this is my first topic on the forum, so please me in advance if I make some mistake.
As the subject suggests I have some trouble with the interrupts. In my project, I use a Nano 33 Ble board with several buttons (around 10) and I'd like to manage the buttons' states exploiting interrupts.
If I define a specific interrupt for each button everything goes right up to the first 8 interrupts. The 9th interrupt seems to not be triggered.
Is there a maximum number of attachable interrupts?
