# Hello World Example
This example is designed to demonstrate the absolute basics of using [TensorFlow
Lite for Microcontrollers](https://www.tensorflow.org/lite/microcontrollers).
It includes the full end-to-end workflow of training a model, converting it for
use with TensorFlow Lite for Microcontrollers for running inference on a
microcontroller.
The model is trained to replicate a `sine` function and generates a pattern of
data to either blink LEDs or control an animation, depending on the capabilities
of the device.
## Deploy to ESP32
The sample has been tested on ESP-IDF version `release/v4.2` and `release/v4.4` with the following devices:
- [ESP32-DevKitC](http://esp-idf.readthedocs.io/en/latest/get-started/get-started-devkitc.html)
- [ESP32-S3-DevKitC](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/hw-reference/esp32s3/user-guide-devkitc-1.html)
- [ESP-EYE](https://github.com/espressif/esp-who/blob/master/docs/en/get-started/ESP-EYE_Getting_Started_Guide.md)

The example sketches include "tensorflow/lite/micro/micro_interpreter.h" which internally include "utility.h" header file when compiling examples for Arduino (when -DARDUINO flag is passed to the compiler). This header file does not exist in esp32-arduino core. Hence, keeping this file here as a workaround and including an alternate header file.
