I want to use the lcd example. But i see that the pins are still defined for the raspberry PI, i don't know the mapping, and how i cloud define them. And besides the example, how could i than define the pins.

It's works right in RPi.
Pulse width is 1.5ms

gpio mode 1 pwm
gpio pwm-ms
gpio pwmc 1920
gpio pwmr 200 # 0.1 ms per unit
gpio pwm 1 15 # 1.5 ms

It's don't works right in NPi.
A pulse width isn't probably right.
gpio mode 33 pwm
gpio pwm-ms
gpio pwmc 1920
gpio pwmr 200 # 0.1 ms per unit
gpio pwm 33 15 # 1.5 ms

I have a NanoPi A64 based on the Allwinner A64 chip

How can I add support for it in this library ?

I've forked and friendlyarms fork of this repo.
when running gpio readall I get the 'bold' output.
when changing the pin to output and high and low the gpio readall doesn't change (neither direction nor pin nor level) "24 | 0 | IN | GPIOL11 | 18 | -1 |"

I created an SD card with a fresh copy of "nanopi-neo2_friendlycore-xenial_4.14.52_20180628.img"

logged on as root via ssh

after the first boot I disabled UART2 with npi-config

then I installed wiringnp like this:

git clone https://github.com/friendlyarm/WiringNP
cd WiringNP/
chmod 755 build
./build

when I use: gpio mode 0 out the gpio is set to out
but when I do gpio write 0 1 the gpio is not set to high
this can been seen with the gpio readall command

If I do the same with GPIO 2 it works perfectly well.

Is this a bug or am I overlooking something?

Hello,
is it possible to add this library to the aforementioned service?

I have a NanoPi Neo and I think it's a good thing to be able to update the module directly from pypi with a simple command.

Cheers

gpio says.. on NEO2.....root@neo2:~/WiringNP# gpio readall
piBoardRev: Unable to determine board revision from /proc/cpuinfo
-> Is not H3 based board
-> You may want to check:
-> http://www.lemaker.org/

Hello, I would like to know if there is any kind of implementation for the WiringNP library for the NanoPC T2 board, If not, I would like to know what types of changes I have to make in the mapping to make this work.
I would also like to know the performance of the library in Khz or Mhz. (The basic test setup was toggle one of the GPIO pins between zero and one as fast as possible)
Best Regards

Hi,
i'm able to manage GPIO pins by /sys/class/gpio in sys mode (export/unexport), to turn on a led for example, but i'm not able to manage a DHT11 or ultrasonic sensor, because it's not possible to "pullUpDnControl" on sys mode (wiringPiSetupSys)
What about nano pi 2 fire support on WiringNP?
That would solve my problem...
Let us know

It's work fine.
Thank you!!
There are no execute permission in a build file.

$cd wiringNP
$sudo ./build
command not found

Thank you for usefull library.

My apologies if I am asking this in the wrong place, but i have reached a complete dead end!

I am using a library called node-rcswitch which is reliant on WiringPi.

I am running my project off of a NanoPi NEO so have installed WiringNP as a replacement for WiringPi. node-rcswitch uses the -lwiringPi flag when compiling and does so without error.

However, when i come to use it at run time i get the following error: undefined symbol: wiringPiSetup

Am i missing something with regards to WiringNP? As far as i understand it, WiringNP can be used in exactly the same way as WiringPi. I just can't figure out why its not working at runtime. =(
