Support for FXLS8961AF Accelerometer Calibration

Hello Team,

We are currently working with the FXLS8961AF - 3-Axis Low-g Accelerometer on the MK22FN512 evaluation board. However, we are experiencing difficulties testing the accelerometer's functionalities, particularly with sensitivity calibration.

We are using the following tools:

1. FREEMASTER 3.2 Debug GUI

2. FreeMASTER_Sensor_Tool

3. FXLS8961AF - 3-Axis Low-g Accelerometer on the MK22FN512 evaluation board

Could you please provide us with the procedure for calibrating the accelerometer's sensitivity, as well as guidance on its other functionalities? Additionally, if you have any training videos or example codes, that would be extremely helpful.

Please refer to the attached setup image for more context.

Kindly provide the required details ASAP. Thank you for your assistance.

Hello @Anilpatil_SasvaAuto ,

Thanks for your post. Here are some materials I found that might be helpful to you:

FXOS8700CQ - Bare metal example project - NXP Community

AN4069, Offset Calibration of the MMA8451, 2, 3Q - Application Notes

AN12760, Temperature compensation of accelerometer sensors measurement, application note

Please noted this is a Kinetis channel, FXLS8961AF Accelerometer is beyond the scope of my support. I suggest you create a new post on Sensors - NXP Community. The supporters will assist you further.
