Arduino for STM32

ok, many thanks for your help ! Fortunately I only have 15 interruptions

really ? I was thinking it will only act with priority.

Hello, Thanks for your feedback. My project is really big and I can not share it easily. I do not used interruption in parallel, the conflict happens using pins one by one. Some pins does not react anymore, but depending of order of attachinterrupt instructions. I've disabled some hardware pins in s...

Hello, I've developped a board based on stm32f103RB6T and maple libraries. I'm using 15 external interruptions pins. It seems I have a conflict between interruptions, some of them are not detected. If I change order of attachInterrupt instructions, other pins become unavailable, so the order changes...

Hello,
