WiringNP in QT

Installing WiringNP

The WiringNP in the /root folder, at least for NanoPI K1 Plus, is not good. It shows the NanoPI Neo/Neo2 GPIOs.

Reinstall it from sources:

git clone https://github.com/friendlyarm/WiringNP
cd WiringNP/
chmod 755 build
./build

then, check it via gpio command

gpio readall

Use in QT

Add the following line to <project>.pro:

LIBS += /usr/local/lib/libwiringPi.so

It will include the libpthread.so library automatically.

In the files, don't forget to add

#include <wiringPi.h>

and

wiringPiSetup();
