Ensure that your external compiler is explicitly targeting the exact ARM architecture variant of the MCU dropped onto the canvas.
Watch registers change, pins flip states, and voltages shift in real time.
SimulIDE is a Qt-based, cross-platform software that allows users to design, simulate, and program microcontrollers in a virtual environment. The software supports a wide range of MCUs, including the STM32 family. SimulIDE's core features include: simulide stm32 full
Once SimuLide is open, navigating to the STM32 chip is straightforward: Look at the left-hand . Expand the Components category, then open MCU . Expand the ARM or STM32 subfolder.
Find the section and select your target variant (e.g., STM32F103 ). Ensure that your external compiler is explicitly targeting
Download the latest version of SimulIDE from the official website. Extract the zip file and run the simulide.exe . 2. Prepare the Toolchain
When you open SimulIDE, you won't find an "STM32" folder exactly like the AVR or PIC ones. Look for a specific component labeled or a generic ARM-based MCU placeholder. Depending on the version, you might need to select a specific STM32 model supported by the QEMU backend. The software supports a wide range of MCUs,
Connect a component to pin PA0 . Program the STM32 ADC register to read continuous voltage fluctuations and monitor the variable register value inside SimulIDE. UART Communication
Use the UART component to send data from the STM32 to a Serial Monitor.
Connect virtual probes or oscilloscopes to the pins to visualize signals like PWM or serial data. Relevant Resources Official Tutorials: SimulIDE Blog
