This simulation runs at near real-time speed on a modern PC. You can change the potentiometer value with your mouse and instantly see the LCD update, the UART print, and the servo move. That is the power of SimulIDE STM32 Full.

In Your Code (main.c):
HAL_Init(); SystemClock_Config(); MX_GPIO_Init();
while (1) HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_5); HAL_Delay(500);
Compile for Simulation:
make all
# Output: firmware.elf
Load into SimulIDE:
If done correctly, the virtual LED will blink. This is the foundation of the SimulIDE STM32 Full experience.
In the world of embedded systems development, the STM32 series by STMicroelectronics has become the gold standard for 32-bit ARM Cortex-M microcontrollers. However, developing firmware for STM32 often involves expensive debugging hardware, breakout boards, and a tangled mess of wires. What if you could write, test, and debug your STM32 code entirely on a computer before touching a single physical component?
Enter SimulIDE. 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?
This article explores the concept of SimulIDE STM32 Full—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. simulide stm32 full
#include "main.h" #include "gpio.h"int main(void) HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); // Sets up PC13 as output (on Blue Pill)
while (1) HAL_GPIO_TogglePin(GPIOC, GPIO_PIN_13); HAL_Delay(500);
Compile this to blink.hex.
Once you have basic GPIO working, explore the "full" capabilities: This simulation runs at near real-time speed on a modern PC
For learning STM32, prototyping algorithms, or testing hardware-dependent logic without soldering, yes – SimulIDE STM32 Full is a game-changer. You can iterate 10x faster than programming physical boards.
For production firmware (timing-critical, DMA, USB), no – you still need real hardware and an oscilloscope.
Final recommendation: 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.
SimulIDE STM32 Full is not just a simulator – it is a bridge between imagination and embedded reality.
