GrovePi

Use the GrovePi and sensors in Elixir on a Raspberry Pi. If you have a Beaglebone Green or other port that has direct access to sensors (rather than going through a GrovePi), take a look at nerves_grove. This library will likely go through many changes in the coming months and possibly get merged into nerves_grove should there be enough overlap.

Installation

If available in Hex, the package can be installed by adding grovepi to your list of dependencies in mix.exs:

def deps do
  [{:grovepi, "~> 0.1.0"}]
end

But for now, add this:

def deps do
  [{:grovepi, github: "fhunleth/grovepi", branch: "master"}]
end

GrovePi uses elixir_ale for I2C communication. On some platforms elixir_ale does not compile so you may need to configure a stand in. Due to this limitation elixir_ale is not included except in the production environment. If you need it outside of production be sure to add it to your dependencies.

def deps do
  [
   {:grovepi, "~> 0.1.0"},
   {:elixir_ale, "~> 0.6"},
  ]
end

If you would like to use a stub in your tests you can configure a module to be used for I2C in you configuration.

  config :grovepi, :i2c, MyI2C
