#52 'Unallocate' a pin

[Ben Croston]

Requested by @cymplecy
Will add GPIO.NONE as well as GPIO.IN and GPIO.OUT for GPIO.setup() calls

[Ben Croston]

Si - do you want it to clean up the pin when you GPIO.setup(channel, GPIO.NONE) i.e. return the channel to INPUT and remove pullup/down and any events?
Alternative - RPi.GPIO leaves the pin as configured and just 'forgets' about it (like when you don't run cleanup() ).

[Simon Walters]

Yes - return it to state it would have been in had it never been used for anything please :)

[Ben Croston]

So GPIO.cleanup(channel) call then?

[Ben Croston]

GPIO.cleanup(channel) fix now in source code library. Will be part of next release. I will make the next release as soon as you have tested this fix.

To install the dev version with this fix:
$ sudo apt-get remove python-rpi.gpio python3-rpi.gpio
$ sudo apt-get install python-pip python3-pip python-dev python3-dev
$ mkdir ~/temp
$ cd ~/temp
$ sudo pip-2.7 install -e hg+http://hg.code.sf.net/p/raspberry-gpio-python/code#egg=RPi.GPIO
$ sudo pip-3.2 install -e hg+http://hg.code.sf.net/p/raspberry-gpio-python/code#egg=RPi.GPIO

To remove the dev version and switch back to the Raspbian default version:
$ sudo pip-2.7 uninstall RPi.GPIO
$ sudo pip-3.2 uninstall RPi.GPIO
$ sudo apt-get install python-rpi.gpio python3-rpi.gpio
