GrovePi

Build Status

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.

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, "~> 0.5.1"}]
end

The grovepi library uses Elixir Circuits - I2C for I2C communication to the GrovePi+. This only works on Raspberry Pi computers. If you're working on another platform, a stub is available for debugging and testing. When building grovepi standalone, be aware that circuits_i2c is only used for MIX_ENV=prod builds. To use the stub in your own programs, add the following to your configuration:

  config :grovepi, :i2c, GrovePi.I2C

API Documentation

Contributions

We welcome contributions to tackle issues in GrovePi.

Setup

First fork the repository and fetch your own copy

mix deps.get
mix test

Submitting a Pull Request

  1. Fork the repository.
  2. Create a topic branch.
  3. Add tests for your unimplemented feature or bug fix.
  4. Run mix test. If your tests pass, return to step 3.
  5. Implement your feature or bug fix.
  6. Run mix test. If your tests fail, return to step 5.
  7. Commit, and push your changes.
  8. Submit a pull request.

Running Tests

All tests can be run with mix test or a single test file can be run with mix test path/to/file_test.exs.

If you would like tests to run in the background as you change files you can run mix test.watch.

You can’t perform that action at this time.
