STM32CubeIDE vs Wokwi

STM32CubeIDE is a C/C++ environment for editing, compiling, and debugging code for STM32 devices. ST offers an Eclipse-based IDE and a Visual Studio Code variant, and identifies the VS Code version as its primary IDE focus. The Eclipse version supports all STM32 microcontrollers and microprocessors; the VS Code version supports all STM32 microcontrollers. Both are listed for 64-bit Windows, Linux, and macOS.

The IDE includes a C/C++ editor and supports GCC and Clang toolchains. Debugging features include breakpoints, CPU core registers, memory and live-data views, SFR registers, RTOS debugging, and fault analysis. Supported probes include ST-LINK and SEGGER J-Link. ST says the IDE is commonly used with STM32CubeMX and is compatible with TouchGFX Designer, STM32Cube AI Studio, and motor control workbench. The VS Code variant uses CMake and Ninja. Telemetry is optional and can be disabled in Visual Studio Code settings. It is free to download and use, though the ST application is proprietary.

Wokwi is a simulator for building and debugging firmware for simulated microcontrollers. It supports Arduino (C/C++), MicroPython, CircuitPython and Rust, with boards including Arduino Uno, Nano and Mega, ATtiny85, ESP32-family boards, several STM32 models and Raspberry Pi Pico. Supported protocols include WiFi, HTTP, HTTPS, WebSocket, MQTT, NTP, CoAP, DNS, TCP, UDP, UART, I2C and SPI. The simulated targets are AVR, ESP32, STM32 and RP2040 microcontrollers; firmware can also be exported for Raspberry Pi Pico. Wokwi lists web, Linux, macOS and Windows platforms. Its free Community plan includes unlimited simulations, unlimited public projects and Virtual WiFi. Paid plans are billed annually: Hobby is €5.60 per month with 100 fast build minutes monthly; Hobby+ is €8.10 per month with 500; and Wokwi Pro is €20.00 per month with 1,000 fast build minutes and 2,000 CI minutes monthly.
