I'm stupid !
Now: typing the follow cmdprocinfo |grep keyboard
then: touching "UP" key && "Enter" key
next: redo it 2-3 times
Here is the question:
How many times are there when using keyboard?
When a A-Z pressing,there is 2 times!! But when you press other key...
?!WHY!? confusing, u mean # of intr? Oh,sorry.
I mean how many interrupts there are when you press one key? And why? Help Me!! looks like two.
maybe one when u press down and one when u release? i guess. u can check doc on keyboard
