# Elixir MLX90640

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

## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `elixir_mlx90640` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:elixir_mlx90640, "~> 0.1.2"}
  ]
end
```

## 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
```
