Off. 4 XTRINSIC- SENSE Board Evaluation board for Freescale Xtrinsic Sensors Doc ID: XTRINSICRPIUM Rev. 0.4, 01/09/2014 Kit Overview The XTRINSIC-SENSE board demonstrates the capabilities of Freescale's Xtrinsic sensors. The Xtrinsic Sensor board includes interfacing and support for the following host platforms: * * Freescale FRDM-KL25Z Raspberry Pi (Model B) 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 Sense Board Quick Start Guide Xtrinsic Sense Board The sensor board comes equipped with three of Freescale's new-generation XTRINSIC MEMS sensors. The MPL3115 (U1) is designed for accurate measurement of temperature and pressure, the MAG3110 (U2) for detection of magnetic fields, and the MMA8491 (U3) for measurement of physical positions. Figure 1 - Sensor Board XTRINSIC- SENSE Board Evaluation board for Freescale Xtrinsic Sensors Doc ID: XTRINSICRPIUM Rev. 0.4, 01/09/2014 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.

(Note: For more details on setup of the FRDM-KL25Z please refer to http://www.element14.com/community/docs/DOC-49219) USB connection 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 instructions include details on how to manually update an official RPi image to support the same terminal and web applications demonstrations detailed in steps 5 thru 21 above. This section assumes user knowledge on accessing an official RPi image and programming it to Flash. This detail is NOT covered in this document. Set-up 22. Follow step 1, 3 and 4 in the previous section to set-up, connect, and power the Raspberry Pi with XTRINSIC-SENSE BOARD. Terminal tests The XTRINSIC-SENSE BOARD communicates with the Raspberry Pi using the I2C interface. The I2C interface driver is included in later Raspbian distributions but is not enabled by default. You can always enable the I2C driver, or you can load it by hand when required. To always enable the I2C driver: 23. After logging into RPi, edit /etc/modprobe.d/raspi-blacklist.conf by typing: $ sudo nano /etc/modprobe.d/raspi-blacklist.conf 24. Insert a hash(#) at the start of the line blacklist i2c-bcm2708, it should be read: # blacklist i2c-bcm2708 Alternatively, to load the I2C driver by hand (will not be loaded on reboot): Ctrl-X to save 25. Type in a terminal: $ sudo modprobe i2c-bcm2708 26. Next, you need to install the sensor drivers. Download the driver and python test scripts from: git clone http://git.oschina.net/embest/rpi_sensor_board.git 27. When the downloading finished, reboot your Raspberry Pi: $ sudo reboot 28. Then you can test the sensor from terminal. Refer to steps 5 thru 7 above to run terminal demonstration tests. Embest and element14 are trademarks of Premier Farnell plc (c) 2014 Premier Farnell plc.

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. Embest and element14 are trademarks of Premier Farnell plc (c) 2014 Premier Farnell plc.
