Re: [PD] how to install and use GPIO external
Hey Josh, In the gpio folder, do you have 'gpio.l_arm' ? i386 is for a different processor type and the rpi is arm. Keep going, you're nearly there:) Julian On 18 June 2013 22:37, Josh Downing jndown...@gmail.com wrote: Sorry for attaching the pics. Will avoid this in the future. Julian, you are right, I have not compiled it. I did not know how to do this.

Josh, sounds like you haven't compiled the external yet. My memory (and I'm guessing here, don't have a Pi to confirm atm) is this: from the command line cd (change directory) to the gpio folder (wherever you've put it on the pI) and type 'make'. Check the command line doesn't spit any errors and in theory there should be a gpio external sat in the gpio folder at the end of it. Maybe you've done this already and it's compiled happily? In that case you need to tell Pd where the external is - a good place to put it would be in the 'externals' folder. puredata.info is your friend here.

Re: [PD] how to install and use GPIO external
Thanks Jaime, that fixed my error problems. No errors now but I can't seem to figure out how to set the patch up to configure GPIO 17 as an input and then to read the state. I modified gpio-help.pd to do this by changing output 1 to output 0 (according to the patch output 0 should configure the pin as an input). I then click enable 1, open 1, and then output 0. No error messages but where should I expect to see the high/low state of GPIO 17? Should this be reflected in the bang object in the script (white for low and black for high)? I have the poll input check box checked. When I toggle the voltage on GPIO 17 from 3.3V to GND I do not see anything change in the script.

No error messages but where should I expect to see the high/low state of GPIO 17? it should come out of the object into a number box or toggle as far as I can remember... put a number box in the outlet of the gpio object. J Should this be reflected in the bang object in the script (white for low and black for high)? I have the poll input check box checked. When I toggle the voltage on GPIO 17 from 3.3V to GND I do not see anything change in the script. I am able to see the high/low state of the pin 17 change by using the readall command from LXTerminal so I know that I'm switching the voltage correctly on the right pin, just not seeing how I get this status in pure data using the gpio-help.pd script. Any thought on how I do this? Sorry I have very little experience with pure data and am just learning.

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. In the gpio-help.pd patch I would click enable 1 and then click open 1 and after clicking open 1 I would get an error message: /sys/class/gpio/gpio17/value: No such file or directory. I then realized that I probably needed to install wiringPi. I downloaded this and installed it. However I would still get the previous error message within PD. 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. I then loaded the gpio-help.pd file again in PD. Now once I click open 1 instead of the no such file or directory error I get /sys/class/gpio/gpio17/value: Permision denied error. 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? Almost there!

Re: [PD] how to install and use GPIO external
i'm not very familiar with the specific help-patch, but i do know a bit of Pd The joy of understatement. Josh, sounds like you haven't compiled the external yet. My memory (and I'm guessing here, don't have a Pi to confirm atm) is this: from the command line cd (change directory) to the gpio folder (wherever you've put it on the pI) and type 'make'. Check the command line doesn't spit any errors and in theory there should be a gpio external sat in the gpio folder at the end of it. Maybe you've done this already and it's compiled happily? In that case you need to tell Pd where the external is - a good place to put it would be in the 'externals' folder. puredata.info is your friend here.

Re: [PD] how to install and use GPIO external
Sorry for attaching the pics. Will avoid this in the future. Julian, you are right, I have not compiled it. I did not know how to do this. When I navigate to the directory that I have unzipped the files (home/pi/pd-externals/gpio) and then type make it prints the following: cc -DPD -O2 -funroll-loops -fomit-frame-pointer -fno-strict-aliasing -Wall -W -Wshadow -Wstrict-prototypes -Wno-unused -Wno-parentheses -Wno-switch -I../pd/src -I../../pd/src -I../../../pd/src -I../../../../pd/src -I../../../../../pd/src -m32 -o gpio.o -c gpio.c cc1: error: unrecognized command line option ‘-m32’ make: *** [gpio.l_i386] Error 1 Do you know what this error message could mean? What should I expect as the output from compiling like this? Not sure what I should be looking for. I did notice that this output looks like what is listed in the makefile.include that is in the root directory of the zipped archive (pi-externs.tgz).
