Firmata.js altogether with browserify can't access or recognize the Serial Port:

kevinmamaqi commented 7 years ago

On my mac I connect arduino and run: ls /dev/tty.* // Find Serial Port number and name. /dev/tty.Bluetooth-Incoming-Port /dev/tty.usbmodem1421

Then on my main.js (before bundling with browserify) I have the following:

var Board = require("firmata");
var board = new Board("/dev/tty.usbmodem1421)");

  board.on("open", function() {
    console.log("  ✔ open");
  });

/*board.on("ready", function() {
    // Arduino is ready to communicate
    this.analogRead(0, function(value) {
      console.log("The value of pin A0 is " + value + " as reported at the sampling interval");
    });
});*/

Get the following message: Uncaught Error: No access to serial ports. Try loading as a Chrome Application.

Are you trying to run this in a non-Electron, non-NW.js browser?

kevinmamaqi commented 7 years ago

I think so, I was using chrome. Not aware of what non-NW.js browsers are.

@kevinmamaqi Chrome doesn't have access to the filesystem, device descriptor or USB port you're trying to use. Browserify cannot help you with this as it's a browser security limitation causing this problem.
