how to run at command through chrome serial api

how to run at command through chrome serial api - javascript

i want to run at command at my hardware thorugh crome serial api
I use this Opensource code
https://github.com/GoogleChrome/chrome-app-samples/tree/master/servo
this working only for only integer
i want to pass string in the serial port my code is like following
var connectionId = -1;
function setPosition(position) {
var buffer = new ArrayBuffer(1);
var uint8View = new Uint8Array(buffer);
uint8View[0] = '0'.charCodeAt(0) + position;
chrome.serial.write(connectionId, buffer, function() {});
};
function setTxt(data) {
// document.getElementById('txt').innerHTML = data;
var bf = str2ab(data)
chrome.serial.write(connectionId, bf, function() {});
};
function str2ab(str) {
len = str.length;
var buf = new ArrayBuffer(len*2); // 2 bytes for each char
var bufView = new Uint16Array(buf);
for (var i=0, strLen=str.length; i<strLen; i++) {
bufView[i] = str.charCodeAt(i);
}
return buf;
}
function onRead(readInfo) {
var uint8View = new Uint8Array(readInfo.data);
var value1 = String.fromCharCode(uint8View[0])
var value = uint8View[0] - '0'.charCodeAt(0);
var rotation = value * 18.0;
// var dataarr = String.fromCharCode.apply(null, new Uint16Array(readInfo.data));
//alert(rotation);
if(uint8View[0])
document.getElementById('txt').innerHTML = document.getElementById('txt').innerHTML + value1;
document.getElementById('image').style.webkitTransform =
'rotateZ(' + rotation + 'deg)';
// document.getElementById('txt').innerHTML=uint8View[0];
// Keep on reading.
chrome.serial.read(connectionId, 1, onRead);
};
function ab2str(buf) {
return String.fromCharCode.apply(null, new Uint16Array(buf));
}
function onOpen(openInfo) {
connectionId = openInfo.connectionId;
if (connectionId == -1) {
setStatus('Could not open');
return;
}
setStatus('Connected');
setPosition(0);
chrome.serial.read(connectionId, 1, onRead);
};
function setStatus(status) {
document.getElementById('status').innerText = status;
}
function buildPortPicker(ports) {
var eligiblePorts = ports.filter(function(port) {
return !port.match(/[Bb]luetooth/);
});
var portPicker = document.getElementById('port-picker');
eligiblePorts.forEach(function(port) {
var portOption = document.createElement('option');
portOption.value = portOption.innerText = port;
portPicker.appendChild(portOption);
});
portPicker.onchange = function() {
if (connectionId != -1) {
chrome.serial.close(connectionId, openSelectedPort);
return;
}
openSelectedPort();
};
}
function openSelectedPort() {
var portPicker = document.getElementById('port-picker');
var selectedPort = portPicker.options[portPicker.selectedIndex].value;
chrome.serial.open(selectedPort, onOpen);
}
onload = function() {
var tv = document.getElementById('tv');
navigator.webkitGetUserMedia(
{video: true},
function(stream) {
tv.classList.add('working');
document.getElementById('camera-output').src =
webkitURL.createObjectURL(stream);
},
function() {
tv.classList.add('broken');
});
document.getElementById('position-input').onchange = function() {
setPosition(parseInt(this.value, 10));
};
document.getElementById('txt-input').onchange = function() {
setTxt(this.value);
// document.getElementById('txt').innerHTML = this.value;
};
chrome.serial.getPorts(function(ports) {
buildPortPicker(ports)
openSelectedPort();
});
};
string is the passing through serial but this command not run without enter press how to do it any one know
thanks in advance :)

need a \n at the end of string
example:
writeSerial( '#;Bit_Test;*;1;' + '\n' );
take a look at this project http://www.dataino.it/help/document_tutorial.php?id=13

Duplicate data google apps script and javascript on upload files

I have a web app with GAS that create folders, upload files, set permissions and save the registers on a sheet.
Ocassionally the app duplicate files when the functions finished and duplicate a register in the google sheet. I don't know how to avoid this error, and the console does not show the error either.
What could be happening? How can I prevent this problem?
This is my code for server side functions:
function fileExists(idfileexist,folderId) {
var consulta = DriveApp.getFileById(idfileexist).getName()
var files = DriveApp.getFilesByName(consulta);
while (files.hasNext()) {
var file = files.next();

}
}
}
return false;
}

Greetings and Thank You!

