Member Function Documentation
| BiosTouch::TouchError calibrateStart | ( | ) | [virtual] |
Start to calibrate the display.
- Returns:
- Ok on success An error code on failure
Implements TouchPanel.
Definition at line 346 of file BiosTouch.cpp.
| BiosTouch::TouchError getNextCalibratePoint | ( | uint16_t * | x, |
| uint16_t * | y, | ||
| bool * | last = NULL |
||
| ) | [virtual] |
Get the next calibration point.
Draw an indicator on the screen at the coordinates and ask the user to press/click on the indicator. Please note that waitForCalibratePoint() must be called after this method.
- Parameters:
-
x the x coordinate is written to this argument y the y coordinate is written to this argument last true if this is the last coordinate in the series
- Returns:
- Ok on success An error code on failure
Implements TouchPanel.
Definition at line 357 of file BiosTouch.cpp.
| BiosTouch::TouchError info | ( | bool * | resistive, |
| int * | maxPoints, | ||
| bool * | calibrated | ||
| ) | [virtual] |
Returns information about the touch panel.
- Parameters:
-
resistive true for Resistive, false for Capacitive maxPoints the maximum number of simultaneous touches calibration true if the controller can be calibrated
- Returns:
- Ok on success An error code on failure
Implements TouchPanel.
Definition at line 324 of file BiosTouch.cpp.
| BiosTouch::TouchError init | ( | ) |
Initialize the touch controller.
This method must be called before calibrating or reading data from the controller
- Returns:
- Ok on success An error code on failure
Definition at line 252 of file BiosTouch.cpp.
| static BiosTouch& instance | ( | ) | [static] |
Get the only instance of the BiosTouch.
- Returns:
- The display
Definition at line 38 of file BiosTouch.h.
| bool isTouchSupported | ( | ) |
Tests if a touch controller is available or not.
Note that this function only returns a valid value after the display has been intitialized.
- Returns:
- true if there is a touch controller
Definition at line 336 of file BiosTouch.cpp.
| BiosTouch::TouchError read | ( | touch_coordinate_t * | coord, |
| int | num | ||
| ) | [virtual] |
Read up to num coordinates from the touch panel.
- Parameters:
-
coords a list of at least num coordinates num the number of coordinates to read
- Returns:
- Ok on success An error code on failure
Implements TouchPanel.
Definition at line 313 of file BiosTouch.cpp.
| BiosTouch::TouchError read | ( | touch_coordinate_t & | coord ) | [virtual] |
Read coordinates from the touch panel.
In case of multitouch (capacitive touch screen) only the first touch will be returned.
- Parameters:
-
coord pointer to coordinate object. The read coordinates will be written to this object.
- Returns:
- Ok on success An error code on failure
Implements TouchPanel.
Definition at line 302 of file BiosTouch.cpp.
| BiosTouch::TouchError waitForCalibratePoint | ( | bool * | morePoints, |
| uint32_t | timeout | ||
| ) | [virtual] |
Wait for a calibration point to have been pressed and recored.
This method must be called just after getNextCalibratePoint().
- Parameters:
-
morePoints true is written to this argument if there are more calibrations points available; otherwise it will be false timeout maximum number of milliseconds to wait for a calibration point. Set this argument to 0 to wait indefinite.
- Returns:
- Ok on success An error code on failure
Implements TouchPanel.
