How do I install this external? I can open the gpio-help.pd file in pure data but when I try to open it I get the attached error message (pd_error_message.png). I assume this is because I haven't installed the external. I copied the contents of the pi-externs.tgz file that I downloaded from Miller's site into the following path on my pi: "/home/pi/pd-externals/". Isn't there something else I need to do though to install this so that I can use it in PD?

Also, once I get this installed I want to setup GPIO 17 as an input and then read the state of it. I'm going to alternate between applying 3.3V and GND to the GPIO 17 pin and I would like to see the high/low status of the pin change in pure data. See attached screenshot (gpio_help_configuration.png) for how I configured Jaime's gpio-help.pd file to do this. All I did was change output 1 to output 0 so that GPIO 17 would be configured as an input. If I want to see the status of the pin what will I look at in this script to see the high/low status of the pin? Do I need to modify this script in any other way to be able to see this?

Really appreciate your help!
Josh

Hi Josh,

The thread you're after is this one:

gpio on the raspberry pi from within pd ?

(ooh - big font)

And Jaime's helpfile's attached.


That should do it.

I'm trying to figure out how to use the [gpio] external and I'm totally lost on how to install it and then how to use it inside PD on my raspberry pi. I did download the external from Miller Puckette's website but that is about as far as I have been able to get. I would like to be able to configure 4 GPIO pins as inputs and read their state within my PD patch.

Could anyone provide me with any help on how I would go about installing this patch and using it in PD on the pi? Also, I found a thread in the list serve archive where someone had attached a draft of instructions on how to install and use the GPIO external but unfortunately the attached file was not available. Could someone send me these instructions if you have them?

Thanks,
Josh
