https://wiki.openwrt.org/doc/hardware/port.gpio
in BB
echo "29" > /sys/class/gpio/export
but in CC it seems to be
echo 29 > /sys/class/gpio/export
without the quotes does the old way need to be preserved?
Then this wiki page mainly talks about sending GPIO signals
Also it would be nice to add info on reading a GPIO pin
to activate GPIO14:
echo 14 > /sys/class/gpio/export
to set as input
echo in > /sys/class/gpio/gpio14/direction
and then read the value with:
cat /sys/class/gpio/gpio14/value
output value will be displayed as 0 or 1
Tough it would damage the flow of the document when i dont add this carefully.
I see many wikipages with an odd flow. And also ones that are really good.
My biggest concern is how to add to a page without damaging the work that is already there.
Writing a forum post is one, but improving a wikipage can be daunting even with a simple addition like this.
What is the policy? Just add it, try my best and hope it works out well, or be more careful about it?
