How does Wokwi work?
Wokwi compiles your code into a binary firmware, and then executes the binary firmware one instruction at a time, as a real microcontroller would. If you want to learn about the internals, check out the following resources:
- Raspberry Pi Pico and RP2040 Deep Dive - This 5 hours course will give you good understanding of the RP2040 architecture, and how it works.
- Live-coding Raspberry Pi Pico Simulator from Scratch - 70 hours long live-coding series where you'll see how we built the Pi Pico simulator, along with explanations about the architecture and design decisions.
- AVR8js: Simulate Arduino in JavaScript - Blog post covering the basics of the Arduino simulation engine.
- Let's Code Arduino Simulator from Scratch - Create a simple Arduino simulator app using Wokwi's AVR8js open-source AVR simulation engine (16 minutes).
