v0.3.0

• Added support for the DRV8825 driver
• The DRV8825 driver implementation supports both software and hardware PWM
• Extended the GPIO adapter interface with the method to initialize the PWM channel

v0.2.2

The motor and drivers classes were refactored in a way that the motor class just plays a role of a facade around the concrete driver, but the whole stepping logic entirely depends on the implementation of a particular driver instead of being located in the motor itself.

v0.2.1

Enhance the GPIO adapter interface by the cleanup_pin method which is supposed to be called from the driver's disconnect method

v0.2.0

Bump version to v0.2.0

v0.1.0

Set required ruby version
