avr8js VS ObsiDOOM

Wokwi is free open source and neat with an MIT license https://github.com/wokwi/avr8js https://wokwi.com

What I really want is a modern microcontroller emulator. avr8js is really spectacular. Execute Code provides a great way to run C, C++, and Rust snippets, but running a program on an OS versus on an MCU is very different and code is generally not very portable between them.

We simulate the actual Arduino hardware (based on this avr8js repo) which runs the compiled Arduino code. To compile the code itself, we use Arduino CLI.

Here Uri is tackling a subtle but impactful bug in the AVR simulator. He starts by analyzing a tiny Arduino program that shows the problem: an LED turns off when it shouldn't. Then we dive into the assembly code, and take a look at the implementation of the offending instructions in the simulator's source code. Once we pinned down the bug (pun intended), we create a regression test case and change the simulator's code until the tests are all green again. Enjoy the ride! ▸ GitHub issue with the all details: https://github.com/wokwi/avr8js/issue... ▸ Wokwi online Arduino simulator: https://wokwi.com

I hope you have heard about the Wokwi Arduino Simulator. There is an engine thatthat is open source. You can hop on the discord channel and get more help/support from the community over there. there are a lot of welcoming active people helping out each other.

This is a completely free Arduino simulator based on the AVR8js engine (open-source on GitHub)/

I don't know whether you saw it, but /u/wokwi has actually done a similar thing with https://github.com/wokwi/avr8js in a totally different way - no WASM, an AVR implementation in JavaScript. Total madness but it works!

At the moment you can't. But you can read the instructions on this GitHub page and tell me which game you want to play, then I can add it in the next update.
