Kit Overview

The Xtrinsic sensor evaluation kit comes with a sensor board together with the Freescale FRDM-KL25Z platform.

The software drivers and code enable engineers to easily evaluate and demonstrate the performance of the

sensors in a variety of applications including:

• eCompass

• Mobile Phones/Tablet Computers

• Remote Control/Wireless Mouse

• Game Consoles

• Navigation Devices

• Medical Devices

Kit Contents:

• Xtrinsic Sensors Board

• FRDM-KL25Z board

• Quick Start Guide

Xtrinsic Sensor Board

The sensor board comes equipped with three of Freescale's new-generation XTRINSIC MEMS sensors. The

MPL3115 is designed for accurate measurement of altitude and pressure, the MAG3110 for detection of magnetic

fields, and the MMA8491 for measurement of physical positions.

Figure 1 Sensor Board

MPL3115

The MPL3115 is a high-precision sensor used to provide accurate pressure and altitude data. It features an

adjustable sampling rate, ultra-low power consumption and intelligent functions, suitable for applications such as

mobile, medical and security devices. MPL3115 is able to provide digitized output, two separated wake-up

interrupts, minimum/maximum threshold mechanism, and autonomous data acquisition. The self data processing

ability of the MPL3115 reduces the need for communication with MCUs, which reduces overall system power

consumption.

MAG3110

The MAG3110 is a small, low-power, digital 3-axis magnetometer featuring a wide measurement range. It can

measure magnetic fields (the overlapped fields consisting of the geomagnetic field and the fields created by

components on PCB) on each of the 3 axes in the position where it is placed. The MAG3110 features an I2C serial

interface, and is capable of measuring magnetic fields of up to 10 Gauss with an output data rate up to 80Hz. The

output data rate can vary depending on the sampling intervals and may be adjusted from 12ms to several

seconds.

MMA8491Q

The MMA8491Q is a low voltage, 3-axis low-g accelerometer housed in a 3 mm by 3 mm QFN package. The device

can accommodate two accelerometer configurations, acting as either an easy to implement 45° Tilt Sensor or a

digital (I2C) output accelerometer. In the 45° Tilt Sensor mode, it offers extremely easy board implementation by

using a single line of output per axis. In the digital output mode, 14-bit ±8g raw data can be read from the device

with high 1 mg/LSB sensitivity. The extreme low power capabilities of the MMA8491Q reduce the low data rate

current consumption to less than 400 nA per Hz.

Pin Definition of Connectors

This section will briefly introduce the connectors used on sensor board and the pins of these connectors in terms

of definition, function and application.

Demonstration

After the driver code is loaded onto the Freedom KL25Z, the sensor features can be demonstrated with a

command line interface of HyperTerminal, or another UART tools.

Setup and Configuration

1.

Plug in a USB cable from a USB host to the OpenSDA mini-B USB connector of the FRDM-KL25Z. The FRDM-

KL25Z will be powered by this USB connection. FRDM-KL25Z comes with the mass-storage device (MSD) Flash

Programmer OpenSDA Application preinstalled. It will appear as a removable storage drive with a volume

label of

FRDM-KL25Z. (

Note: For more details on setup of the FRDM-KL25Z please refer to

http://www.element14.com/community/docs/DOC-49219)

2. Open the FRDM-KL25Z drive

,

and drop the image “sensors_freedom.srec” into it, as seen below.

3. The MSD Flash Programmer also includes a USB virtual serial port which requires an

.INF

file for proper

installation in Windows. The necessary

.INF

file is available as part of the P&E OpenSDA USB Drivers and on

the

FRDM-KL25Z

removable drive.

The serial port will be configured after the driver installation

– eg. COM6 in the example.

5. Reset the board

by pressing the reset button (SW1)

, and you can see the information displayed below

6. Type 'S0' into the terminal

through the PC keyboard, to try out the MPL3115A2 sensor. The terminal will

begin to display temperature readings. Touch the sensor with your finger and notice that the temperature

readings will start to rise. At the same time, the RGB LED will begin blinking red.

MAG3110 sensor. Shake the board around, and you can see the 3-D magnetic field measurement change. At

the same time, the RGB LED will begin blinking green.

ESD PRECAUTIONS AND PROPER HANDLING PROCEDURES

This section includes the precautions for mechanical handling and static precautions to be taken to avoid ESD

damage:

 Avoid carpets in cool, dry areas. Leave development kits in their anti-static packaging until ready to be

installed.

 Dissipate static electricity before handling any system components (development kits) by touching a

grounded metal object, such as the system unit unpainted metal chassis.

 If possible, use antistatic devices, such as wrist straps and floor mats.

 Always hold a evaluation board by its edges. Avoid touching the contacts and components on the board.

 Take care when connecting or disconnecting cables. A damaged cable can cause a short in the electrical

circuit.

 Prevent damage to the connectors by aligning connector pins before you connect the cable. Misaligned

connector pins can cause damage to system components at power-on.

 When disconnecting a cable, always pull on the cable connector or strain-relief loop, not on the cable

itself.
