All, Twitter traffic revealed a need for PDF versions of the sensor fusion documentation.  Apologies for any inconvenience.  Our standard documents are in Word format (we make extensive use of the equation tools in Word), and we supply them in that same format to make it easy to reuse the material.  But for those who do not have Word, please see the attached PDF. Regards, Mike

Issue Using the STB GUI for eCompass kits RD4247MAG3110 and RD4247FXOS8700 only -- v6.1.0.1 on a machine that does not have the Adobe Flash Player ActiveX program installed may run into the following error after pressing the eCompass button: Solution Install the Adobe Flash Player + ActiveX from Adobe. Let us know if you are facing any other issues with the STB GUI v6.1.0.1. Regards, Tomas

This is a pre-release .msi installer for the Freescale Sensor Fusion Toolbox for Windows NEXT RELEASE.  This (or a later copy) will eventually replace the release copy at http://www.freescale.com/sensorfusion.  Altough this is a preview copy, it is believed stable.  Please let us know of any issues seen.  This version has a nice feature in that it can re-flash your Freedom board (KL25Z, KL26Z, KL46Z, K20D50M and K64F) with the matching firmware.  The new feature is under the File->Flash menu item.  There have also been some nice changes made to the "Magnetics" view.

Here's a zip file which incorporates the patch I outlined in my previous posting.

The attached is a preview copy of build 422 of the sensor fusion library, which is currently being tested by the Freescale Sensor's team. Please consult the docs/Release_Notes.txt file for changes from build 420, as well as known errata.

For those of you who do not have access to Google Play, here is the latest .apk file for the Android version of the Sensor Fusion Toolbox.  This version should trap problems which caused previously reported crashes.  There are no visible changes to the functionality.   IF you have access to Google Play, we recommend that you use that as your default installer, as you can automatically get updates.

The Sensor Fusion Toolbox for Android includes a feature illustrating how an air mouse might be implemented on top of the Freescale sensor fusion library.  That tool includes documentation which discusses the algorithm.  That documentation is replicated on the MEMS Industry Group GitHub site.  It's been pointed out that this could use a couple additional diagrams to illustrate the geometry behind the calculations.  For that, please see the attached. BTW, The preview below has been somewhat corrupted by the blogging platform.  I suggest you download the powerpoint file before viewing.

My friend Matt Muddiman of Freescale gave this presentation as part of the MEMS Education Series (hosted by Arizona Technology Council and MEMS Industry Group) in Scottsdale Arizona earlier this week.

You will have to add a .exe extension to the unzipped file.

The following video shows how to run the FRDM 6DOF Bare Board eCompass using the FRDM-K22. This algorithm uses the FXOS8700 contained on the Freedom Board. In order to get more information about the Sensor Fusion Library for Kinetis MCU's 5.0, please refer to the following link: Sensor Fusion|Freescale I hope this material will be useful for you. David

The MMA690x, a SafeAssure solution, is a dual axis, Low g, XY, Sensorbased on Freescale’s HARMEMS technology, with an embedded DSP ASIC, allowing for additional processing of the digital signals. Here is a Render of the MMA690x Breakout Board downloaded from OSH park: Layout Design for this board: In the attachments section, you can find the Schematic Source File (SCH), Schematic PDF File, Layout Source File (BRD), Gerber Files (GTL, GBL, GTS, GBS, GTO, GBO, GKO, XLN) and BOM files.   If you're interested in more designs like this breakout board for other sensors, please go to Freescale Sensors Breakout Boards Designs – HOME

All, Drop the attached into SDK_2.0_FRDM-KL25Z/boards/frdmkl25z_virtual_shield/issdk_examples/algorithms/sensorfusion/baremetal_sensor_fusion. Apologies for both the delay in posting and the fact that even though I thought I was linking to files elsewhere in the system, I ended up getting local copies built into this project.  Some of you may like that.  I don't particularly.  But as I've noted elsewhere, KDS and I have our differences... Regards, Mike

This is the 9 December 2014 build of Vibration Monitoring program written by Mark Pedley in the Sensors Solutions Division systems/algorithms team.  It is compatible with Freescale FRDM-KL25Z/KL26Z/KL46Z/K64F Freedom development platforms.  You can flash your board using the File->Flash pull-down menu.    The application contains an option for controlling motor bias and feedback via optional motor control shield to be discussed in an upcoming Freescale blog.  Use the View->Motor Controls pull-down to enable those functions.

The attached is the windows installer for the latest verson of the Windows version of the Freescale Sensor Fusion Toolbox.  This version must be used with Version 5.00 of the sensor fusion library.  It is NOT backward compatible, as the structure of the undocumented Kalman filter packet has changed. Please uninstall any prior versions of the toolbox before running this installer. As in prior releases, you can reflash your Freedom boards from within the application itself.  So if you want to try the new fusion without downloading the new library and firing up KDS or CodeWarrior, you can. Version 5.00 was posted to this same board just a few minutes ago in a separate post.  It contains full documentation, including algorithm development, datasheet and user guide. Regards, Mike Stanley

Attached is a PDF dump of a classic blog post.  Please forgive the format problems.  I'll work with the web team in January to get it reposted to the NXP site. Mike
