Members

public Arduino_GigaDisplayTouch(TwoWire& wire, uint8_t intPin, uint8_t rstPin, uint8_t addr)

Construct a new touch controller for Giga Display Shield.

Parameters

  • wire A reference to the Wire interface to be used for communication with the touch controller.

  • intPin The interrupt pin number for the touch controller.

  • rstPin The reset pin number for the touch controller.

  • addr The device address for the touch controller.

public bool begin()

Initialize the touch controller.

Returns

true If the touch controller is successfully initialized, false otherwise

public void end()

De-initialize the touch controller.

public uint8_t getTouchPoints(GDTpoint_t* points)

Check if a touch event is detected and get the touch points.

Parameters

  • points The array containing the coordinates of the touch points.

Returns

uint8_t The number of detected touch points.

public void onDetect(void (*handler)(uint8_t, GDTpoint_t*))

Attach an interrupt handler function for touch detection callbacks.

Parameters

  • handler The pointer to the user-defined handler function.
