Yeah, it is, port 22 and port 23 don't work, I tried port 0 and port 1, it works.

I think the problem is the original ultrasonic distance sensor that roli comes whit is broken. Because I believe I must tested it before when I first got roli, and it didn't wokr. Also, I test it in my arduino, it doesn't work neither.

Anyway, I finally figure it out, thank you for your help.
