Gpio Bundle

A Symfony2 bundle to operate with raspberry pi gpio pins

Features include:

• Easy IO pin configuration (add humanized slugs instead numbers)
• Command to setup pins from configuration to raspberry file system
• Watch command to listen input status changes
• Command to read input pin status and set output pin status
• Configure Symfony events to be triggered on input pin status change

Installation

GpioBundle is available on Packagist (notrix/gpio-bundle) and is installable via Composer.

php composer.phar require notrix/gpio-bundle 'dev-master'

Configuration

Possible configuration options are listed below

# app/config/config.yml
notrix_gpio:
    sudo: true # Run commands with sudo permissions for raspberry
    development: false # true will use fake raspberry lib to imitate getting and setting pin statuses
    watcher_interval: 0.35 # how often poll input files for status changes
    in: # here you can configure input pins
        18: # this is rasperry's internal pin number 
            slug: pir_sensor1 # your custom slug to identify pin
            event: { on: pir_sensor_on, off: pir_sensor_off } # symfony event names. You can attach an event listeners to them
        23:
            slug: pir_sensor2
            event: [ pir_sensor_triggered ] # one event on both statuses on and off
    out: # here you can configure output pins
        17:
            slug: blue_led # slug to identify current pin
        22:
            slug: red_led

Note: As this bundle has a dependancy on ronanguilloux/php-gpio development lib version, your project minimum stability has to be 'dev' or include this vendor as a dependancy to your project with @dev stability flag

Usage

You should allways use manager service 'notrix_gpio.pin_manager' to controll your pins.

Write Event listeners for input pins.

Run 'php app/console notrix:gpio:setup' to initialize pins

Run 'php app/console notrix:gpio:watch -vv' to see how symfony reacts to pin status changes and with no '-vv' to run it quietly and do the listeners job.
