The default installation paths (Proteus 8.x):

C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY

For Portable/Windows Store versions, check: C:\Users\[YourUserName]\AppData\Local\Proteus 8 Professional\ proteus library for stm32 install

If you prefer a simpler approach, you can simulate STM32 programmed via Arduino Core: The default installation paths (Proteus 8

Limitation: Some Arduino libraries (Wire, SPI) may not simulate perfectly. Limitation: Some Arduino libraries (Wire, SPI) may not

If you are new to STM32, you are likely better off using a simulation model that treats the STM32 like an Arduino.

  • Pros:
  • Cons:

    • If you have a different STM32 variant:

    Let’s run the classic “Hello World” of embedded to confirm everything works.
