Method Detail

getServoPulseWidth

public int getServoPulseWidth()

Description copied from interface: ServoDriver

This method returns current servo pulse width. Zero may represent this driver stopped producing pulses. Also, value of -1 may define undefined situation when this abstraction didn't get initial value yet and there is no way telling what real, hardware or software driver is sending.

Specified by:

getServoPulseWidth in interface ServoDriver

Returns:

current servo pulse this driver is producing

setServoPulseWidth

public void setServoPulseWidth(int width)

Description copied from interface: ServoDriver

Sets servo pulse width in resolution provided by ServoDriver.getServoPulseResolution(). Zero value may mean that this driver is currently not producing pulse. Negative values may, generally, be invalid.

Specified by:

setServoPulseWidth in interface ServoDriver

Parameters:

width - pulse width in resolution read from ServoDriver.getServoPulseResolution()

getServoPulseResolution

public int getServoPulseResolution()

Description copied from interface: ServoDriver

This is read only value driver is to provide to users of this class. It defines resolution ServoDriver.getServoPulseWidth() and ServoDriver.setServoPulseWidth(int) methods are operating in. Resolution is provided in 1/n (ms) where value returned from this method is n.

Specified by:

getServoPulseResolution in interface ServoDriver

Returns:

resolution of servo pulse widths used in this interface

getPin

public Pin getPin()

Specified by:

getPin in interface ServoDriver
