RT1170 Example of accelerometer

[dskim2]

Hi

I have an RT1170 EVK board.
I looked for accelerometer demo source in MCUXpresso IDE, but it doesn't seem to be there.

Where can I get the demo sources?

Best Regards

Hi @dskim2 ,

Thanks for contacting NXP tech support!

Could you describe in more detail the demo you are looking for? For graphics acceleration or something else?

Best regards,
Gavin

Looking at the demo board circuit diagram, FXLS8974CFR3 is installed, I need a demo source that can use this accelerometer device.

Hi @dskim2 ,

The examples in the current SDK do not include a demo that uses this accelerometer, but provide component implementations: SDK_2_15_000_MIMXRT1170-EVK\components\fxls8974cf

Other than that, here's a project that implements a driver for it that should help you, I've packaged it up as an MCUXpressoIDE project for you to check out in the attach files, the original link is here: https://github.com/nxp-appcodehub/ap-ml-state-monitor/tree/main

Hope it helps!

Best regards,
Gavin

I downloaded this sample project to be used with MIMXRT1170-EVKB which has the same sensor according to the HW Guide:

MIMXRT1170EVKBHUG
MIMXRT1170 EVKB Board Hardware User Guide
Rev. 4 — 11 June 2024

2.16 Sensor
U115 on the EVK board is a 3-axis MEMS accelerometer. Sensor FXLS8974CFR3.

When I run the project I am getting this in Terminal: 

Starting Application:
CPU: 996000000 Hz
Application version: 1.0.0
MPP version: MPP_VERSION_1.0.0
Inference Engine: TensorFlow-Lite Micro

FXLS8974 Sensor Initialization Failed
Failed to add accelerometer Fxls8974
Error building application pipeline : ret 3

Does EVKB board requires some different settings for the Fxls8974?

Thanks for your reply

When I ran the source in MCUXpresso for debugging, the following error occurred.
How can I solve this?

Hi @dskim2 ,

This demo is working and was able to build successfully on my end. But debug requires additional hardware. So you can adopt it as a reference implementation for an accelerometer driver. It should fit your needs.
