as he said in comment for test write
code:
- gpio mode 0 up
- gpio mode 0 down
in other terminal , I did this and it just print waiting...
my question is , Is wiringPiISR working on orange pi one?
If the answer is yes, what should happen in this example?
Is it need any thing to connect to the pin Externally?
or can give me an other example for interrupt?
