This article explores the concept of —how to set it up, what works, what doesn’t, and how to simulate complex STM32 projects with peripherals like GPIO, timers, USART, and even SPI/I2C. What is SimulIDE? A Quick Refresher SimulIDE is a real-time electronic circuit simulator. Unlike text-based simulators, it provides a graphical interface where you drag and drop components (LEDs, resistors, oscilloscopes, microcontrollers) and wire them together. It then executes your compiled firmware (HEX or ELF file) on a virtual microcontroller.
Enter . While SimulIDE has historically been known for simulating AVR chips (like Arduino) and basic 555 timers, the landscape has changed dramatically. Developers have been asking: Can I run a full STM32 simulation?
Download a community build today. Write a simple blink program. Connect a virtual button and LCD. You will be shocked at how close it feels to real hardware. And when you finally upload that same code to a real Blue Pill, it will work on the first try.
For production firmware (timing-critical, DMA, USB), – you still need real hardware and an oscilloscope.
HAL_GPIO_TogglePin(GPIOC, GPIO_PIN_13); HAL_Delay(500);
