I tried to search for any previous implementation of the EXTI interrupt
controller for the PC10 pin. The only thing I found is that the pin for
PC10 is prepared for working as input
(link<https://github.com/Ell-i/Arduino/blob/ell-i/hardware/ell-i/stm32/variants/ellduino_stm32f051/stm32f051_init.c#L365>)
on the working Runtime implementation for the Arduino repository.
Is there any implemented / example code where the EXTI peripheral module is
configured and activated? If not, to start considering generating one right
away for the new CoAP branch of the Runtime, and meanwhile configuring the
peripheral after the main initialization.
BR, Ivan
