GPIO library - WiringPi

wlohrum

Hello there. Thank you all for you valuable and hard work!! Sutch a strong and active comunity is the only thing that adds some value to the orangepi.

As for wiringX: in the list of supported devices there is no reference to orange pi (interest in working with orange pi pc). Is it compatible even if not included in the readme?

Thanks!!

apocalyps

there is indeed no reference because until my version is wasnt supported. I wrote a module for orange pi and put it on github. As a source i used parts of the wiringOP code from werecatf. So if you take my version from github you are be able to do some testing with wiringX on your orange pi. Im still improving it by some little tests so not everything is allready working 100%

Good day, my friend!
I'm interested using i2с.  Original WiringPi for Raspberry Pi supports PCF8574.
Proof.
I'm sure you know about it

I want to use it in your library.But he is seeking at the wrong device i2с.

3. Error: Could not open file `/dev/i2c-2' or `/dev/i2c/2': No such file or directory

5. root@OrangePI:/dev# gpio i2cd

Can you fix it?

Good day, my friend!

There is a bug in gpio i2cd.
Please modify a source and re-build library once again.

/home/orangepi/WiringOP/gpio/gpio.c


[before]

1. 
   
2.                 if (!moduleLoaded ("i2c-sunxi"))
   
3.                 {
   
4.                   fprintf (stderr, "%s: The I2C kernel module(s) are not loaded.\n", argv [0]) ;
   
5.                   //return ;
   
6.                 }
   
7. 
   
8.                 sprintf (command, "%s -y %d", I2CDETECT, 2) ;
   
9.                 if (system (command) < 0)
   
10.                   fprintf (stderr, "%s: Unable to run i2cdetect: %s\n", argv [0], strerror (errno)) ;

I sent PULL-REQUEST to github.
I think that it will fix soon

I was able to control a 120 volt power strip with mine. https://www.youtube.com/watch?v=Zh7QMcEfT_Q

Hey , this works for me perfectly through the terminal . But on a Web server that does not work . I ...

I use almost no php, so it may not be a right response.
It may be a problem of path.

So try this

<?php shell_exec("Full_Path_of_python Full_Path_of_GPIO/examples/on.py"); ?>

or

<?php
$fullPath = 'Full_Path_of_python Full_Path_of_GPIO/examples/on.py';
exec($fullPath, $outpara);
?>

Hello.
I'm having trouble using SPI. All other interfaces are working, but in SPI it isn't outpuing any data.

Is there any nuance for it?
I'using the following library https://github.com/zhaolei/WiringOP
Thank you.

Armen

Ok, I fix it. Channel number should be 0 in my case.

Hello,

This is compatible with orange pi zero (13*2 pinout) ?

Please give me a code to blinking led in orange pi lite.
I have installed wiringOPi library.
