Hi,
i use v 3.02 & i want to use more than 1 gpio as output for switching a relay( min 8, 16 would be better )
i do not use dac's , so there are free .
this link http://raspberrypiguide.de/howtos/ra...i-gpio-how-to/ show the general workflow.
if i go to /sys/class/gpio, then there is only 1 avail gpiochip0.
how to add more ?
