You can test the latest firmware changes with this:

var Particle = require("../lib/particle"); var board = new Particle({ token: process.env.PARTICLE_TOKEN, deviceId: process.env.PARTICLE_DEVICE_ID, });

board.on("ready", function() { var values = []; Array.from({length: 8}, (_, index) => { values.push(0); this.pinMode(D${index}, this.MODES.INPUT); this.digitalRead(D${index}, function(value) { values[index] = value; }); });

setInterval(function() { console.log(values.join("-")); }.bind(this), 100); }); — Reply to this email directly or view it on GitHub.
