Stm32F072CBT6 versus Stm32F072C8T6

[JamesMoriarty]

hello. I was using PA9 pin as an interrupt in a project made with Stm32F072CBT6. I am working as Stm32F072CBTx in cubeide. The card I am working on accidentally installed Stm32F072C8T6. only difference is that it is visible in flash but PA9 pin can be defined as interrupt in the same way but the function does not work. Is the fact that the processors are different a reason why the interrupt cannot work?. I do not get any overflow error caused by flash.

Hello

Stm32F072CBT6 : 128kB of flash

Stm32F072C8T6:  64kB of flash

The only difference is the flash size. I don't think the problem you are facing has relation with this difference.

Maybe you need to share your two ioc files for both devices so we can help you efficiently.
