This is a modified WiringPi for OrangePi. We call it WiringOP. Test fo Orangepi pc
2016.07.27 - trustfarm has configured kernel embedded module i2c,spi to default So, No needs to check the moduleLoaded. in this code ignore it and go.
git clone https://github.com/trustfarm/WiringOP.git
cd WiringOP
chmod +x ./build
sudo ./build
orangepi@orangepi:~$ gpio readall
