Overview

This library runs TensorFlow machine learning models on microcontrollers, allowing you to build AI/ML applications powered by deep learning and neural networks.

With the included examples, you can recognize speech, detect people using a camera, and recognise "magic wand" gestures using an accelerometer.

The examples work best with the M5StickC(ESP32) board, which has a microphone and accelerometer.

Examples

hello_world

Outputs sine waves to serial outputs and build-in LEDs.

micro_speech

This is a sample of speech recognition. The audio_provider and command_responder must be modified according to the environment in which they are used.

person_detection

It is a person detection using a camera. The image_provider and detection_responder must be modified according to the environment in which they are used.

OldExamples

This is a sample for older versions. It will not work as it is.

magic_wand

This is gesture recognition using acceleration. The accelerometer_handler and output_handler must be modified according to the environment in which they are used.

magic_wand_*

A sketch customized to look like a specific board.

micro_speech_*

person_detection_ESP32-Camera

It is a person detection using a camera. This is a sample of using the ESP32 camera driver. Please configure the device you want to use in config.h.
