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 M4NanoPi NEO4、和NanoPC-T4开发板。

当前提供的WiringPi版本:2.44
WiringPi项目主页: http://wiringpi.com

wiringPi的C语言版本,请前往这里查看: WiringPi for RK3399/zh

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。
