unable to find Step Count using FRDM-KL25Z

Hi All,

I was looking for a similar example mentioned in the below link for the step counter.

https://community.nxp.com/t5/Sensors/Fall-Detection-and-Step-Count-using-FRDM-KL25Z/m-p/767328/highlight/true#M4964

Shubhadip did mention there is an example named "pedometer_mma8451" but I am unable to find it in SDK_2.2.0_FRDM-KL25Z. I am attaching a screenshot of an example I am seeing under "issdk_examples"

Where can I get the source for "boards\frdmkl25z\issdk_examples\algorithms\pedometer\pedometer_mma8451"?

Hi Jayesh,

Please have a look at your downloaded SDK archive, you should find it there if you selected "NXP IoT Sensing SDK" while building the SDK for FRDM-KL25Z:

Best regards,

Tomas

@TomasVaverka Thank you for replying.

I am seeing similar files and I have opened them up but I am not seeing any relevant source in those files. Can you point me to files that have accelerometer-related API as well as algorithms for the step counter?

Hi Jayesh,

It seems they are only available for a custom kit with FRDM-STBC-AGM01 such as FRDM-K64F/FRDM-K22F and FRDM-STBC-AGM01.

Best regards,

Tomas
