Yes - it's clear that WiringPi is not needed for I2C.

 

I added the PC2 board to ArmbianIO:

 

Good day!!!!! Forgive me for my bad english.
I really need your help. I have orangepi PC2.
For a very long time I have been searching the Internet for a working version of WiringPi or WiringOP, but unfortunately I can’t find a working version.
I tried many installation examples, but the result is not very pleasant. I also have Orangepi one, everything works well on this device. On the OrangePi PC2 device,
I just can’t overcome the problem of working with GPIO. When installing, Wiring PI or WiringOp constantly pops up errors. ((((Some examples work in half, 
there is no GPIO> PIN ..... I find it very difficult for you to properly explain what is wrong with the device. In other words, I can't use full

Some examples work in half, there is no GPIO> PIN ..... I find it very difficult for you to properly explain what is wrong with the device. In other words, I can't use full GPIO. In all versions one and the same error, I can not use all GPIO, some of them do not work at all.
At the command: sudo gpio readall the system shows me a table, in theory everything should work. and turn off the light bulb), and some do not even respond, and do not Appearing in / sys / bus / gpio / devices. Judging by the tests, I can only use wPi: 1,3,4,5,7,11. Some people write: undefined. Some simply do not respond. I could use much more on OrangePi One GPIO (PIN), such as (wPi): 21,22,23,24,25,3,7,1,4,5,11,27,28,29. (((((((((Very I ask to help me solve this problem. I’m new to this all, it’s very difficult to figure it out, but I don’t speak much English. I would be very grateful for any help in solving this problem.

added spoiler.. shorted quote - please add a spoiler nexttime yourself, thx

You can try other kind of libraries, such as https://github.com/duxingkei33/orangepi_PC_gpio_pyH3

Be aware that you will need to tweak this one to make it 64 bits compatible, since H5 is 64 bits, as explained here:
