gpio-sysfs

Module to control GPIOs using the sysfs interface original docs sysfs docs

Differences

• error return codes have been removed, catch Exceptions with try/except instead
• replaced Constants with Enum members, all methods now accept and return those (or raise a ValueError)
• pointless makefile removed
• the export of the sysfs interface now takes place when the class is initialised instead of when a method is called
  • the sysfs interface has to be unexported to prevent errors
• the unexport of the sysfs interface now takes place when the release method is called instead of when a method finishes
  • has to be called once and is automatically called when using the class as a context manager (with OnionGpio(i) as gpio:)
• added the supportsDirection and supportsEdge methods to check if these settings can be changed
• added the getEdge, setEdge and waitForEdge methods
  • getEdge returns the edge setting of the GPIO
  • setEdge(edge) is setting the edge setting of the GPIO
  • waitForEdge(timeout=None) waits for a edge to occur or the timeout to run out if not None (raising a TimeoutError)
• added the ignore_busy paramter, which ignores the OSError raised when the interface is already exported (default = False)
• exposed the setDirection(direction) method which is setting the direction setting of the GPIO to direction
• exposed the setActiveLow(active_low) method which is setting the active_low setting of the GPIO to active_low
• removed original setActiveLow and setActiveHigh
• removed multiple input checks, use the Enums of this module to interact with the methods
  • Value contains supported GPIO values
  • Direction contains supported GPIO directions
  • ActiveLow contains supported active_low settings
  • Edge contains supported GPIO edges
• removed at least one occasion of Error hiding
• removed the verbose argument, logging should be done by the application itself
