problems with making generate code

tal333 · ‎2025-11-26

When I create a new GPIO port configured as OUTPUT in STM32CubeMX, the pin definitely exists on my board. However, after I click Generate Code, the new pin configuration does not appear in main.c (for example, I don’t see the initialization code for that pin in MX_GPIO_Init()).
Why does this happen? I tried to investigate but couldn't find the reason.
My STM32CubeIDE version is 1.19.0.
The MCU I am using is STM32G071RBT3, and the specific pin I am trying to add is GPIOD pin 3 — but I also don’t see any other newly added pins in the generated code. None of the new GPIO ports appear after code generation.

THANKS

Please include the IOC you're having trouble with. Probably you are not generating code or using the code that is generated.
