Hi HN,

I’ve been working on esp32sim, an open-source ESP32 emulator that runs in the browser.

The fun part of the demo is that there is no ESP32 involved — the firmware is executing in the emulator.

The goal is to make ESP32 software easier to experiment with, test and simulate without always needing physical hardware connected.

I made a short video showing it in action: https://youtu.be/waoWFilTWEc

I’m particularly interested in feedback from embedded developers: what would an emulator like this need to support before you’d actually use it for development, testing or CI?

How is this different from Wokwi.com? They’ve been doing for years, and have a large number of microcontrollers emulated.
