New version to support Raspbian kernel 4.9.y ?

[gundrygs]

Hi, I see that the guys @ https://github.com/raspberrypi/linux have changed the Linux headers default branch to 4.9.y, and are expecting this to be the new Long Term Support (LTS) version. This causes an issue for wiring-pi when using a 4.9.y Raspbian kernel, as the kernel (correctly) reports the hardware on a Pi3 as 'BCM2835', but this generates an error message regarding unsupported hardware in wiring-pi. It appears Gordon Henderson fixed this issue some time ago in the C library for wiringPi (http://wiringpi.com), but your Node wrapper builds against a rather out of date mirror at https://github.com/nekuz0r/wiringpi.git. Do you plan to resolve this ? Regards, George

I took a stab at changing the target to a more up-to-date WiringPi lib, but I'm seeing failure at node-gyp rebuild. I don't have much experience making/updating binding libraries, so I'm not sure where to go from there.

Hi Ross,

I have had success replacing the "wiring-pi" library with the "wiringpi-node" library - just had to npm install and change the require statement in my code - worked on the new kernel without further modifications.

See https://www.npmjs.com/package/wiringpi-node

Hope this helps,

George

I forked this repository to use the latest library.

Is anyone working on resolving this issue for real? I was able to use @kohei0302's fork to get running again (thanks for that!), but that's no substitute for a real fix. I can't tell if anyone is actively maintaining this project -- @eugeneware are you on top of this? Has this project been superseded by a different node.js wrapper for WiringPi?

Hello

I am trying to install wiring-pi module for nodejs but I am facing some problms. Here you can see all I have tried: -Install Raspbian laste version Version:July 2017 Release date:2017-07-05 Kernel version:4.9 -Make an sudo apt-get update / upgrade -sudo apt-get install npm. -npm install wiring-pi -npm install wiringpi-node -node - v v0.10.29 -npm - v 1.4.21

when I run a in /home/pi/node-modules/wiringpi-node/examples: sudo nodejs bink.js I have the same problem with the BCM2835.

I had install wiringPi lib with the last version. I have no problem in command line with gpio cmd, but that doesn't work with node. In the package wiring-pi and wiringpi-node the version of wiringpi is 2.44

What am I doing wrong ? I don't understand. I read the issue problem with the "Bump to wiringpi-node 2.4.4" but i dont understand what to do and where are files to modify.

Thank a lot for your help.

I only npm installed 'wiringpi-node', not both libraries - note that you will need to change the 'require' statement in your code - for example, change "const wPi = require('wiring-pi')" to "const wPi = require('wiringpi-node')"

Without this change in both your code and the blink example, you will continue to reference the original wiring-pi library, and so continue to see the problem.

Hope this helps.

Hello thank for your answer.

I had reinstalled all the raspbian next npm and wiringpi-node with npm. In the file /home/pi/node_modules/wiringpi-node/examples/blink.js I change the require : var wpi = require('wiring-pi'); By: var wpi = require('wiringpi-node');

I have this error : pi@raspberrypi:~/node_modules/wiringpi-node/examples $ sudo node blink.js

module.js:356 Module._extensions[extension](this, filename); ^ Error: Symbol WiringPi_module not found. at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Module.require (module.js:364:17) at require (module.js:380:17) at Object.

Thank for your help

Have you tried copying blink.js to your /home/pi directory and running 'sudo node blink.js' from there ?

[val34m]

Hello

I tried to create a new file name test.js

I just have written the require statment And i have the same issue

Is node version v0.10.29 is good ?

Thank

[val34m]

Hello

After many tests, i have found what didn't worked. we need to use node version 6 and not v0.10.29.

blink.js work fine.

Thank for the support, and for the great job

[gundrygs]

I am very pleased you managed to "crack the case" 😊

Hello

I 'have an other problem :(

I tried to configure a pca9685 module so this is what i tried : => create a file pca.js In this file : var wpi=require('wiringpi-node'); wpi.pca9685Setup(100,0x40,50);

When i tried this i had : TypeError: wpi.pca9685Setup is not a function

SO i tried to liisted all fonctions in wpi with a console.log(wpi); I can see they have no fonction pca9685

How to use pca9685 module ? I have se same problem for mcp23017

Thank

[RandScullard]

WiringPi doesn't have drivers for specific devices. You need to either find a node.js driver for your device or write your own. It looks like there are existing drivers for the pca9685 (https://github.com/johntreacy/adafruit-pca9685) and mcp23017 (https://github.com/kaihenzler/node-mcp23017) so you should check those out. I haven't used either of these devices so I can't vouch for the drivers. For the most part I've found that I've had to write my own drivers for the devices I've used so far; often this is a matter of porting existing Python code to JavaScript.

Interesting note: Neither of the drivers mentioned above actually uses WiringPi-Node.

Hello

Thank for the answer. I had asked that beacause in the documentation they have mentionned in extension part these modules

[kishu27]

bumping this issue. Maintainers, please consider this issue as it's being a blocker now

I'm going to rewrite the whole project. I had alot of ideas to make the project more open for me and other contributors by moving it to an open organization see #61. I also opened an issue #60 about moving to NAN. But just as I started my work on rewriting last year I received a life changing opportunity for me which I could not reject. On top of that I'm currently studying mathematics and computer science verry seriously, so I had no time for this project. Now I have whole month free just for me and I'll use it to contribute to project like this one ;) Sorry for he novel about my life but I have to explain why #60 is still open ...

[kishu27]

Haha.. totally understand :) If for the time being, it's not so much of a problem, maybe you can consider merging https://github.com/kohei0302/WiringPi-Node

[NoHomey]

@RandScullard I've checked both repos. They are using only I2C bus. i2c npm package they use ships with I2C device driver this way it has an interface talking directly to the hardware and so no need to use WiringPi lib ...

[NoHomey]

@kishu27 I'll write to @kohei0302 asking him to make a PR which I can than merge.

[kishu27]

Thanks

[NoHomey]

@kishu27 I have not found any contact to @kohei0302 so I made the PR with which to merge the commits from his fork. The problem is that @kohei0302 's fork builds against his fork of wiringpi as well ... So I'wont merge the PR before @nekuz0r reviews it.
