A PHP library to play with the Raspberry PI's GPIO pins

php-gpio's Issues

Support for Raspberry Pi 3

For my Raspberry Pi 3 it doesn't detect the right version number in Pi->getVersion(). It returns 0 instead of 4. Therefore I can't use certain pins without it complaining. I would have made a pull request if I could but I don't know how to convert the revision numbers (http://www.raspberrypi-spy.co.uk/2012/09/checking-your-raspberry-pi-board-version/)

"git was not found" when installing from composer

(received from David P., I write it back here in case it serves to others users )

I have tried to install the php gpio library and I seem to be running into a problem. Please forgive me, I am a beginner. I'm sure I'm missing something very fundamental :)

Following instructions at https://github.com/ronanguilloux/php-gpio

When I try to execute

php composer.phar create-project --stability='dev' ronanguilloux/php-gpio intoYourPath

I get an error

Permission Denied - file_put_contents(/sys/class/gpio/gpio23/direction): failed to open stream: Permission denied

Hi there, i'm using your package with Laravel 5.5 and Nginx+Php-fpm
I had a problem:

file_put_contents(/sys/class/gpio/gpio23/direction): failed to open stream: Permission denied

Any idea?

getVersion() not working on B+

This line is not working with B+ version (revision 0010).
https://github.com/ronanguilloux/php-gpio/blob/master/src/PhpGpio/Pi.php#L12

Looking in revision tables, maybe just with a return hexdec($matches[1]) gone work.

Permissions for Exec

Hi,

I have been dealing with the Exec command, and the only way that worked for me was exec('sudo php blinker 17 20000');

It needed the php command, is this a permissions issue? It works fine localy, but through the network it doesn't.

Permissions are not set, pelase provide example

Hi There.

I am sorry to bring this up, but could the permissions settings also be addressed here more, because this does not work without them, using Raspberry Pi2 and Jessie 2017 image.

When user starts this from the pure clean jessie image and installs apache2 with php5 pi user loggind in, , GPIO permissions are not right and this does not work. Sudo php index.php does the trick.
I would ask for clean commands on how to make this work.
After Apache2 & PHP installations, I use "sudo chown pi.pi /var/www/html -R" so that I can SFTP stuff in.

Thank you for your considerations.

Raspebrry Pi A+ & version 2 support

I'm putting here an email from Jack **** about Raspebrry Pi A+ & version 2 support:

Dear Ronan Guilloux
At First Thanks For make the Project php-gpio and share with us.
I have a Question may i know is this Project Support the Raspberry-Pi A+ or Raspberry-Pi 2 ?
I have Test this in My Raspberry Pi A+ with a simple LED blink but fail.
So just want to make sure for this.
Thanks

My (typo fixed) answer, and the things to do are:

Hello Jack ****!
AFAIK, A+ & 2 versions are not supported yet, but it wouldn't be a big deal to add such support, since you just have to find the right list of GPIO pins to add in the Gpio class constructor.
These GPIO pins lists for both A+ & Raspi 2 may probably be found in the Raspberry Pi public specifications. Other (unofficial) specs are already online, but a deeper check on that, from you or someone else would be nice.
So, do not hesitate to contribute & to enhance our GPIO pins list, in order to support these new Raspi models !

Pin number 16 invalid

Im trying to convert this python https://gist.github.com/gsdevme/3ac674eb105b13d0139d

I have repo setup here https://github.com/gsdevme/energenie-pi-remote-control however running it on the Pi I get pin number 16 invalid

https://github.com/gsdevme/energenie-pi-remote-control/blob/master/test.php

# set the pins numbering mode
GPIO.setmode(GPIO.BOARD)

The python has this call unsure if its a problem, any ideas exactly?

Update credits

Hey,

Can we update the URL from https://github.com/pickley/PHP-GPIO to https://github.com/aaronpearce/PHP-GPIO.

Just changed my Github name so the link will 404 :)

PWM support

Could it be possible to support PWM (Pulse Width Modulation)?

Raspberry Pi B+ version's GPIO hackable pins array always empty

in a Raspi B+ case, getHackablePins() returns an empty array.

Permissions Issue

I seem to be having a problem controlling the GPIO pins using this script.

It seems to stem from the fact that the directories in

/sys/class/gpio

and their symlinked companion

/sys/devices/virtual/gpio

keep reverting back to being root:root.

Additionally, if I set the ownership to pi:pi and add read/write to group permissions the directory for the pin I'm accessing empties itself.

I feel like I'm missing something really obvious. At the moment my Apache server is running as pi:pi. What permissions and ownership do I need to set to make this work?

Clarification on API

The API can only be used with sudo permissions correct? The blinker file is separate and used for secure cases, but there is no safe/secure way to use the API for a web based application?

Thanks

run servomotor using this library

Hi
I am trying to simulate PWM by writing this code to run a servomotor

#!/usr/bin/env php
<?php

require 'vendor/autoload.php';

use PhpGpio\Gpio;
$gpio = new GPIO();
$gpio->output(18,0);
while(true)
{
$gpio->output(18,1);
usleep(1500);
$gpio->output(18,0);
usleep(2000000);
}

but the servo is not working, a similar code is written in python on this video and it is working: http://www.youtube.com/watch?v=ddlDgUymbxc&feature=youtu.be

any ideas?
