TensorFlow-Lite and Platform.io

This repo demonstrates how to use a TensorFlow model on the ESP32 using Platform.io.

There's a walkthrough video here: https://youtu.be/kZdIO82059E

Setup

To train the model you'll need a python environment. Make sure you have python 3 installed on your system:

python3 --version

Then run the following command to create a virtual python environment.

python3 -m venv venv

Activate the environment using:

. ./venv/bin/activate

And install the dependencies using:

pip install -r requirements.txt

Training the model

Make sure you have activated the virtual environment using:

. ./venv/bin/activate

Then run:

jupyter notebook .

Open up the train_model notebook and follow the instructions in the notebook.

Once you've trained and converted the model run:

xxd -i converted_model.tflite > firmware/src/model_data.cc

You can then open up the platform.io project in firmware folder and try it out.
