Carica Io is a collection of experimental php classes and scripts for non-blocking I/O. It provides the basic building blocks for hardware control using Firmata (Arduino) and GPIO (Raspberry PI)., _(*4)

Basics

The repository provides the API needed for non-blocking I/O. A simple event loop and event emitter are included. The loop implementation is not performance optimized. However it is possible to use an adapter for ReactPHP or AMPHP., _(*5)

It includes an (incomplete) HTTP server that should be enough for the first steps. It supports GET requests and WebSocket connections., _(*6)

Carica/Io provides the classes for event based programming and a simple web server. It defines interfaces for hardware control (Pin, ShiftOut, ...). Carica/Firmata is a client library for the Firmata protocol it allows to control Arduino boards over a serial or a network connection. Carica/GPIO implements GPIO into PHP using the file system or the WiringPI library for the Raspberry PI., _(*7)

Carica/Chip implements classes for hardware objects. Like a LED, a RGB-LED, a Servo,..., _(*8)

Usage

You will need to get the loop instance from the factory, attach events and run it., _(*9)

$loop = Carica\Io\Event\Loop\Factory::get();
$loop->setInterval(
  static function () {
    static $i = 0;
    echo $i++;
  },
  1000
);
$loop->run();
