1 Introduction to WiringPi for Python

The wiringPi for Python utility is an implementation of wiringPi in Python. It can be used in Python programs to access hardware such as GPIO/I2C/SPI/UART/PWM etc. It is a popular and powerful utility.
FriendlyELEC has ported the wiringPi for Python utility for all existing FriendlyELEC-RK3399 based boards: NanoPi M4, NanoPi NEO4 and NanoPC-T4.

Current version: 2.44
WiringPi's home page: http://wiringpi.com

There is a C version too and here is the reference link: WiringPi for RK3399

2 Supported OS

  • FriendlyCore
  • FriendlyDesktop

3 Supported Boards

  • NanoPC T4
  • NanoPi M4/M4v2/M4B
  • NanoPi NEO4

4 Install WiringPi for Python on T4/M4/NEO4

Log in a board(T4/M4/NEO4) via SSH and run the following commands:

4.1 Install WiringPi in Python3

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 Install WiringPi in Python2

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 Code Samples Using wiringPi for Python

Connect a Matrix - LED module to your board and make sure the hardware setting is as follows:

Matrix-LED T4/M4/NEO4
S Pin7
V Pin4
G Pin6

Here is a code sample showing how to make an LED blink using wiringPi,
In the code sample '7' stands for 'Pin7':

5.1 Code Sample in Python

Create a source file in Python: 

vi led.py

Type the following lines: 

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)

Run: 

python3 led.py

If everything is correct you will observe that the LED blinks. Note: if you use Python2 instead of Python3 make changes in the above commands accordingly.

5.2 Code Sample in C
