Hi, I've got a problem with my EXTI6. I try to get interrupt on falling and rising edges.
I've watched SFR register but I don't understand why it doesn't work.
PB IDR bit 6 always stay to 0 but I'm sure it's not true.
IRQ are enabled, software interrupt trig works perfectly.
I use Eclipse with Std peripheral lib V3.5.0.
Is anyone think about something ?
EDIT : Signal NOT moving when my program running.
Thanks.
