WiringPi

OrangePi官方的WiringPi,看着写着支持全系列板子，具体不清楚，只在2G-IOT测试过。在我的Raspbian 2G-IOT上。

下载:

env GIT_SSL_NO_VERIFY=true
git clone https://github.com/OrangePiLibra/WiringPi.git

安装编译依赖：

i 安装源码需要的编译工具
sudo apt-get install gcc g++ make

编译安装WiringPi:

cd WiringPi
sudo ./build OrangePi_2G-IOT
sudo ./build OrangePi_2G-IOT install

尝试样例：

  cd WiringPi/example/OrangePi
  make OrangePi
  ./OrangePi

查看GPIO信息：

gpio readall

   orangepi@orangepi:~$ gpio readall