My old method it was very "heavy". When i set the permission to the folder and files, i had to call a lot of times the Driver API and the services. Other problem it was that the parent folder had a lot of folders and many files which made it take a long time to set the permissions to the user or revocate permissions.
My new method was create a folder with edit permission for the users and move the files and folder to the destiny folder for other users. My objetive was set the correct permissions for final users.This is my new code. The javascript's code doesn't have problems:
function moveFiles(sourceFileId, targetFolderId) {
var file = DriveApp.getFileById(sourceFileId);
file.getParents().next().removeFile(file);
DriveApp.getFolderById(targetFolderId).addFile(file);
}
function fileExists(idfileexist,folderId) {
var consulta = DriveApp.getFileById(idfileexist).getName()
var files = DriveApp.getFilesByName(consulta);
while (files.hasNext()) {
var file = files.next();
var folders = file.getParents();
if (folders.hasNext()) {
var folder = folders.next();
if (folder.getId() == folderId) {
return true;
}
}
}
return false;
}
function removepermission(id, user){
DriveApp.getFileById(id).removeEditor(user)
}
function appendrow(idfile,sheet,numsip,rut,timestamp,user,idfolder,exedoc,ticket){
var values = SpreadsheetApp.openById(idfile);
var ss= values.getSheetByName(sheet);
ss.appendRow([numsip,rut,timestamp,user,idfolder,exedoc,ticket])
}
function setpermisoswriter(id,array){
var file = DriveApp.getFileById(id)
var editors = file.getEditors();
if (editors.length > 0) {

Multithread node.js instagram parser

Working on node.js instagram parser. At the moment I have 1 thread with proxy working code, but I'm not sure how to make multithread architecture:
'use strict';
var InstagramPrivateAPI = {};
InstagramPrivateAPI = {};
InstagramPrivateAPI.V1 = require(__dirname + '/client/v1');
InstagramPrivateAPI.Helpers = require(__dirname + '/helpers');
var acc = require(__dirname + "/client/v1/account");
var med = require(__dirname + "/client/v1/media")
var Promise = require('../bluebird');
var _ = require('../lodash/');
module.exports = InstagramPrivateAPI;
var Client = require('instagram-private-api').V1;
var device = new Client.Device('maksgmn');
var storage = new Client.CookieFileStorage(__dirname + '/cookies/maksgmn.json');
var session = new Client.Session(device, storage);
function getRandomInt(min, max) {
return Math.floor(Math.random() * (max - min)) + min;
}
var fs = require('fs');
var proxyArray = fs.readFileSync('proxy.txt').toString().split("\n");
var usernamesArray = fs.readFileSync('usernames.txt').toString().split("\n");
var proxy = "http://" + proxyArray[getRandomInt(0,proxyArray.length)]
var username = usernamesArray[getRandomInt(0,usernamesArray.length)]
console.log(proxy)
console.log(username)
Client.Request.setProxy(proxy);
acc.searchForUser(session, username) //поиск id пользователя
.then(function(profile) {
return profile.id
})
.then(function(someId) { //получение промиса lenta
var feed = new Client.Feed.UserMedia(session, someId);
var lenta = Promise.mapSeries(_.range(0, 1), function() {
return feed.get();
}).then(function(lenta) {
return {id: someId, fd : lenta}
})
return lenta
})
.then(function(results) { //обработка промиса и получение ленты пользователя
// result should be Media[][]
var media1 = _.flatten(results.fd);
var urls1 = _.map(media1, function(medium) {
//var arr1 = medium.params.images[0].url;
var arr1 = []
try {
arr1 = medium.params.images[0].url
} catch (err) {
//console.log("lala")
}
return arr1;
//console.log(medium.params.carouselMedia.images[0].url)
})
//console.log(urls1)
return {id : results.id, linksNoCarousel : urls1, med : media1}
})
.then(function(res){
var urls2 = _.map(res.med, function(medium) {
var arr2 = []
try {
arr2 = medium.params.images[0][0].url
//console.log(arr2)
} catch (err) {
}
return arr2
})
for (var i = 0; i < 5; i++) {
if (typeof res.linksNoCarousel[i] == "undefined")
res.linksNoCarousel[i] = urls2[i];
}
var arr3 = []
for (var i = 0; i < 5; i++) {
arr3[i] = res.linksNoCarousel[i]
}
return {id : res.id, links : arr3}
})
.then(function(mediaAndId) {
acc = acc.getById(session, mediaAndId.id)
.then(function(account) {
//console.log(account.params)
let avatar = account.params.profilePicUrl;
let fullName = account.params.fullName;
let bio = account.params.biography;
let media0 = mediaAndId.links[0];
let media1 = mediaAndId.links[1];
let media2 = mediaAndId.links[2];
let media3 = mediaAndId.links[3];
let media4 = mediaAndId.links[4];
console.log(avatar);
console.log(fullName);
console.log(bio);
console.log(media0);
console.log(media1);
console.log(media2);
console.log(media3);
console.log(media4);
})
})
I would like it to work like multithread to be much more faster with proxies. As far as I'm working with node.js 2nd day, asking that question: how to do that?

