Got the difference between OPI PC and OPI Zero mapping. Its working fine now.

Any chance you would share that info? I'm having the same issue.

ok, figured out most of it, and updated readall.c, pins 19, and 21 still haven't figured out... but...

diyer

can someone explain how to map wiringPO on zero plaese?

Please use WiringOP-ZERO

https://github.com/xpertsavenue/WiringOP-Zero

It have compatibility of the pin number.
But if you operate GPIO using device file,ZERO don't have compatibility to OPI-PC.

You can know this difference in [gpio readall] command.

Operate Pin#18 with OPI-PC

$ sudo sh -c "echo 71 >/sys/class/gpio/export"
$ sudo sh -c "echo out >/sys/class/gpio/gpio71/direction"
$ sudo sh -c "echo 1 > /sys/class/gpio/gpio71/value"
$ sudo sh -c "echo 0 > /sys/class/gpio/gpio71/value"
$ sudo sh -c "echo 71 > /sys/class/gpio/unexport"


Operate Pin#18 with ZERO


$ sudo sh -c "echo 18 >/sys/class/gpio/export"
$ sudo sh -c "echo out >/sys/class/gpio/gpio18/direction"
$ sudo sh -c "echo 1 > /sys/class/gpio/gpio18/value"
$ sudo sh -c "echo 0 > /sys/class/gpio/gpio18/value"
$ sudo sh -c "echo 18 > /sys/class/gpio/unexport"

In case of Python, you can use there library.

orangepi_PC_gpio_pyH3
https://github.com/duxingkei33/orangepi_PC_gpio_pyH3

WiringPi-Python-OP
https://github.com/lanefu/WiringPi-Python-OP

But there library pin assin is not same.

You can update WiringPi-Python-OP to WiringPi-Python-OP-ZERO.

1.Download [WiringOP libary for the Orange Pi Zero] from here.

https://github.com/xpertsavenue/WiringOP-Zero

2.Download [WiringPi-Python-OP] from here.(But not Install)

https://github.com/lanefu/WiringPi-Python-OP

3.Replace base library

cd WiringPi-Python-OP
rm -R WiringPi
cp -R $HOME/WiringOP-Zero ./
mv WiringOP-Zero WiringPi

4.Build WiringPi-Python-OP-ZERO library

sudo apt-get install python-dev python-setuptools swig
swig2.0 -python wiringpi.i
sudo python setup.py install
cd tests
sudo python test.py

WiringPi-Python-OP-ZERO have there pin.

This is same as RPI TYPE A or B

for orange pi zero I found this

https://github.com/xpertsavenue/WiringOP-Zero

BobbyBalsa

this one works for the zero , out of the box :OPI-zero

and a nice tutorial , in German :
OPi zero first steps
