Or you can still use https://github.com/gonzoua/freebsd-gpio

If you find examples there too "example-ish", I use it like this:
http://ketas.si.pri.ee/bbb/bbb-poe-daemon/util/gpio.pl
(pin config part needs rewrite to remove gpioctl exec)
Well, only if you and / or him likes Perl.

There is also new GPIO code somewhere, which supports features like
interrupts. I haven't really seen it or tried to get that working (loos@
& rpaulo@ likely know more). I also don't know about RPi, I only have
BBB which I can say works well and has lot of features, including some
unsupported ones.
Curses per some time period seems higher with RPi. Though, it's cheaper
device... And you already have it.
