When I toggle the voltage on GPIO 17 from 3.3V to GND I do not see anything change in the script.

So I deleted the "-m32" from the makefile and then everything seemed to build okay. I then added the correct path for the extension in pure data and loaded the "gpio-help.pd" patch without getting an error message.

I then decided to manually try to create the file using commands in LXTerminal. I did this using this command, "echo "17" |sudo tee /sys/class/gpio/export". I then noticed that the gpio17 folder and accompanying files were created. I was also able to correctly read the state of the pin using "gpio readall" command from LXTerminal.</div>
<div><br></div><div>I then loaded the "gpio-help.pd" file again in PD.

Is there someway I can use this GPIO library within the PD visual interface without getting permission denied errors? Also, shouldn't clicking "enable 1" within the gpio-help.pd patch create the "/sys/class/gpio/gpio17" folder and accompanying files? How can I get this to work within PD without having to run the commands from LXTerminal to create the folder/files? Do I need to somehow indicate to pure data the path of wirngPi?</div>

</div>it means that the makefile has a compiler flag "-m32" which is not<br>
known to the compiler.<br>
<div><br>

<br>
</div>nothing. the build failed.<br>
<br>
you could try editing your makefile and removing the "-m32"<br>
occurences, and see what you get then.<br>
<br>
make a backup of the makefile, before you go ahead.<br>
