Hi folks.

I am failing to get arduino running with PD. As far as I can tell it's all good on the Arduino side (Arduino MegaATK Android) but I cannot figure out how to install the correct externals in PD. [arduino] [compot] [speedlim]

The readme included in the pduino file I downloaded seems to suggest all info is located here: https://lists.puredata.info/listinfo/pd-cvs

I can't figure it out and I am a bit lost. Sorry I''m pretty new to all this.

Thanks in advance for any tips!

Which OS and which Pd are you using? How did you install the [arduino] abstraction and the [comport] object? Where are they located?

OS is El Capitan. Extended PD version.

I did not install anything because I don't know how. I only downloaded the pduino folder.

I am following an online PD guide and trying to move those 3 externals to either of these two folders. (I have no idea what a user specific folder is and google does not seem to help with any info on what they are). Anyway, neither of these folders exist on my harddrive when I do a 'go to folder' search.

I've had some success. The arduino is talking to pure data now. I can get it working fine when I am working with the help file within the 'pduino' folder. But if I save this file to another location the [arduino] object becomes inactive and encircled with a red dotted line. I guess this indicates that I have not actually installed the objects.

@Martinukai Hello, I am not using a mac so I am not absolutely certain that what I write is true, but it is likely that it is......
User-specific will mean for you, as a user, for your login, and so the "~" will be your login name and so you will find it as "you"/Library/Pd if it exists.
Global means for any user of your computer.
Pd needs to be told where things are. When you open the help file in the Arduino folder it has no problem finding the non-help object because it is in the same folder. But if you move it then it has no idea where to find the object, fails, and so you see the red dotted outline and in the terminal a message about the object not being created.

In the terminal window, edit, preferences, path, you can add the places where you store your patches so that Pd can find them. Put your working folder at least, and your desktop maybe.
This aspect of Pd is generally a bit painful, but can be useful if you are trying to run two different versions of Pd as you can stop them finding each other and so getting confused............
Pure data does not have to be "installed"....... it is a portable program, and so you can have a few different copies in different folders (true for Windows..... for osx?).

Under edit, preferences, startup you can add the paths to external libraries that you want Pd to "load" at startup.

I hope that works for you,
If I am wrong about any of that then someone will post and correct me!

As @whale-av said, you need to set the path to the [arduino] abstraction (mind, it's an abstraction not an object - meaning, it's a Pd patch opened as an object). The help patch of [arduino] works because it's in the same directory with the [arduino] abstraction itself. One way to load abstractions to a patch is the patch being in the same directory with these abstraction.
When you try to open [arduino] in another patch (that's not in the same directory with [arduino] itself), Pd doesn't know where to find this abstraction and fails to load it. Once you tell Pd where this is (either via Preferences -> Path..., or by using [declare -path /path/to/arduino_abstraction]) it will find it and load it.

@alexandros @whale-av Thanks so much guys. I figured it out in the end with your help:)
