pycomedi 0.4

An object-oriented interface for the Comedi drivers.

This package provides an object-oriented interface to the Comedi drivers. The standard Python interface bundled with Comedilib is a simple SWIG clone of the C interface. In pycomedi, we convert the functions into class methods (see pycomedi.classes), so you don’t have to worry about dragging around opaque types like comedi_t * device pointers. We also bundle related constants together in _Enums and _Flags (see pycomedi.constants), to make handling common operations like flag manipulations simpler. Finally, there are a number of utility classes (see pycomedi.utility) to make common tasks like creating instructions or reading hardware-timed analog input easier.
