Odroid U3: edge file needs to be reset on start

[noniq]

I’m using this awesome gem for a project with an Odroid U3. The relevant lines from the script are simply:

after pin: 199, goes: :high do
  # do something
end
PiPiper.wait

Everything works fine when I the script is started for the first time. However, if the script is stopped (Ctrl-C) and then started again, the block is no longer called even if the pin changes.

It found out that this can be fixed by “resetting” the edge file at the start of the script like this:

File.write "/sys/class/gpio/gpio199/edge", "none"

Should this be included in pi_piper?
