树莓派3安装新版wiringpi-python避免错误提示Unable to determine hardware version

新版树莓派3的系统可能不再兼容wiringpi-python，运行会提示：

Unable to determine hardware version. I see: Hardware  : BCM2835

- expecting BCM2708 or BCM2709.

If this is a genuine Raspberry Pi then please report this

to [email protected]. If this is not a Raspberry Pi then you

are on your own as wiringPi is designed to support the

Raspberry Pi ONLY.

这是因为wiringpi-python库还没更新导致的，因此需要手动安装wiringpi-python，感谢neuralpi为我们提供修改版的wiringpi-python

安装之前，需要先安装swig2.0和python-dev

sudo apt-get install swig2.0 python-dev

接下来安装wiringpi-python：

git clone --recursive https://github.com/neuralpi/WiringPi-Python.git

cd WiringPi-Python/WiringPi

sudo ./build

cd ..

swig2.0 -python wiringpi.i

sudo python setup.py install

sudo python3 setup.py install
