Description
Mellon GPIO device constructors
sysfsGpioDevice :: OutputPin PinDescriptor -> Device PinDescriptor Source #
Given an OutputPin on a Linux sysfs-based GPIO system, create
a mellon-core Device such that, when the
Controller locks the device, it drives a High
value on the pin, and when it unlocks the device, it drives a Low
value.
Note that the value driven on the pin is its logical value. You
can invert the signal levels by configuring the active level of the
OutputPin.
