What are mbed files that contain pin external interrupt config? (only PB_3,4,5,PC_13 work for me)

You can use external interrupt on all pins. The MCU has 16 EXTI channels and it can handle one pin on one channel. So if you set PA_0 as interrupt in, you can not set PB_0, because these are on the same channel (0). https://stackoverflow.com/questions/36438879/multiple-interrupts-on-the-same-exti-line-stm32
Thank you Mark, I've tried that before e.g. PH_0 alone then PH_1 etc, did not work for me except for those pins mentioned in my question.
