Device Grove Service

About

The EdgeX Device Grove Service is developed to control/communicate Grove sensors connected on Grove PI in an EdgeX deployment

Supported Boards:

Raspberry PI 3+ - ARM64 bit

Dependencies:

The Device Grove service based on device-c-sdk is developed using libmraa - a low level library that communicates with the Raspberry PI board. The repository can be found on git at libmraa.

Build Instruction:

1. Check out device-grove-c available at device-grove-c

2. Build a docker image by using the following command

sh> cd device-grove-c
sh> docker build . -t < device-grove-c > -f ./scripts/Dockerfile.alpine-3.9

This command shall build the dependencies - libmraa and device-c-sdk library to build device-grove-c release image. By default, the configuration and profile file used by the service are available in 'res' folder.

Configuration for docker image

1. Port number specified in the configuration.toml
2. --device=/dev/ < i2c-device > to map host device to the container. For Raspberry PI, it is i2c-1.

Note: On Raspberry PI, make sure that i2c_arm=on is set. This enables i2c-1 device, required for communication between Grove PI & Raspberry PI boards.
