firmata 0.0.1

Dart Implementation of Firmata

#Firmata

Dart Implementation of Firmata

Current status : in dev

Currently working :

• Connexion to Arduino
• Digital write
• Digital read

Install

Firmata needs serial_port lib. To install it, easily, just run bin/install.sh

Samples

• Blink

// Example from https://github.com/jgautier/firmata/blob/master/examples/blink.js

import 'package:firmata/firmata.dart';
import 'dart:async';

final ledPin = 13;

main() {
  print('blink start ...');
  final board = new Board('/dev/cu.usbmodem1421');
  board.open().then((_) {

    print("connected");
    print('Firmware: ${board.firmware.name}-${board.firmware.major}.${board.firmware.minor}');

    var ledOn = true;
    board.pinMode(ledPin, Modes.OUTPUT);

    new Timer.periodic(new Duration(milliseconds: 500), (_) {
      if (ledOn) {
        print("+");
        board.digitalWrite(ledPin, Board.HIGH);
      } else {
        print("-");
        board.digitalWrite(ledPin, Board.LOW);
      }
      ledOn = !ledOn;
    });

  }).catchError((error) => print("Cannot connect $error"));
}

• Play with buttons and leds.

final P2 = 3;
final L1 = 4;

  final board = new Board('/dev/tty.usbserial-A92TDN3B');

    board.pinMode(L1, Modes.OUTPUT);

    board.pinMode(L3, Modes.OUTPUT);
    board.pinMode(L4, Modes.OUTPUT);
    board.pinMode(P1, Modes.INPUT);
    board.pinMode(P2, Modes.INPUT);

    board.onDigitalRead.listen((pinState){
      if(pinState.pin == P1){
        board.digitalWrite(L1, pinState.value);
        board.digitalWrite(L2, pinState.value);
      } else {
        board.digitalWrite(L3, pinState.value);
