Raspberry Pi Pico W (RP2040 + Wi-Fi)

Raspberry Pi Pico W: RP2040 as on the Pico plus the CYW43439 Wi-Fi chip (2.4 GHz, internally on GP23/24/25/29). Arduino sketches with WiFi, WebServer, HTTPClient, MQTT (PubSubClient) run with the firmware's real TCP/IP stack (lwIP); the Wi-Fi chip is modeled at its interface and connects to the simulation's virtual network (router with DHCP/DNS, MQTT broker, test server, "Network" panel). The onboard LED is on the Wi-Fi chip (LED_BUILTIN).

Notes

The firmware runs on an emulated CPU core, instruction by instruction. Peripherals that the model implements (GPIO, timers, UART, SPI, I²C, ADC and others, see the description) act on the pins of the circuit, so the analog parts around the chip see the same voltages and timing as on a real board.

The Wi-Fi chip connects to the virtual network of the simulation: add a "Wi-Fi router" part and watch the traffic in the Network panel.

  • Right-click the part and choose "Open in code editor" to write and compile its code; "Serial monitor" shows its UART output.
  • In the inspector you can load a demo firmware or your own ELF / Intel HEX / BIN file instead.
  • GPIO pins are real circuit pins: an LED on an output needs a series resistor, an input needs a defined level (pull-up or pull-down).
  • The debugger in the code view stops at breakpoints and shows registers, variables and the call stack.

Simulation model

An emulated CPU core runs the firmware binary instruction by instruction. The GPIO pins are pins of the analog circuit: outputs drive through a driver resistance, inputs read the voltage with thresholds.
