Sensor Toolbox glitch

Hi,

I have the MMA865xFC accelerometers evaluation board, and I'm playing with the Sensor Toolbox software.

I notice that all the Green/Red led-like icons are NOT visible (the space is empty) anywhere. I tried the last version of the program on multiple operating systems (Win8, Win7, WinXP) but nothing changes.

A screenshot is attached.

Is that a bug or what ??

Cheers

Hi Andrea,

We apologize for this issue that is caused by a missing file in the installer.

The fix is:

1. Navigate to the “C:\Program Files\Freescale\Sensor Toolbox” folder
2. Open the “MMA955x” Folder
3. Copy the file “Mesa.dll”
4. Return to the Sensor Toolbox folder and open the “MMA845xQ” folder
5. Paste the “Mesa.dll” file

Regards,

Tomas

Thanks, now it works.

Now I'm just playing with free fall/motion stuff and doing some research on that topic. Can I ask you if Freescale has some implementation suggestion about techniques to detect human fall, maybe combining FF and motion interrupts instead of using the bare interrupt method ??

I have already found some solutions on the net, maybe Freescale has done some research on this topic on their own.

Thanks again,

Cheers

Hi Andrea,

Human fall movement is a very complicated behavior which differs with various scenarios, people’s action mode and even their ages. I suppose that a variety of built-in features of the MMA865xFC accelerometers, including motion/freefall detection, transient detection and flexible interrupts, could simplify implementation of human fall detection algorithms, but I currently do not have any specific code examples to share, unfortunately.
