e71488e1f 28 * - Connect an antenna to the connector on the Dragonfly labled "M"
mfiore 0:a44e71488e1f 29 * - Stack the Base Shield on the UDK2 Arduino headers
mfiore 0:a44e71488e1f 30 * - Connect the Grove button to the D8 socket on the Base Shield
mfiore 0:a44e71488e1f 31 * - Connect the Grove moisture sensor to the A0 socket on the Base
mfiore 0:a44e71488e1f 32 * Shield
mfiore 3:f6bceb9e5e1a 33 * - Make sure the reference voltage selector switch (next to the A0
mfiore 3:f6bceb9e5e1a 34 * socket) is switched to 5V so you get accurate analog readings
mfiore 0:a44e71488e1f 35 * - Stack the MEMs board on top of the Base Shield
mfiore 0:a44e71488e1f 36 * - Plug in the power cable
mfiore 0:a44e71488e1f 37 * - Plug a micro USB cable into the port below and slightly to the
mfiore 0:a44e71488e1f 38 * left of the Dragonfly (NOT the port on the Dragonfly)
mfiore 0:a44e71488e1f 39 *
mfiore 0:a44e71488e1f 40 * Go have fun and make something cool!
mfiore 0:a44e71488e1f 41 *
