WebIOPI is not working yet on Raspberry Pi 2.

There are things that You can do to change it.

You must change two files located in /python/native directory.

First change setup method in gpio.c file
Second change get_cpuinfo_revision method in cpuinfo.c

I've attached two needed files.

When you replace files in sources You must install it once again.
Then it should work on RPI 2! :)

I can't find /python/native where is it located ?

Got it working after replacing the said files.

Noticed that GPIO list shows only up to pin 26. Pins 27 to 40 is not present.

Also use RPi 2...

Do you know when the WebIOPi 0.7.2 will appear ??

Original comment by MisterLo...@gmail.com on 25 Feb 2015 at 7:57

GoogleCodeExporter commented 9 years ago 
to use pins 27 to 40 you must change a lot in WebIOPi...

First You must change version.py to handle new pins.

second you must do some changes in webiopi.js

Sorry i wasn't able to post an update earlier.

I got it to show all pins the other night by modifying the mentioned files 
(namely version.py under python/webiopi/utils folder and webiopi.js under 
htdocs folder).

Everything seems ok except that I noticed pins #29 (GPIO 5) and #31 (GPIO 6) 
were not as the same as the rest in terms of default status.

Under GPIO header, it shows that GPIO 5 has a default status of OUT,HIGH, while 
GPIO 6 has IN,HIGH.

I don't know if it means anything. Just wanted to share what I experienced. 
Thanks for the help by the way regarding the two attached files under 
python/native folder...

in my pi gpio #5 and #6 are in default state IN and HIGH signal...
there is a config file where you can change the start state of pins..
just sudo nano /etc/webiopi/config

Yes cross fingers that a new version will be released soon...
Would also be intrested in the modified webiopi.js

Thanks

After replacing the two files in the source and reinstall worked for me. Thank 
you.

Thanks for posting the files. they work perfectly on my pi2.
i do also have the pins 5/6 in IN and HIGH state, but that actually doesnt 
bother me.

This worked for me too. Just to make it a little easier for the next person, 
download the above files and then, with those in your home directory, and with 
your current working directory in $HOME/WebIOPi-0.7.1, assuming you've 
extracted the sources there, the following are the mv commands to put these 
files into place:

pi@raspberrypi ~/WebIOPi-0.7.1 $ mv ../gpio.c python/native/gpio.c
pi@raspberrypi ~/WebIOPi-0.7.1 $ mv ../cpuinfo.c python/native/cpuinfo.c
pi@raspberrypi ~/WebIOPi-0.7.1 $ mv ../version.py 
python/webiopi/utils/version.py
pi@raspberrypi ~/WebIOPi-0.7.1 $ mv ../webiopi.js htdocs/webiopi.js

Adjust your paths if you've got things in different places. Then run setup.sh 
and you're good to go.

Thanks to everyone who has contributed to this - very cool!
