Edge Impulse on MSP432 using accelerometer data

Help
#1

I was going through the tutorial for getting the inferencing lib to run on the MSP432.
However, I came across this error which stumped me a little:

Edge Impulse standalone inferencing (Arduino)
The size of your ‘features’ array is not correct. Expected 150 items, but had 0

When I tested using the “Live classification”, it works. However, when I exported it and download the Arduino code generated by the tool onto the MSP432, it throws me the above error.

What am I doing wrong?

Hi @sirfonzie, I would start by checking: https://docs.edgeimpulse.com/docs/running-your-impulse-arduino and see if you can copy the raw features from your project from one of the data samples into the features array just to test that the whole inferencing pipeline is working.

Hi, are you using the example from this repo here? https://github.com/edgeimpulse/example-ti-msp432-mcu-motion

Yup. I am using this repo.
