#28920 Hi all,

that function doesn't work with that pin,
it generates an continously toggle of the pin, observed with a scope.
the function leads to software crash, flooding serial output with unprintable char's,
just try a simple test to reproduce in init.lua:
pin = 7
ow.setup(pin)
ow.reset(pin)

no problems with i.e. pin 4
module is a ESP-03
NodeMCU 0.9.6 build 20150704 powered by Lua 5.1.4
tried float and integer

any hints ?

Regards,
