arduino-web-uploader

Upload compiled hex files to your boards directly from a webpage. (Chrome only)

Try it now without having to install anything at https://dbuezas.github.io/arduino-web-uploader/ (Chrome only, any pc OS. Android, not yet)

Currently supports these boards:

• lgt8f328p (see https://github.com/dbuezas/lgt8fx)
• uno
• nano
• nano with old bootloader (most chinese clones)
• pro mini

The Web Serial API is available on all desktop platforms (Chrome OS, Linux, macOS, and Windows) in Chrome 89.

Import directly into HTML

Just add the following to the head of your HTML:

<script src="https://github.com/dbuezas/arduino-web-uploader/releases/download/v1.0.0/main.js"></script>

And add some buttons with their corresponding attributes

<button arduino-uploader hex-href="[path to your hex file]" board="[name of the board]" verify [optional]>
  Upload blinker to lgt8f328p and verify uploaded code
  <span class="upload-progress"></span>
</button>

Where:

[arduino-uploader]

indicates to the library that it should attach the functionality to this button

[hex-href]

is the url of the hex file to upload. Let me know in the issues if you have a use case to let the user select a hex file from their own computer.

[board]

can be any of these:

• "lgt8f328p"
• "nanoOldBootloader"
• "nano"
• "uno"
• "proMini"

(here are the definitions: https://github.com/dbuezas/arduino-web-uploader/blob/master/src/index.ts#L13-L44. You can see that nano, uno and proMini have the same parameters.)

[verify]

Is optional, so you can chose to leave that attribute out or write it there. In my experience, uploads never get corrupted and removing verification makes it twice as fast.

<span class="upload-progress"></span>

Is a placeholder element where progress percentage will be shown

for example:

<button arduino-uploader hex-href="./blinker.nano.hex" board="pro-mini">
  Upload blinker to pro-mini and don't verify (faster)
  <span class="upload-progress"></span>
</button>

see more examples in https://github.com/dbuezas/arduino-web-uploader/blob/master/index.html

Generating hex files

use the hex WITHOUT the bootloader.

Using as a node module

installation

npm install arduino-web-uploader or yarn add arduino-web-uploader

usage:

import { upload, boards } from 'arduino-web-uploader'
document.addEventListener('button', async () => {
  const onProgress = (percentage) => {
    console.log(percentage + '%')
  }
  const verify = false
  console.log('starting')
  await upload(boards.nanoOldBootloader, 'http://your-site.com/hex-file.hex', onProgress, verify)
  console.log('done!')
})

also check the code of the stand alone html plugin: https://github.com/dbuezas/arduino-web-uploader/blob/master/src/test.ts

Structure

• dist/: typescript transpiled to javascript files for npm
• src/index.ts: uploader code
• src/Serial.ts: a wrapper of navigator.serial which also emulates a node stream for compatibility
• src/test.ts: a wrapper of the lib to use in HTML without writing javascript (for lazy people like https://github.com/seisfeld :D)
• test/*: some test html file. The file src/test.ts is also bundled there by webpack
