1 wiringPi for Python简介
wiringPi for Python是wiringPi的Python语言扩展，用于在Python程序中操作GPIO/I2C/SPI库/UART/PWM等硬件资源，功能非常强大。
FriendlyELEC移植的wiringPi for Python现已支持FriendlyELEC-RK3399平台，目前支持NanoPi M4、NanoPi NEO4、和NanoPC-T4开发板。
当前提供的WiringPi版本：2.44

2 支持的OS
- FriendlyCore
- FriendlyDesktop
3 支持的开发板
- NanoPC T4
- NanoPi M4/M4v2/M4B
- NanoPi NEO4
4 wiringPi for Python在T4/M4/NEO4上的安装
通过ssh，或者串口终端进入开发板的命令行，然后根据你所用的Python版本，在命令行下安装:
4.1 Python3安装方法
apt install git python-dev python-setuptools python3-dev python3-setuptools swig wget https://pypi.io/packages/source/s/setuptools/setuptools-33.1.1.zip unzip setuptools-33.1.1.zip cd setuptools-33.1.1 python3 setup.py install wget http://112.124.9.243/wiringpi/rk3399/wiringpi-2.44.4-py3.6-linux-aarch64.egg easy_install wiringpi-2.44.4-py3.6-linux-aarch64.egg
4.2 Python2安装方法
wget https://pypi.io/packages/source/s/setuptools/setuptools-33.1.1.zip unzip setuptools-33.1.1.zip cd setuptools-33.1.1 python2 setup.py install wget http://112.124.9.243/wiringpi/rk3399/wiringpi-2.44.4-py2.7-linux-aarch64.egg easy_install-2.7 wiringpi-2.44.4-py2.7-linux-aarch64.egg
5 wiringPi for Python示例
将一个Matrix - LED通过连接至开发板，引脚的连接对应如下：
| Matrix-LED | T4/M4/NEO4开发板 |
| S | Pin7 |
| V | Pin4 |
| G | Pin6 |
接下来我们用wiringPi实现一个LED闪烁的例子,
在代码中使用数字7来操作Pin7这个引脚:
5.1 Python语言示例
创建一个python源文件：
vi led.py然后键入如下代码:
import wiringpi as wpi import time wpi.wiringPiSetup() wpi.pinMode(7, 1) while True: wpi.digitalWrite(7, 1) time.sleep(1) wpi.digitalWrite(7, 0) time.sleep(1)
运行：
python3 led.py
看到LED灯一闪一闪的，就表示成功了，如果你使用的是python2，请将python3改成python2。
