WiringPI for NanoPI M1

Forum: Hardware
wertyzp 
Hi, please check my attempt to port WiringPI to NanoPI M1
https://github.com/wertyzp/WiringNP
I need someone to test GPIO IN/OUT functions and PWM
Please report any errors to github

I got warnings during first compile on my NanoPI NEO. See attachment.

All Done.

NOTE: To compile programs with wiringBP v2, you need to add:
    -lwiringPi
  to your compile line(s) To use the Gertboard, MaxDetect, etc.
  code (the devLib), you need to also add:
    -lwiringPiDev
  to your compile line(s).

I got the warnings as well.

Overall WiringPi works well with 14 of the 16 GPIO pins I tested. But it
does not work with WiringPi pins 2 and 3:

@wertyzp: Comments?

Hi!!!
Here are some examples for NanoPi 2 in Python.
http://www.friendlyarm.net/forum/topic/6810
http://www.friendlyarm.net/forum/topic/6811

Use library MAtrix
https://github.com/friendlyarm/matrix

HermannSW 
WiringPi library should be much faster since it does memory mapped GPIO
access while matrix library directly accesses/modifies
"/sys/class/gpio(..." files.

Hermann.

Check latest commit, fixed warnings and pins 2, 3

HermannSW 
Pins 2 and 3 work fine now, some warnings are left, see details here:

Hi, 

excellent work. All GPIOs are running on my NanoPi Neo. Thank you for the
lib. 
As I would do some programming with the NEO in python. Do you know a python
lib which will work with your WiringNP?

Regards

Peter