How to decode only part of the mp3 for use with WebAudio API?

In my web application, I have a requirement to play part of mp3 file. This is a local web app, so I don't care about downloads etc, everything is stored locally.
My use case is as follows:
determine file to play
determine start and stop of the sound
load the file [I use BufferLoader]
play
Quite simple.
Right now I just grab the mp3 file, decode it in memory for use with WebAudio API, and play it.
Unfortunately, because the mp3 files can get quite long [30minutes of audio for example] the decoded file in memory can take up to 900MB. That's a bit too much to handle.
Is there any option, where I could decode only part of the file? How could I detect where to start and how far to go?
I cannot anticipate the bitrate, it can be constant, but I would expect variable as well.
Here's an example of what I did:

var MediaPlayerAudioContext = window.AudioContext || window.webkitAudioContext;

There is no way of streaming with decodeAudioData(), you need to use MediaElement with createMediaStreamSource and run your stuff then. decodeAudioData() cannot stream on a part.#zre00ne And mp3 will be decoded big!!! Verybig!!!

HTML5 IndexedDB - How to merge all records into one

My idea is download chunks a huge file from server.
Chunks stored into an IndexedDB.
After download all chunks, merge all records into one (as SQL SELECT * FROM XXX ...).
Save into disk "saveAs()" or create URL to IndexedDB...
(Or any idea?)
I do not know how to do step 2. and 3.
(Below is an example of storing 10,000 records in the DB and the expected output after step 2. should be SusanSusanSusanSusanSusan...)
if (transaction) {
transaction.oncomplete = function () {
}
transaction.onabort = function () {
writeToConsoleScreen("transaction aborted.");
localDatabase.db.close();
}
transaction.ontimeout = function () {
writeToConsoleScreen("transaction timeout.");
localDatabase.db.close();
}
var store = transaction.objectStore(osTableName);
if (store) {
var req;
var customer = {};
// create ten thousand records
for (var loop = 0; loop < 10000; loop++) {
customer = {};
customer.fname = 'Susan';
req = store.add(customer);
req.onsuccess = function (ev) {
}
req.onerror = function (ev) {
writeToConsoleScreen("Failed to add record." + " Error: " + ev.message);
}
}
}
}

<!DOCTYPE html>
<script>
var open = indexedDB.open('chunks-example');
open.onupgradeneeded = function() {
// Create schema if necessary
var db = open.result;
db.createObjectStore('chunks');
};
// 1. Chunks stored into an IndexedDB.
open.onsuccess = function() {
var db = open.result;
var tx = db.transaction('chunks', 'readwrite');
var store = tx.objectStore('chunks');
for (var i = 0; i < 10; ++i) {
// For realz, this would be via
// XMLHttpRequest.response and async.
var chunk = new Blob(['chunk ' + i + '\n'],
{type: 'application/octet-stream'});
store.put(chunk, i);
}
tx.oncomplete = function() { merge(db); };
};
// 2. After "download" all chunks, merge all records into one
function merge(db) {
var tx = db.transaction('chunks');
var store = tx.objectStore('chunks');
var chunks = [];
var request = store.openCursor();
request.onsuccess = function() {
var cursor = request.result;
if (cursor) {
chunks.push(cursor.value);
cursor.continue();
} else {
saveAs('myfile', new Blob(chunks,
{type: 'application/octet-stream'}));
}
};
}
// 3. Save into disk "saveAs()"
function saveAs(filename, blob) {
var a = document.documentElement.appendChild(document.createElement('a'));
a.href = URL.createObjectURL(blob);
a.download = filename;
a.click();
a.parentElement.remove(a);
