Hello.
My colleague is in trouble about NVIC of STM32L053..
At the moment, he wants to use several external interrupts;
some of them are assigned to EXTI line 0, some others are assigned to EXTI line 1,
and the rest are assigned to EXTI line2.
According to him, EXTI line 0 doesn't work at all regardless edge trigger happens.
Also some interrupts of line 1 and line 2 don't work at all regardless edge triggger happnes as well.
Does he take care of setting register when he assigns several interrupt to the same vector ? If someone can offer a sample program to solve this issue, I appreciate it.

Regards
