ESP32 Online systems Simulator you were looking for!✨ 2022✨

Wokwi ESP32 Simulator by Wokwi

You can use Wokwi to simulate the ESP32, and soon also the ESP32-S2. The Wokwi is a free online embedded systems simulator for electronics, and it runs in your browser.

This means you can simulate code that interacts with 3rd-party sensors, display modules, LEDs, and many other common parts. There's also initial support for WiFi simulation, and the developers are working on extending it to support connecting to any host on the internet (e.g. HTTPS/MQTT)

ESP32 Simulator is still in the preview phase but can already help you start with basics. More and more features will be added in the coming days. You can also be a part of the development 😀

Link on the ESP32 documentation - https://docs.wokwi.com/guides/esp32

You can use the ESP32 Embedded Systems Simulator in three ways:

• Build projects using the ESP32 Arduino Core
• Run MicroPython projects
• Simulate bin application files you built on your machine (e.g. using ESP-IDF)

Here are the three template links so that you can start right away!✨⭐

Simulator Examples #

Arduino Examples #

• Blink - In this example, you will Blink an LED connected to ESP32 pin D2
• Seven segment counter
• APA102 Color Cycles (TinyPico Board)
• WiFi Scanning

MicroPython Examples #

• SSD1306 Example
• NeoPixels
• WiFi Scanning

ESP-IDF Examples #

The following examples use the ESP-IDF functions. They are compiled using Arduino ESP32 Core:

• Blink using FreeRTOS API
• Binary LED counter using FreeRTOS tasks
• GPIO button input + interrupts
