Provides interface to implement focuser functionality.
A focuser can be an independent device, or an embedded focuser within another device (e.g. Camera or mount).
When developing a driver for a fully indepdent focuser device, use INDI::Focuser directly. To add focus functionality to an existing mount or camera driver, subclass INDI::FocuserInterface. In your driver, then call the necessary focuser interface functions.
The interface supports three types of focusers:
- Absolute Position: Focusers that know their absolute position in steps on power up. You can issue GOTO to an absolute position. By definition, position 0 (zero) is where the focuser is completely retracted (i.e. closest to the OTA) and it increases positively as it move outwards. When moving inward, the position value decreases.
- Warning
- Negative values are not accepted for absolute focusers.
- Relateive Position: Focusers that can move in specific steps inwward or outward, but have no information on absolute position on power up.
- DC Motor: Focusers without any position feedback. The only way to reliably control them is by using timers and moving them for specific pulses in or out.
Implement and overwrite the rest of the virtual functions as needed. INDI GPhoto driver is a good example to check for an actual implementation of a focuser interface within a CCD driver.

MoveFocuser the focuser to an absolute position.
- Parameters
-
| ticks | The new position of the focuser. |
- Returns
- Return IPS_OK if motion is completed and focuser reached requested position. Return IPS_BUSY if focuser started motion to requested position and is in progress. Return IPS_ALERT if there is an error.

MoveFocuser the focuser in a particular direction with a specific speed for a finite duration.
- Parameters
-
| dir | Direction of focuser, either FOCUS_INWARD or FOCUS_OUTWARD. |
| speed | Speed of focuser if supported by the focuser. |
| duration | The timeout in milliseconds before the focus motion halts. Pass 0 to move indefinitely. |
- Returns
- Return IPS_OK if motion is completed and focuser reached requested position. Return IPS_BUSY if focuser started motion to requested position and is in progress. Return IPS_ALERT if there is an error.
