Integrate Kaluma + support JS files

[drohen]

Wokwi doesn't have a JS runtime for RP2040, and also the code editor doesn't support JS files. Implement loading Kaluma-based projects along with allowing JS files and maybe auto-complete for the Kaluma/JerryScript API.

some implementation notes:

Kaluma Flash Layout. The code is stored separately from the rest of the file system (there's 512kb for code storage, 512kb for the filesystem). It is stored as a simple null-terminated string.

Well, I managed to hack something together so hopefully it'll be useful enough for your talk:

Ok, so it works - which is so great! I'll keep appending to this issue any bugs I find.

For some reason it does a soft reboot immediately after loading, so I can get a single value out, but then I need to enter: .load code.js in the REPL to get it running again.

What if you add a delay(1000); at the end of the code?

[drohen]

I'll try, btw this is a basic example: https://wokwi.com/arduino/projects/320701865454994003

delay doesn't help

Weird though that it needs a loop, but on the board and running it with .load code.js doesn't seem to. Is this something that's likely to do with Wokwi or Kaluma?

[urish]

That's a good question!

[drohen]

I can work with what there is for now anyway, I don't see anything wrong with having a loop with the delay call. If you find it's something to do with Kaluma, I'm sure the dev would be interested. Cheers

Seems like it was Wokwi. Try your original example again?

[drohen]

Yep works as expected!
