Hi, all I'm working with NUCLEO BOARD F401RE developing with Mbed online IDE

I've noticed that if I set two or more of this pins

PC_10, PC_11, PC_12, PC_13, PB_12

as InterruptIn, when one of this fire make the code blocking until I reset all the board

Do you know something about?

Let me know.

Are you using the latest mbed library? (Right mouse button, click update). There have been improvements to some nucleo targets, including I think the F401, to increase number of pins being capable of InterruptIn simultaniously.

However there is a hardware limitation that it is not possible to have different pins with the same number both as InterruptIn (well it is technically possibly, but you never know which one caused the interrupt). So both PC_12 and PB_12 as InterruptIn is not possible.
