I need to compile generated source code in js runtime then upload it to my device.

Compiling:

I have found arduino-cli

Uploading:

There is only avrgirl but it doesn't work in browser. What should I do?

  • Arduinos cannot be programmend in Nodejs. You need to write C/C++ or Assembler.

  • @chrisl, it's not about programming (code is c-generated one) it's about calling compiler from js

    Ah, ok. But you can also upload sketches with arduino-cli. If you can use it, you can also upload sketches

You can't, and that's a good thing. If the browser could let a Web site access your hardware, that would be a huge security breach. You may be able to bypass this security restriction if you can write an extension (plugin) for your browser.

  • Okay then I will use extension for hex code uploading. Then how can I compile it using only in-browser js?

  • I mean: source code -> String -> Compiler -> Hex-string -> Extension -> Uploading

  • @caxapexac: Building a C++ compiler in JavaScript is not a trivial task. You may try to port avr-g++ using Emscripten. Dec 8, 2019 at 17:42
  • Seems for me a weird way to do everything in the browser. Normally in such a situation you are actually building a web service, so the compilation could be done server side by calling avr-g++ or arduino-cli through the nodejs code. Then you only would need to encapsule arduino-cli in an extention for uploading on the local computer

  • I modify the code from js-stk500 to work from browser with web serial API. but I can't makr Arduino CLI to work in browser. Is that possible?
