This is a fork of the RPi.GPIO_NP from friendlyArm.com (https://github.com/friendlyarm/RPi.GPIO_NP). (The orignial of their README.md is reproduced below.) Changes have been made to 4 of the "C" code modules to allow it to work with armbian fusion. Additionally, errors were corrected in the event_gpio.c module to fix failing function calls due to undersized char arrarys leading to truncation of filenames. Follow the Installation instructions from the original READ.me to compile and install. Additionally errors in compilation have been fixed by multiple definitions of variables.

Changed modules are:

boardtype_friendlyelec.c
boardtype_friendlyelec.h
c_gpio.c
py_gpio.c
event_gpio.c common.c
Python 3.9 usage

(Note that these revisions have only been tested with a NanoPi NEO.)

----- Original READ.me from https://github.com/friendlyarm/RPi.GPIO_NP -----

This is a modified version RPi.GPIO for NanoPi NEO/NEO2. We call it RPi.GPIO_NP. It is based on the original RPi.GPIO. The RPi.GPIO_NP API usage are the same to the original RPi.GPIO. You can donwload the RPi.GPIO_NP from: https://github.com/friendlyarm/RPi.GPIO_NP

Currently supported boards (Allwinner H3/H5)

NanoPi Neo
NanoPi Neo Air
NanoPi Duo
NanoPi Duo2
NanoPi NEO2
NanoPi NEO Plus2
NanoPi M1
NanoPi M1 Plus
NanoPi NEO Core
NanoPi NEO Core2
NanoPi K1 Plus

Installation

Log into your nano board via SSH, open a terminal and install the WiringNP library by running the following commands:

sudo apt-get update
sudo apt-get install python-dev
git clone https://github.com/friendlyarm/RPi.GPIO_NP
cd RPi.GPIO_NP
python setup.py install                 
sudo python setup.py install

Please be attention that you need use both python and sudo python to make the RPi.GPIO_NP work well.

Code Sample

connect a LED module to a NanoPi (Pin7), Create a source file in Python:

vi led.py

Type the following lines:

#!/usr/bin/env python
import RPi.GPIO as GPIO
import time
PIN_NUM = 7
 
GPIO.setmode(GPIO.BOARD)
GPIO.setup(PIN_NUM,GPIO.OUT)
while True:
        GPIO.output(PIN_NUM,True)
        time.sleep(1)
        GPIO.output(PIN_NUM,False)
        time.sleep(1)

Run led.py:

chmod +x led.py
sudo ./led.py

You can see the LED is blinking.
