Member Function Documentation
| virtual bool calibrateStart | ( | ) | [pure virtual] |
| virtual bool getNextCalibratePoint | ( | uint16_t * | x, |
| uint16_t * | y | ||
| ) | [pure 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
- Returns:
- true if the request was successful; otherwise false
| virtual bool init | ( | uint16_t | width, |
| uint16_t | height | ||
| ) | [pure virtual] |
Initialize the touch controller.
This method must be called before calibrating or reading data from the controller
- Parameters:
-
width the width of the touch panel. This is usually the same as the width of the display height the height of the touch panel. This is usually the same as the height of the display.
- Returns:
- true if the request was successful; otherwise false
| virtual bool read | ( | touchCoordinate_t & | coord ) | [pure virtual] |
| virtual bool waitForCalibratePoint | ( | bool * | morePoints, |
| uint32_t | timeout | ||
| ) | [pure 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:
- true if the request was successful; otherwise false
