I am working with a Nucleo-F411RE and I would like to implement 6 external interrupts using Port B.
I am a bit confused about how GPIO can be selected to use for external interrupts. According to post #2 I could use multiple pins from Port B but can’t be continuous. For example: PB_1, PB_3, PB_5, PB_7, PB_9, PB_11… Am I correct?
Or is it possible to select them continuously (PB_1, PB_ 2, PB_3, PB_4, PB_5, PB_6).
My purpose is to keep an schematic design as clean as possible but I understand that I need to adapt my wiring diagram according to the MCU architecture and pinout. So any help will be great!
If this is not the case, is there a way to understand better how to select the interrupt pins ?
