Hi leonzhangzhang,
here you can see all gpio that are usable by wiringPi:

Code:

All the pins that are IN or OUT can be used.
Note that the pins 32 and 33 normally also are usable, but I changed the devicetree to have the ttyS4 there.
Best is you check on your own system with gpio readall.

Hi, lobo
How did you connect the I2C mode? (27 and 28 PIN).
I see only up to 26 pins

Help me please.
