    That's incredible, I never imagined that was possible. The Apple ecosystem is very closed.I was checking if it exists for the iPod Classic since it's my favorite

    You're partially right. ESP32-C6 isn’t supported yet (only ESP32, S3, CAM, C3 for now), and the current flow is Arduino-based via arduino-cli — ESP-IDF support is planned a future …

    Yeah, definitely, ESPHome fits really well with what I’m building. I’m currently going through the docs to see how to integrate it properly

    Both, with a nuance. The AVR simulator syncs to wall-clock time and each frame calculates cycles from real elapsed deltaMs, so delay(1000) takes 1 real second and timer-dependent c…

    Yes,peripherals are fully emulated, not just the CPU. LEDs blink, buttons respond to clicks, Serial Monitor works, servos rotate, displays render (ILI9341 TFT), and we have 48 o mo…

    PIO isn't abstracted yet, we use rp2040js which has a full PIO emulator that executes the actual PIO instruction set (MOV, SET, PUSH, PULL, etc.) cycle by cycle, including the FIFO…

    Thanks! The rendering is DOM-based, circuit components are Web Components (from the wokwi-elements library) wrapped in React, and wires are SVG. No Canvas/WebGL, which keeps it sim…

    You can add peripherals There’s a “+” button on the right side of the circuit editor where you can add components like LEDs

    Thanks! Yeah, that’s probably the easiest way to get started, just load an example and hit “Compile + Play”. I tried to make it as close to zero-setup as possible so people can jus…

    Fair enough , though there’s quite a bit of low-level work behind it (emulation cores, QEMU integration, protocol timing, etc) Definitely inspired by existing tools, but trying to …

    That’s awesome — and exactly the kind of use case I had in mind Being able to iterate without constantly flashing hardware can save a lot of time early on. If you end up trying it …
