Simulate Arduino, ESP32, Pi Pico, STM32, And ATtiny with Wokwi

5 місяців тому

When I listened to The Amp Hour, episode #599, I was astonished by the project and its creator, Uri. He built a simulator for all kinds of MCUs and electronic parts. This project is so cutting-edge that I cannot believe only one young guy was able to create it. And because it is useful and fun, I invite you to follow me.

Excellent! Just what the Arduino/ESP32/STM/Pico world needs! Truly amazing implementation...

I would rather see implementation with symbols of the components (like most simulators) instead of pictures of components.

Another great video! Wokwi is simply amazing and it deserves a wider audience. I've been using it for some time now and it can be quite useful. It even allows you to use all libraries that are available in the Arduino library manager. It was quite interesting to successfully test a virtual TM1637 display with my TM16xx library. I also tested the serial output for an I2C scanner and must say it's astonishing to see how accurate the simulation is. Of course not everything is identical (e.g. timing), but al in all Wokwi is a very useful product and a wonderful achievement.

I agree. This is why I thought it deserves a video…

With my students we use simulIDE as it can be set locally quite easily on mac/windows/linux but yes Wokwi is pretty nice too. With SimulIDE we also are able to use the real serial port of the PCs we use so the student can interface their virtual arduino/esp32 with actual devices plugged.

Wow! Exactly what I was looking for! A real desktop application running on Mac and Windows! What makes it unique is its ability to create and simulate high level components, such as MCUs, as well as lower level discrete components. I don't like how the developer of WOKWI incorporates free and open source software created by others and serves it behind a paywall for profit. While it maybe perfectly legal, it's far from the spirit of open source whose contributors intended their code to benefit the community and not for the financial benefit of an individual.

@bobweiram6321 Could you please add the evidence for your allegation?

@bobweiram6321 5 місяців тому

@@AndreasSpiess Where do I begin? It's painfully obvious. The libraries and compilers used for simulator are all open sourced. It uses MicroPython, Arduino, and Rust compiler and libraries. It even "uses" its RP2040 Ada PIO code generator from an open source Ada project. Even the editor, icons, JavaScript libraries as well as the HTML framework used to build the site are open sourced too. It's not a matter of what's been borrowed from open source projects, but what's not been borrowed from other open source projects. WOKWI's main app, however, which integrated the other open source packages is closed source. They do have a repo on GitHub, but it only for ancillary projects such as examples and some of the packages used in building the app. I would post a link, but I don't want this comment flagged. WOKWI gets away with this because it circumvents open source license requirements via legal loopholes, making it technically legal, but highly unethical. Open source licenses were written before the advent of cloud computing. Since cloudware is not distributed as copies, it's under no obligation to the terms of the open source projects used. Moreover, WOKWI doesn't give any form of attribution to the open source projects it's derived from, which makes it even more scummy. You yourself was mislead into thinking Urish wrote the entire application by himself. I'm shocked other people haven't called Urish out on it. In fact, he's been given a platform on several community venues to give demonstrations and tutorials. In reality, these are merely underhanded sales and marketing opportunities to sell WOKWI.
