3.15. How to install wiringOP

Note that wiringOP has been pre-installed in the Linux image released by

Orange Pi. Unless the code of wiringOP is updated, there is no need to re-download,

compile and install, and use it directly.

The storage path of the compiled wiringOP deb package in orangepi-build is:

orangepi-build/external/cache/debs/arm64/wiringpi_x.xx.deb

After entering the system, you can run the gpio readall command. If you can see

the following output, it means that wiringOP has been pre-installed and can be used

normally.
