[ SimulIDE Workspace ] +-------------------------------+ | [STM32F103] | | PA0 (ADC) <--- Potentiometer| | PA9 (TX) ---> Serial Term. | | PC13(GPIO)---> LED + Resor | +-------------------------------+ Adding the Components Locate the category in the left-hand component toolbar. Drag and drop the STM32F103 package onto the canvas. Add an LED and a Resistor (set resistor value to 220 Ohms).

Download the latest version from the official SimulIDE website . Extract the package and run the executable. Step 2: Prepare Your Code (STM32CubeIDE)

You can connect virtual LEDs, LCDs, and oscilloscopes directly to STM32 pins to watch the logic in action.

As of 2025-2026, the open-source community has made significant progress. Unofficial builds of SimulIDE integrate the backend or a custom ARM Cortex-M emulator.

Creating an STM32 circuit in SimulIDE follows an intuitive drag-and-drop workflow.
