Hi list,

I could make use of gpio (as output) within pd with just [textfile] :

on the command-line:

echo gpio17 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio17/direction chown charles /sys/class/gpio/gpio17/value

inside pd:

[ set 1 ( [ write /sys/class/gpio/gpio17/value cr ( | [ textfile ]

works.

could I do the reverse here? I mean, use it as an input rather than an output? would it be something like:

echo gpio17 > /sys/class/gpio/import echo in > /sys/class/gpio/gpio17/direction chown charles /sys/class/gpio/gpio17/value

inside pd:

[ set 1 ( [ read /sys/class/gpio/gpio17/value cr ( | [ textfile ]

Replacing "charles" (after chown) by your user and [set 1( by [rewind, bang( should work. ++
