Hi,

I have installed Pure Data Extended on a Raspberry PI and it works fine
(with "pd-extended -nogui -noadc -alsa test.pd") except keyboard input via HID library (doesn't receive keys when -nogui is active, I'm going to use a Arduino for that since i need analog input anyway).

Now I want to shutdown the raspberry pi after pd is done.
Is it possible to send command from Pure Data to the Raspbian terminal (like "sudo shutdown -h 0")?

Greetings, Himi

@himijendrix Sure! Use [shell].

Cheers~

If you use input from an Arduino to contro shutting down the Pi, make sure you use [change] (especially for digital input, and if you're using INPUT_PULLUP or pull-up resistors, then use [change 1]) because it will send the command at baud rate causing a crash, or ever causing your patch to shut the Pi down as soon as you open the patch. I had that in the past, that's why I'm writing this....
