TensorFlow Lite sample application
==================================

This application is taken as-is from the hello-world sample
application of TensorFlow Lite for microcontrollers.

The original code is
[available on GitHub](https://github.com/tensorflow/tensorflow/tree/master/tensorflow/lite/experimental/micro/examples/hello_world).

This application simply replicates a `sine` function from a trained model.

To get started with TensorFlow Lite on microcontrollers, please refer to
[this page](https://www.tensorflow.org/lite/microcontrollers).

Usage
-----

Simply run the application on the board of your choice using:

    make BOARD=<board of your choice> -C tests/pkg_tensorflow-lite flash term

Then type 's' to start the application.

Expected result
---------------

The application prints the values of the `sine` function:
```
