Quaternion Visualization

This example directory contains sample code demonstrating how to use the ns-features library. It includes usage examples for computing quaternion values and extracting features from sensor data.

Real-time Orientation Display Script

Additionally, the example provides a Python script for displaying the orientation of the sensor in real time. This script utilizes the quaternion values computed by ns-features to visualize the orientation of the sensor graphically.

Installation and Setup

Before using the examples, ensure you have the necessary Python-based PC-side software installed by following the instructions here..

Note for Windows Users: If you are using Windows, refer to our Windows eRPC application note for additional instructions.

Additionally, make sure you have the following Python libraries installed:

pip install numpy numpy-quaternion matplotlib

Required Hardware and Configuration

This example is requires the following hardware: * Apollo510 EVB * ICM-45605 Mikroe Board (MIKRO-6040) installed in EVB's Clickboard slot * J13 jumper selecting 3.3v * USB connection between EVB USB_AP5 port (J18) and laptop

Running the Example

Once the above is installed, the following steps are needed to run the example: 1. Compile and flash the example (optionally, start the SWO viewer) 2. Start the visualization script 3. Press Button 0 on EVB

Compile, Deploy, and View SWO

$> cd .../neuralSPOT
$> make -j EXAMPLE=examples/quaternion deploy
$> make view

Start the Visualization Script

$> cd .../neuralSPOT/examples/quaternion/source
$> python quaternion_plotter.py

At this point, the script will ask you to press the EVB button and wait for calibration, whereupon it will launch the visualizer.
