Is it possible to link same pin number of different GPIO ports on the same EXTI line ?
For example, create an interrupt on line_0 for the GPIO pin A0 and the pin B0. It seems impossible to achieve with the ST librairies - but I don't understand why it's impossible regarding to the internal schematic of the STM32F4... I really want to use more than 16 GPIO with interrupts. Is there a software way to perform this interruption ?
Thanks a lot !
