Python with mangOH RED wp7702

sebastienmaviel · November 24, 2020, 12:59am

Hello,

I would like to run a simple script using Python with my wp7702 (mangOH Red).

I started following the sample on the Legato docs : tuto legato.

After collecting all the necessary files needed to run the python interpreter thanks to sbtrace, I am getting this error:

Any ideas ?
Thanks !

is your script ok to run in terminal?
Is that you must run python script inside legato application?

sebastienmaviel · November 24, 2020, 11:06am

I want to run it inside a legato application and I want to then import the system libraries and additional libraries

jyijyi · November 24, 2020, 11:22am

Can you unsandbox the app and run by system()?

sebastienmaviel · November 24, 2020, 11:44am

Nothing seems to happen when I use system. Maybe I am wrong with the commands, what should I type ?

jyijyi · November 24, 2020, 11:48am

system() is not command, it is a API called in the program.
e.g.

system(“python helloworld.py”);

sebastienmaviel · November 24, 2020, 11:55am

Ok, so in my .adef, instead of: python .hello.py.
I type: system(“python hello.py”) ?

jyijyi · November 24, 2020, 11:58am

you should modify your .c file and add
system(“python hello.py”)

sebastienmaviel · November 24, 2020, 12:14pm

Ok, I got this now:

I don’t see problem, you can use my attached hello6.rar.

Thanks for your support, works fine when i create my python script from the mangOH.

However, it looks like I failed to bundle new files from my laptop to the mangOH (using .adef)

After trying this in my corresponding .adef:

bundles:
{
    dir:
    {
		[rx] "/home/maviel/Documents/legato_workspace/apps/helloPy/scripts"	"/scripts"
        [rx] "/home/maviel/Documents/legato_workspace/apps/helloPy/scripts"	"/home/root/scripts"
	}
    file:
    {
        [rx] "/home/maviel/Documents/legato_workspace/apps/helloPy/scripts/hello.py"	"/home/root/"
    }
    
}

I can not find my files in my mangOH at the corresponding directories.
Any ideas why ?

FYI, here’s my app: helloPy.zip (2.1 KB)

jyijyi · November 24, 2020, 4:14pm

You can see here on how to bundle file

github.com

legatoproject/legato-af/blob/master/apps/test/audio/audioPlaybackRec/audioPlaybackRec.adef

executables:
{
    audioPlaybackRecTest = ( audioPlaybackRecComp )
}

maxFileSystemBytes: 5000K

bundles:
{
    file:
    {
        [r]     audio/0-to-9.wav   /usr/share/sounds/
        [r]     audio/male.wav     /usr/share/sounds/
        [r]     audio/0-to-9.amr   /usr/share/sounds/
        [r]     audio/0-to-9.awb   /usr/share/sounds/
        [rw]    record/remote.wav  /record/
        [rw]    record/samples.pcm /record/
    }
}

This file has been truncated. show original

sebastienmaviel · November 24, 2020, 10:47pm

Thanks, it’s working.
For info, I found a curious behavior.

The script displays on the console only when the script is terminated (which doesn’t happen when using the shell directly from the mangOH).
The issue is if the script is meant to never end, nothing will be displayed on the console.

jyijyi · November 24, 2020, 11:04pm

You should run in console instead of legato app if you want to print in console
