# Elixir MLX90640

[![Build Status](https://travis-ci.org/lucaong/elixir_mlx90640.svg?branch=master)](https://travis-ci.org/lucaong/elixir_mlx90640)

An Elixir library to interface with the MLX90640 Far Infrared Thermal Sensor Array.

An example of a project using this library is [Nerves Thermal

Camera](https://github.com/lucaong/nerves_thermal_camera).

## Installation

The package can be installed by adding `elixir_mlx90640` to your list of

dependencies in `mix.exs`:

```elixir

def deps do

  [

    {:elixir_mlx90640, "~> 0.1.13"}

  ]

end

```

The I2C driver needs to be installed for this library to compile (e.g.

`libi2c-dev` on Debian).

## Usage

```elixir

receiver = self() # a process that will receive the data frames

Mlx90640.start_link(receiver, [ frame_rate: 2 ])

# On each frame, the receiver will receive messages like:

#

#   %Mlx90640.Frame{ data:

#     [

#       [ 23.83, 24.12, 20.69, ... ],

#       [ 20.36, 20.74, 20.71, ... ],

#       ...

#     ]

#   }

#

# Where data is a list of 24 rows, and rows are lists of 32 temperature

# measurements

```
