Hello,
I'm trying to play with the GPIO on bbb. I must be
misunderstanding how this is supposed to (expected)
to work.
I've been looking through the gpioctl (gpio) manuals,
but i'm still confused, and could use a pointer.
here is a demo:
# gpioctl gpio1 7
pin 7: state 1
# gpioctl gpio1 7 off
pin 7: state 1 -> 0
# gpioctl gpio1 7
pin 7: state 1
hmm...
# gpioctl gpio1 7 off
pin 7: state 0 -> 0
err... help?
Hi,
The direction of the pin has to be configured at securelevel 0.
You can put something like the following line in /etc/rc.securelevel:
gpioctl gpio1 23 set out
Then you should be able to toggle the pin:
# gpioctl gpio1 23 on
pin 23: state 0 -> 1
# gpioctl gpio1 23 off
pin 23: state 1 -> 0
