changed path for exporting pins

[rexington]

the devices/virtual path wasn't working, but this one does work.

Must just say good job, it works! I am running a pi b +, with recent firmware etc, Did some manual changes to the file that was changed according to this commit, namely the file gpio-admin.c which can be found within the folder structure quick2wire-gpio-admin/src/gpio-admin.c and replaced the path as described in files changed (look at the tab files changed to get a visual). Did a "sudo make uninstall" from within the quick2wire-gpio-admin folder, then "sudo make install" and added the user "sudo adduser $USER gpio" (where $USER is your user..). Logout and login, and then voila it works! :) Just wanted to overexplain some stuff here incase somebody was struggling. But anyways thanks for this fix, good job 👍

[maxbanas]

Thanks all, worked for me too.

[windmaomao]

this works, especially after following DaWoody's comments.

Thanks DaWoody you DaRealMVP

Thanks all,

Successfully rectified my group ownership issue after upgrading. I'm currently running version 3.18.5, model B+. I receive the following in Terminal:

Listening on port 3600
State on received.

The LED connected to GPIO pin #36 FLASH quickly ONCE and turns OFF when pressing 'ON' button on the web server page. The led functioned perfectly prior to the update.

Any suggestions? Thank you!

Hello,

I just followed this fix, but I face exactly the same issue as solaron99 on another GPIO (#4) : the LED flash (and I can hear the relay switch) but quickly and then turns OFF after 1sec...

[ccforward]

There's an answer to fix it.

Why this hasn't been merged yet?

[knocte]

Actually there's a better fix: #7

[lurch]

This hasn't been merged yet because the entire quick2wire software stack has unfortunately been completely abandoned by the original authors.
The last code-commit to any of the https://github.com/quick2wire projects was back in June 2013 :-/

[mstaffeld]

Thanks for the fix.

[crowelch]

Worked great thanks!

[solaron99]

Gentlemen,

I followed your suggestions but fail to resolve my issue.
The LED connected to GPIO pin #36 FLASH ONCE and turns OFF when pressing 'ON' button on the web server page. The LED turned on and REMAINED ON perfectly prior to updating to 3.18.11.

gpio-admin.c :

int size = snprintf(path, PATH_MAX, "/sys/class/gpio/gpio%u/%s", pin, filename);

pi-gpio.js :

var gpioAdmin = "gpio-admin",
sysFsPathOld = "/sys/devices/virtual/gpio", // pre 3.18.x kernel
sysFsPathNew = "/sys/class/gpio", // post 3.18.x kernel
sysFsPath;

app.js :

// Apply command GPIO #36

if (queryData.state == 'on') {
  gpio.open(36, "output", function(err) {     
    gpio.write(36, 1, function() {  
        gpio.close(36);             
            console.log("GPIO Pin 36: " + queryData.state + " received.");                
    });
});
}

if (queryData.state == 'off') {
gpio.open(36, "output", function(err) {     
    gpio.write(36, 0, function() {  
        gpio.close(36);    
        console.log("GPIO Pin 36: " + queryData.state + " received.");                
    });
});
} 

Any suggestions? Thank you!

@solaron99 , try removing the gpio.close(36); lines

[solaron99]

great, thank you! Will keep you posted on the results -ron

Finally got it working thanks to @DaWoody and @rexington !

It would be great to have a robust library with no requirements to abandoned packages, up to date with the latest Raspbian, with better support for RasPi 3 - just working.

I'm new to the Raspi world and really hoped there was better support for NodeJs. Other than these pi-gpio guys' great work there are no viable options to get up and running with building the next IoT awesome products.

[lurch]

I dunno if it's what you're looking for, but https://gpiozero.readthedocs.io is very comprehensive and included in Raspbian by default.

[rbosneag]

Thanks for the tip, it looks very promising.
I was looking for a Javascript library but gpiozero could be a good source of inspiration for many projects and a good guide on GPIO.

[zengdongbao]

thanks guy! is work for me.

[solaron99]

@rmzamith Your solution worked! Thank you.
